“A davit arm is only as dependable as its base, its connections and the rescue plan behind it.”

A davit arm can provide an overhead attachment point for confined-space entry and retrieval. But setting one up involves more than placing an arm above an opening. The base must suit the structure, every component must be compatible, and the complete arrangement must work for the person entering the space and the team responsible for getting them out.

This guide explains the practical stages of setting up a davit arm for a workplace confined-space operation. It distinguishes the installation of a base or socket from the assembly and checks carried out before each use.

Jump to:

What Makes Up a Confined-Space Davit System?

A davit is usually part of a modular system. Depending on the manufacturer and application, that system may include:

• A fixed socket, wall-mounted base or approved portable base
• A mast or mast extension
• A davit arm with a specified reach
• Approved mounting brackets
• A personnel winch or suitable retrieval device
• A fall-arrest device where the risk assessment requires one
• Compatible connectors and a suitable harness

These components are not interchangeable simply because they appear to fit together. The permitted combination, working capacity and intended use must be confirmed from the manufacturer’s instructions and equipment markings.

If you need a broader explanation of what a davit does and where it is used, see our guide to davit arms.

1. Plan the Entry and Rescue Before Setting Up Equipment

Under UK confined-space guidance, the first question is whether entry can be avoided. If entry is necessary, the employer must assess the hazards, establish a safe system of work and put suitable emergency arrangements in place before anyone enters.

For a davit-assisted operation, the plan should establish:

• What the entrant is doing and what hazards exist inside the space
• The dimensions and position of the opening
• Where the base can be safely positioned
• Whether the arm has the reach needed to place the line appropriately over the entry point
• How the entrant will be connected to the retrieval system
• Whether the person can be brought through the opening without snagging
• Who will operate the equipment and who will coordinate the rescue
• What happens if non-entry retrieval is not possible

A davit does not, by itself, make a confined space safe to enter. Atmospheric testing, ventilation, isolation, communication, supervision and any permit arrangements must also be addressed where the risk assessment requires them.

Emergency services should not be the sole rescue arrangement. The site needs people, equipment and procedures capable of starting an appropriate response without waiting for an external team to arrive.

2. Choose and Verify the Davit Base or Socket

What is a davit arm base? It is the part of the system that supports the mast and transfers forces into a suitable structure or approved portable arrangement. The base may be permanently fixed or brought to the location for a particular job.

Common configurations include:

• Fixed floor or core-mounted sockets: installed at a designated entry point.
• Wall-mounted bases: fixed to a structure where the design permits.
• Portable or counterweighted bases: used only in the configurations and conditions approved by the manufacturer.

The choice depends on the entry location, supporting structure, available space, system loads and the intended rescue method. A socket that accepts a mast is not automatically suitable for that mast or safe for the planned operation.

Before using an existing base, confirm its identity, compatibility, condition and inspection status. Look for damage, corrosion, movement, missing fixings or changes to the structure around it. If its installation history or capacity cannot be established, have it assessed before relying on it.

For a new fixed base, the structure, fixings and installation method need to be assessed by a competent person. Any commissioning or pull testing should follow the applicable design and manufacturer requirements. An improvised pull test is not a substitute for verifying that the complete installation is suitable.

3. Assemble the Mast, Arm and Retrieval Equipment

Once the approved base is ready, trained users can assemble the system for the task. The exact sequence, locking arrangements and adjustments come from the instructions for that particular model.

The setup should confirm that:

• The mast and arm are approved for the base being used
• All sections are seated and secured as specified
• Locking pins or other retaining devices are present and correctly engaged
• The arm is positioned within its permitted reach and orientation
• The winch or retrieval device is attached using its approved bracket
• The line follows the manufacturer’s specified route and does not rub against an edge
• The harness connection and any separate fall-arrest arrangement suit the planned operation
• The configured system remains within its marked capacity

A system’s capacity can change with its configuration. Do not assume that a rating shown for one arm length, mounting position or application applies to another. Check the instructions for the assembled combination.

4. Carry Out Pre-Use Checks Before Entry

Pre-use checks help identify faults that may have developed since the last formal examination or the previous job. They should follow the instructions for the davit, base, winch, fall-protection equipment and harness.

Checks commonly address:

• Equipment identity and evidence that required formal examinations are current
• Visible damage, corrosion, distortion or missing parts
• The condition of the base, fixings and supporting structure
• Correct engagement of pins and locking mechanisms
• The condition of cable or rope, connectors, hooks and brackets
• Correct routing of the line and clearance from sharp edges
• Operation of the winch and other devices using the manufacturer’s prescribed checks
• A clear route for raising or lowering a person through the opening

Any defect, unexpected movement, failed check or uncertainty about compatibility should stop the setup being used until a competent person has assessed it. A successful inspection on a previous date does not excuse using visibly damaged equipment today.

The team should also confirm that everyone knows their role, communication arrangements work, and the rescue method remains practical under the actual site conditions.

What Is the Difference Between Installation and Daily Setup?

Keep the installation information, equipment instructions, examination reports and any test records available to the people planning and carrying out the work. If the base, surrounding structure or system configuration changes, review whether the previous assessment and records still apply.

If a system has failed an inspection or its technical information is incomplete, our guide to davit arm inspection failures explains some common next steps.

Davit Arm Setup FAQs

Can the same davit arm be used with several bases?

It may be possible if the manufacturer approves that mast and arm for each base. Every base must be suitable for its location and intended configuration. Check the identification and records for each installation.

Can I use a portable davit base instead of installing a socket?

Possibly. Some systems offer approved portable, counterweighted or vehicle-supported bases. They have specific setup conditions and limitations. Select one through the site risk assessment and follow its manufacturer’s instructions.

Does a davit arm need pull testing after installation?

Any commissioning test should be determined by the system design, manufacturer’s instructions and competent installer or engineer. Pull testing may be specified for a particular installation, but it is not a universal substitute for checking the base, fixings and supporting structure.

Can a davit arm be used to lift materials?

Only if the complete configuration is approved and marked for that use. A personnel retrieval system must not be assumed suitable for materials lifting, and equipment used to lift materials must not be assumed suitable for lifting people.

How many people can use one davit system?

That depends on the exact base, mast, arm, devices and configuration. Check the manufacturer’s stated limits and the rescue plan. Never infer a two-person capacity from the appearance of the equipment or from another model in the same range.

Do you need to inspect a davit before every use?

Yes. Users should carry out the pre-use checks required by the manufacturer and their safe system of work. Formal examination at the relevant interval is a separate requirement and does not replace those checks.

Can anyone assemble a davit arm?

Assembly should be carried out by people trained and competent to use that system and its retrieval equipment. A fixed base should be designed and installed by people competent for the structure, fixings and loads involved.

Is a davit arm enough for a confined-space rescue plan?

No. The plan must address the hazards, people, communication, equipment and actions needed for a foreseeable emergency. It should also account for situations where a person cannot be retrieved using the davit alone.

“An LEV test should tell you whether extraction still controls the dust or fume your workers are exposed to – not simply whether the fan turns on.”

If your workplace uses local exhaust ventilation (LEV) to control dust, fumes or vapours, you may have been told to book a Thorough Examination and Test, often shortened to TExT. What actually happens when the examiner visits?

A proper LEV examination checks the condition of the system, measures how it performs and assesses whether it is still capturing or containing the contaminant generated by the work. The examiner then provides a report explaining the findings and any action required.

Jump to:

What Is an LEV Thorough Examination and Test?

Local exhaust ventilation captures airborne contaminants close to where they are generated. Depending on your workplace, that could mean a welding extraction arm, woodworking dust system, spray booth, fume cupboard or on-tool extractor.

Under COSHH, LEV used to control exposure to hazardous substances needs to remain effective and undergo a competent Thorough Examination and Test at the required interval. For most systems, the maximum interval is 14 months; certain processes have shorter intervals. Our separate guide explains how often LEV should be tested.

This article focuses on what the examiner does during the visit and what the employer should expect afterwards.

1. What Happens Before the LEV Test Starts?

The examiner first needs to establish what the system is meant to control and how it is normally used. A system extracting wood dust should not be judged solely on whether its motor runs; the assessment needs to consider the machines, extraction points and working practices it serves.

Where available, the examiner reviews:

• The original commissioning report and intended performance figures
• The LEV user manual, system drawing and logbook
• Previous Thorough Examination and Test reports
• Records of maintenance, repairs or modifications
• The substances and work processes being controlled
• Any changes to machinery, layout or working methods since the last test

The visit also needs to be planned safely. Some systems require access to high-level ducts, moving machinery or equipment containing hazardous residues. Site staff may need to arrange safe access, isolation or a permit to work.

What if there is no commissioning report?

The examination can still proceed, but the examiner has less information against which to compare current readings. They may use suitable manufacturer information, recognised guidance or other evidence to assess performance, and should explain the limitation in the report.

For an undocumented system, establishing a fuller performance baseline or producing commissioning information may require additional work. The absence of old paperwork should not be hidden behind a simple “passed” label.

2. What Does the Physical Examination Cover?

HSE describes the first stage as a thorough visual and structural examination. The examiner checks whether the LEV is in good repair, clean enough to operate properly and free from defects that could undermine extraction.

Depending on the system, this may include:

• Hoods and extraction points: position, condition, damage and obstructions
• Ducting and flexible hoses: leaks, splits, blockages, loose connections and build-up
• Fans and drives: damage, wear and signs of poor operation
• Filters and collectors: condition, fitting and filter-cleaning mechanisms
• Gauges, airflow indicators and alarms: whether they operate and give useful warnings
• Discharge and make-up air arrangements: issues that may affect the system’s performance

The exact checks depend on the equipment. A portable on-tool extractor, a multi-branch woodworking system and an enclosed spray booth will not have identical examination procedures.

3. What Airflow and Pressure Measurements Are Taken?

The examiner uses suitable instruments to assess the LEV’s technical performance. Measurements may include air velocity, volume flow rate and static pressure at relevant points in the system. The readings can help reveal a restricted duct, blocked filter, unbalanced branch, failing fan or hood that is not receiving enough airflow.

Where commissioning figures exist, current results should be compared with those original benchmarks. This shows whether performance has changed. The examiner also considers whether the original figures and system design are appropriate for the process now being carried out.

Not every test involves every possible instrument. The method should suit the hood, process, contaminant and system design. If a workplace has several extraction points, the examination needs to address their performance rather than relying on one reading taken beside the fan.

4. How Does the Examiner Check Whether the LEV Actually Works?

The third stage is to assess control effectiveness: is the dust, fume or vapour being captured, contained or intercepted before people breathe it in?

The examiner may observe the process in normal operation and use appropriate methods such as smoke, a dust lamp or other visual techniques to understand where the airborne contaminant goes. They may check whether a movable extraction arm is close enough to the work, whether an enclosure contains the contaminant and whether surrounding draughts affect capture.

Worker behaviour matters too. An extraction arm may perform well when positioned correctly but provide little protection if it is routinely pushed out of the way. The examination should reflect how the equipment is actually used, and the report should explain any operating changes needed.

Personal exposure monitoring or air sampling is a separate assessment that may be appropriate in some higher-risk circumstances. It is not automatically included in every LEV TExT.

5. What Should the LEV Test Report Tell You?

After the visit, you should receive a written report that lets you identify the system examined, understand its measured performance and act on any problems found.

A useful report should include, as applicable:

• The identity and location of the LEV system and the process it serves
• The date of examination and the conditions under which it was tested
• The parts and extraction points examined
• The tests and measurements taken, with relevant comparison figures
• An assessment of whether the system is controlling exposure effectively
• Defects, failed hoods or limitations in the examination
• Prioritised actions needed to restore or improve control
• The examiner’s details and the next examination requirement

HSE advises examiners to label tested hoods and use a clear fail label, or equivalent, for hoods that do not provide adequate control. A failed point should not be left looking available for normal use with the problem buried in a report.

Employers should keep LEV examination and test reports for at least five years and make them available where the system is used. The person responsible for health and safety and the person responsible for maintenance should both see the findings.

What Happens If the LEV Fails?

A failed or significantly defective extraction system needs action. The report should explain which part failed, why that matters and what needs to happen next. Depending on the fault, work could involve repositioning a hood, repairing ducting, replacing a filter, adjusting a damper, restoring fan performance or changing the working method.

The employer must decide how to prevent harmful exposure while the problem is being resolved. That may mean stopping the affected task, changing the process or using other suitable controls identified through the COSHH assessment. Once repairs or changes are complete, further testing may be needed to confirm that effective control has been restored.

A TExT identifies and documents the issue. It does not automatically include all the maintenance and remedial work required to put the system right. For that distinction, see our guide to LEV inspection versus maintenance.

How Can You Prepare for an LEV Examination?

Having the system and its records ready helps the examiner assess its real operating performance. Before the visit:

• Locate the commissioning report, previous test reports and logbook if available
• Identify every hood, branch or extraction unit that needs examining
• Explain any changes to machinery, substances or processes
• Arrange access to the equipment and suitable site supervision
• Plan for the relevant process to be demonstrated safely, where needed
• Explain known faults rather than waiting for the examiner to discover them

If records are missing, tell the provider when booking. They can then explain what can be established during the examination and whether additional baseline work may be necessary.

LEV Thorough Examination and Test FAQs

Is an LEV test just an airflow reading?

No. Airflow and pressure readings help assess technical performance, but an LEV TExT also examines the physical condition of the system and whether it effectively controls the contaminant during the work.

Does the machinery need to be running during the test?

The examiner may need to observe the normal process to judge capture or containment effectiveness. The precise arrangements depend on the equipment, hazard and safe system of work. Agree access and operating requirements before the visit.

Can LEV be tested without an original commissioning report?

Yes, but the missing baseline limits direct comparison with the system’s intended performance. The examiner should explain what information was used to reach a judgement and identify any further work needed to establish suitable benchmarks.

Does a passed LEV test mean no maintenance is needed?

No. Routine checking, cleaning and maintenance continue between statutory examinations. The report may also identify developing wear or actions needed before the next test.

Does a TExT include personal air monitoring?

Not automatically. The examiner may use visual methods and system measurements to assess control effectiveness. Personal exposure monitoring is a distinct assessment that may be needed where the risk and circumstances justify it.

What should I do if an extraction hood fails?

Review the examiner’s findings, prevent workers relying on ineffective extraction and arrange the required corrective work. The COSHH assessment should guide how the affected task is controlled until effective LEV performance is restored.

“An anchor point is only suitable if the whole system – including its fixings, supporting structure and intended use – has been considered.”

A worker may see a metal eye on a roof or wall and assume it is a safe place to clip on. Its appearance cannot tell them whether it was designed for fall arrest, how many people may use it, or whether the structure behind it can withstand the forces involved.

So what are the requirements for a fall arrest anchor point in the UK? There is no single answer based on the appearance of the fitting or a universal “weight rating”. The anchor must be suitable for the specific personal fall protection system, number of users, location and supporting structure. Its design, installation, permitted use and inspection arrangements should be identifiable.

Jump to:

What Is a Fall Arrest Anchor Point?

A fall arrest anchor point is a place where a worker connects a personal fall protection system. Depending on the installation, that connection could be provided by an anchor device, an eyebolt, a roof anchor or another designed arrangement.

Its role is to support the connected system if a fall occurs. But the visible point is only part of the picture. The device, fixings, base material, wider structure, harness, connecting equipment and rescue arrangements must work together.

An ordinary lifting eye, handrail or convenient piece of steelwork should not be treated as a fall arrest anchor merely because a connector fits around it. Its suitability must be established for the intended task and loads.

What Are the Main Requirements for a Suitable Anchor?

1. The method of work must justify personal fall protection

HSE’s work-at-height hierarchy starts with avoiding work at height where reasonably practicable. Where that is not possible, measures that prevent a fall, particularly those protecting everyone at risk, should be considered before relying on personal fall arrest.

An anchor point is therefore part of a planned system of work. Installing one does not, by itself, make a roof edge or other work-at-height task safe.

2. The intended use must be clear

An anchor may be intended for work restraint, where the system prevents a worker reaching a fall position, or for fall arrest, where the system must stop a fall after it begins. Other applications include rope access, work positioning and rescue.

These uses can place different demands on the anchor system. The system documentation and markings should make its permitted applications and limitations clear. Do not assume an anchor approved for one task is suitable for every other task.

3. The device and supporting structure must be suitable

The strength of a manufactured anchor device is only one consideration. The fixings and material it is attached to must also be suitable. A competent design and installation process should consider the structure, substrate, edge distances, fixing arrangement, condition and forces that the intended system could impose.

For example, a correctly manufactured roof anchor cannot be relied upon if its fixings have been installed into a structure that has not been verified for the intended use.

4. Position and fall clearance must be considered

Where an anchor is placed affects how a connected system performs. The design needs to consider the worker’s route, potential swing or pendulum movement, sharp edges and the distance available below the worker if a fall occurs.

A strong anchor in the wrong position can still leave a worker at risk of striking the ground, the building or an obstruction. The compatible harness and connecting equipment must be considered as part of that assessment.

5. The number of users must be specified

Do not assume that two workers may connect to an anchor because there is room for two connectors. The permitted number of simultaneous users should be supported by the design and manufacturer information for that particular device and system.

6. There must be a rescue plan

Fall arrest stops a person falling further; it does not automatically get them to safety. Work-at-height planning must consider how a suspended worker would be rescued promptly, using arrangements suited to the site and task.

What Is the Minimum Anchor Rating for Fall Arrest in the UK?

There is no single “how much weight must it hold?” figure that answers this for every UK fall arrest anchor. A person’s body weight is not the same as the forces that may be generated during a fall. The required performance depends on factors including the type of anchor, number of users, system configuration and intended use.

Online answers sometimes quote a particular figure in kilonewtons or pounds-force without explaining whether it is a product test requirement, a design load, a proof-test load or a requirement from another country’s rules. Those figures cannot safely be substituted for one another.

For a real installation, establish:

• The anchor device and standard or specification applicable to it
• The permitted use and number of users
• The loads imposed by the complete fall protection system
• The capacity and condition of the supporting structure
• The manufacturer’s installation and use instructions
• The design and installation documentation for the site

If those details are missing, a number stamped on the visible fitting is not enough to confirm that the entire installed system is suitable. A competent person may need to review the original records, inspect the installation or investigate the structure.

Which UK Standards Apply to Fall Protection Anchors?

Several standards are relevant, but they have different scopes. Selecting the right one starts with understanding whether you are assessing a manufactured device, an installed system, a single-user arrangement or one intended for multiple users.

These standards provide technical requirements and guidance. The legal duties to plan work at height, select suitable equipment and manage the risks arise from the Work at Height Regulations 2005. A competent designer or examiner should identify which standards and system requirements apply to the actual installation.

What Documentation Should Be Available for an Installed Anchor System?

A site should be able to establish what each anchor is for and the conditions under which workers may use it. Depending on the system, useful information can include:

• The anchor’s identification and location
• Its intended use and permitted number of users
• Manufacturer and device information
• The system design and installation specification
• Details of fixings and the supporting structure
• Installation and commissioning records
• Operating limitations and compatible equipment
• An examination scheme and inspection history
• Instructions for access and rescue arrangements

BS 7883:2019 places particular emphasis on system design information, a technical file, operating information and an examination scheme. These records help future users and inspectors understand what was installed, rather than trying to infer its suitability from a label alone.

Can You Use an Existing Eyebolt or Roof Anchor?

Potentially, but first establish what it was installed for. An existing anchor may have missing records, an unknown fixing arrangement, changes to the surrounding structure or an intended use that differs from the work now planned.

Before relying on it, check whether its identification, permitted use and current inspection status can be established. Where the installation cannot be verified, the appropriate next step is a competent assessment. A routine visual check or an arbitrary pull test cannot automatically resolve missing design or structural information.

For the examination regime once an anchor is in service, see our separate guide: How Often Should Fall Arrest Anchor Points and Eyebolts Be Tested?

What If an Anchor Is Found to Be Unsuitable?

Do not leave an uncertain or failed anchor available for workers to clip onto. Identify it clearly, prevent its use and arrange a suitable alternative means of carrying out the work.

Depending on the issue, the solution may be further investigation, structural verification, remedial work, replacement or a redesigned fall protection system. The outcome should be documented so that workers and contractors know which points they can use.

Fall Arrest Anchor Point FAQs

What are acceptable anchor points for fall arrest?

Acceptable points are those established as suitable for the intended personal fall protection system, number of users and supporting structure. Do not assume that a handrail, lifting eye or unmarked fitting is an acceptable fall arrest anchor.

How much weight should a fall arrest anchor hold?

There is no universal answer expressed as a person’s weight. The system must be designed for the forces and use conditions that apply to it. The anchor device, fixings and structure all need to be considered.

Can two people use the same anchor point?

Only where the anchor system has been designed, assessed and identified for simultaneous use by two people. A single-user device should not be treated as a two-user anchor simply because both connectors physically fit.

Is an anchor point the same as an eyebolt?

No. An eyebolt is one possible form of anchor device. Fall protection systems can also incorporate roof anchors, rails, lines, overhead anchors and other arrangements.

Does every anchor point need a pull test?

No single pull-test procedure applies to every system. Whether testing is needed, and how it should be carried out, depends on the device, installation, manufacturer instructions and examination scheme. Inspection also considers matters that a pull test alone cannot establish.

Can an old anchor without paperwork still be used?

Its suitability needs to be established before use. A competent person may be able to investigate the anchor, installation and supporting structure, but an unidentified point should not be assumed safe because it looks sound.

“For a fire involving electrical equipment, the right extinguisher matters. So does knowing when to leave it alone.”

A CO₂ fire extinguisher is commonly used for fires involving electrical equipment. It contains an electrically non-conductive gas and leaves no powder or liquid residue. You will often find one near office electrical equipment, plant rooms or other identified electrical risks.

But “electrical fire” does not tell you everything you need to know. The equipment may still be live, and the material burning could be plastic, paper, insulation or something else nearby. The first priority is to raise the alarm and get people to safety. Electrical power should only be isolated if it is safe to do so.

Jump to:

What Is the Best Fire Extinguisher for an Electrical Fire?

For many ordinary workplace risks involving electrical equipment, the answer is a carbon dioxide (CO₂) extinguisher. Its extinguishing medium does not conduct electricity, and it does not leave a powder or liquid deposit across the equipment.

That makes CO₂ a common choice near electrical cabinets, machinery controls and office equipment. A premises may also need other extinguishers to cover the surrounding materials. A CO₂ extinguisher provided for an electrical risk does not replace the need to assess fires involving paper, packaging, furnishings or other combustible materials.

CO₂ has limits. It provides little cooling, so a fire involving hot material may reignite. Discharging CO₂ in a small, poorly ventilated space can also create a risk to people, and the discharge horn can become extremely cold. Staff should be trained on the equipment provided and should never put themselves at risk to save property.

Which Types of Extinguisher Can Be Used Around Electrical Equipment?

Some water-based extinguishers carry a label showing that their discharge passed an electrical conductivity test. That marking has a specific meaning; it does not make every water-based extinguisher an appropriate choice for a live electrical hazard. Current BS 5306-8 guidance calls for non-conductive extinguishing media to be specified for live electrical equipment. If your site has water mist or another specialist unit, have a competent person check its exact approval and intended use.

Is an Electrical Fire a Class E Fire in the UK?

No. “Class E” is sometimes used informally, but it is not one of the standard UK fire classes used to identify what is burning. Electricity is an additional hazard because the equipment may be energised. The burning material still determines the fire class.

For example, an overheated appliance could ignite plastic casing or nearby paper. Cutting the electrical supply, where safe, removes the electrical hazard, but it does not necessarily put out the burning material. That is why the fire risk assessment must consider both the equipment and the surrounding fuel when choosing extinguishers.

What Should You Do If Electrical Equipment Catches Fire?

1. Raise the alarm and start the evacuation procedure. Warn others and make sure the fire and rescue service is called.
2. Keep clear of the equipment. Do not touch burning equipment, damaged cables or a switch that cannot be reached safely.
3. Isolate the electrical supply only if safe. Equipment can remain energised even when it appears to have been switched off. Do not delay your escape to find an isolator.
4. Only consider an extinguisher if workplace procedures allow it. The fire must be small, the extinguisher suitable, the person trained and the exit route clear.
5. Leave immediately if there is any doubt. Smoke, a spreading fire or an uncertain power supply are reasons to evacuate, close doors where safe and wait for the fire and rescue service.

An extinguisher is provided for an early-stage incident. It is not a reason to remain in a dangerous area or try to protect equipment at the expense of personal safety.

How Should a Business Choose and Position Extinguishers for Electrical Risks?

The starting point is the premises’ fire risk assessment. It should identify the electrical equipment and other fire hazards, who may be affected, how people will escape and whether suitable first-aid firefighting equipment is needed.

When reviewing extinguisher provision, consider:

• The actual hazard: small office appliances are different from switchgear, production machinery or a specialist plant room.
• What else could burn: packaging, furnishings, flammable liquids or other nearby materials may require additional extinguisher types.
• Accessibility: a suitable extinguisher should be visible and reachable without moving towards the hazard or blocking an escape route.
• The room: an enclosed or occupied space may affect whether CO₂ or powder is appropriate.
• Training: nominated staff need to know which extinguisher is provided, what it can be used on and when to evacuate.
• Maintenance: extinguishers need to remain in their intended position and be kept in working order.

The Regulatory Reform (Fire Safety) Order 2005 requires appropriate firefighting equipment where necessary for the safety of people, and a suitable system of maintenance for equipment provided. BS 5306-8:2023 gives detailed guidance on selecting and positioning portable extinguishers; BS 5306-3 addresses commissioning and maintenance.

If you are fitting out a new workplace or are unsure whether existing units match the risks, a fire extinguisher survey can identify gaps before new equipment is selected.

Does a CO₂ Extinguisher Cover Every Electrical Fire?

No. A CO₂ extinguisher is a common provision for ordinary electrical equipment risks, but its suitability depends on the whole incident. It may suppress flames without adequately cooling burning materials, which can lead to reignition.

Lithium-ion battery incidents need separate consideration. A battery entering thermal runaway can produce intense heat, hazardous gases and repeated ignition. A CO₂ extinguisher provided for a standard electrical cabinet should not be assumed capable of controlling a burning e-bike battery, battery storage system or electric vehicle. Such risks need a specific assessment and emergency plan.

Choosing the Right Equipment for Your Site

The practical question for an employer is not simply “Do we own a CO₂ extinguisher?” It is whether the right equipment is available in the right place for the risks identified, and whether staff understand when to use it.

Velocity Safety supplies, positions and commissions fire extinguishers for workplaces across the UK. We can review your electrical and general fire risks, recommend suitable extinguisher types and provide installation records for your fire safety documentation.

Electrical Fire Extinguisher FAQs

What colour is the extinguisher used for electrical fires?

A CO₂ extinguisher has a black identification panel on its red body. Check the label rather than relying on colour alone: it identifies the extinguishing medium, instructions and relevant fire ratings.

Can you use a water extinguisher on an electrical fire?

Do not assume a standard water extinguisher is safe for live electrical equipment. Some specialist water-based extinguishers carry electrical test markings, but their permitted use is specific. The employer should specify suitable equipment based on the fire risk assessment and current guidance.

Can you use a powder extinguisher on electrical equipment?

Suitable non-conductive powder can be used for electrical risks. However, its discharge can reduce visibility, affect breathing and contaminate equipment. This makes powder a poor default choice for many occupied indoor spaces.

Should you switch off the power before using an extinguisher?

Electrical equipment should be disconnected or isolated before an extinguisher is discharged onto it, if that can be done safely. Never touch damaged equipment or put yourself in danger to reach a switch. Some equipment may remain live even when it appears to be off.

Are CO₂ extinguishers suitable for lithium-ion battery fires?

Do not assume so. A lithium-ion battery in thermal runaway presents a different risk from an ordinary electrical equipment fire. Battery charging and storage hazards should have their own fire risk assessment and emergency arrangements.

Is an electrical fire called a Class E fire?

“Class E” is an informal label sometimes seen online. In UK fire classification, electricity is treated as a hazard associated with the fire rather than a separate class of burning material.

“Service-free does not mean maintenance-free. P50 fire extinguishers still require a recorded annual inspection.”

A P50 fire extinguisher is a lightweight composite extinguisher designed to provide long-life fire protection with reduced external servicing requirements.

Unlike conventional steel extinguishers, Britannia P50 extinguishers do not require an external annual service during their first 10 years. However, the prescribed annual maintenance inspection must still be completed and recorded by a trained, competent person.

Different P50 models are designed for different fire risks, so the correct extinguisher must be selected according to your premises and fire risk assessment.

Instead of a conventional steel cylinder, the internal P50 bottle is manufactured from high-density polyethylene and wound with a strong aramid fibre. The extinguisher also has a UV-protected outer jacket and corrosion-resistant components.

This construction is intended to provide:

• A lighter extinguisher than many equivalent steel models
• Resistance to corrosion in damp or exposed environments
• A long operational lifecycle
• Reduced external servicing requirements
• Double pressure gauges for completing the prescribed annual inspection

P50 extinguishers are available in several sizes and extinguishing media. The term “P50” therefore describes the product range and construction rather than one universal extinguisher suitable for every fire.

A competent assessment is still required to decide which models your premises need.

What Can P50 Fire Extinguishers Be Used For?

What a P50 fire extinguisher can be used for depends on the model and extinguishing medium.

Velocity Safety currently supplies and installs 6-litre P50 water mist and 6kg P50 ABC powder extinguishers. These two models are designed for different workplace risks.

6-Litre P50 Water Mist Extinguishers

The 6-litre water mist model is primarily designed for Class A fires involving ordinary combustible materials such as:

• Paper
• Wood
• Cardboard
• Textiles
• Many furnishings and general workplace combustibles

This makes water mist P50 extinguishers suitable for many offices, schools, accommodation premises, healthcare settings, retail units and other commercial buildings.

The Britannia 6-litre P50 water mist extinguisher has also passed the applicable EN3 test for use near live electrical equipment up to 1000V.

This does not mean that every electrical risk should automatically be covered by water mist. The equipment, working environment and fire risk assessment should be considered when selecting extinguishers.

6kg P50 ABC Powder Extinguishers

ABC powder P50 extinguishers can cover:

• Class A fires – Solid combustible materials
• Class B fires – Flammable liquids
• Class C fires – Flammable gases

They may be suitable for industrial premises, workshops, construction sites, external fire points, vehicles, yards and other mixed-risk environments.

Powder can create a cloud that affects visibility and leaves significant residue. It can also damage sensitive equipment. This means powder extinguishers should be selected according to the specific environment rather than treated as the default option for every indoor workplace.

What Types of P50 Fire Extinguisher Are Available?

The wider Britannia P50 range includes water mist, powder, foam and specialist models. This is why search terms such as “P50 foam fire extinguisher” and “P50 Eco fire extinguisher” may return products with different capabilities.

Velocity Safety’s principal P50 installation options are the 6-litre water mist and 6kg ABC powder models.

Not every premises should use only one type. A site may require water mist extinguishers in occupied buildings and ABC powder models at suitable external or industrial fire points.

A fire extinguisher survey can establish the correct models, quantities and locations.

Are P50 Fire Extinguishers Really Service-Free?

P50 extinguishers are frequently described as “service-free” because an external annual servicing contract is not required during their first 10 years.

This does not remove the need for maintenance.

The prescribed annual inspection must be completed by a trained and competent person. The result should also be recorded so the business can demonstrate that the extinguisher has been checked.

The inspection should be completed in accordance with the manufacturer’s instructions and the organisation’s fire safety procedures. It includes checks covering matters such as:

• The condition of the extinguisher and its outer body
• The pressure shown by its gauges
• Whether the gauges respond correctly during the prescribed test
• The condition of the operating mechanism, pin and tamper seal
• Evidence of damage, interference, leakage or discharge
• Whether the instructions and identification remain legible
• Whether the extinguisher remains correctly located and accessible
• Whether the inspection has been recorded

Anyone responsible for these checks needs suitable training and must understand when an extinguisher should be removed from service or referred for further examination.

How Long Does a P50 Fire Extinguisher Last?

Britannia P50 extinguishers are designed with a 20-year lifecycle.

The first stage covers the initial 10-year period, during which the required annual maintenance inspections must be completed and recorded.

At 10 years, the extinguisher requires a manufacturer’s overhaul. Once the overhaul has been completed successfully, the extinguisher can enter a second 10-year period.

Its full lifecycle is therefore dependent on:

• Correct initial selection and installation
• Completion of the prescribed annual inspections
• Suitable storage and environmental conditions
• No damage, discharge or interference that makes the extinguisher unserviceable
• The required manufacturer’s overhaul after 10 years

A 20-year lifecycle should not be treated as an unconditional guarantee that every extinguisher will remain suitable regardless of its condition.

Are P50 Fire Extinguishers Legal in the UK?

Yes. P50 fire extinguishers can form part of a compliant fire protection system when the products are appropriate for the risks present and are correctly installed, commissioned and maintained.

Britannia states that the P50 range carries approvals and certification including the BSI Kitemark, UKCA, EN3 and PED.

However, UK fire safety law does not simply approve premises because they contain a particular brand or model of extinguisher.

The person responsible for a non-domestic premises must assess its fire risks and put appropriate fire safety measures in place. Government guidance also states that firefighting equipment must be properly installed, tested and maintained.

The responsible person may be an employer, owner, landlord, occupier, facilities manager, managing agent or another person with control of the premises. The precise legislation differs across England and Wales, Scotland and Northern Ireland.

The practical question is therefore not only whether P50 extinguishers are legal. It is whether:

• The selected models are suitable for the identified fire risks
• Enough extinguishers have been provided
• They have been positioned and identified correctly
• They have been commissioned and documented
• The prescribed maintenance process is being followed

Simply purchasing P50 extinguishers online does not answer these site-specific questions.

P50 Fire Extinguishers vs Traditional Steel Extinguishers

P50 and conventional steel extinguishers can both provide effective fire protection when they are correctly selected and maintained. The main differences concern their construction, servicing process and potential lifecycle.

The most appropriate option depends on the premises, fire risks, number of units, existing equipment and how the organisation manages ongoing maintenance.

Velocity Safety can assess an existing extinguisher estate and determine whether a complete or phased transition to P50 equipment is appropriate.

How Much Do P50 Fire Extinguishers Cost?

The cost of P50 fire extinguishers depends on:

• The extinguisher model and capacity
• The number of extinguishers required
• Whether a site assessment is needed
• Installation and commissioning requirements
• The brackets, stands or cabinets required
• Identification and fire point signage
• The number and location of premises
• Removal or disposal of existing equipment

Comparing the price of one P50 extinguisher with one conventional extinguisher does not necessarily provide a useful whole-life comparison.

The evaluation should also consider servicing costs, replacement intervals, the 10-year manufacturer’s overhaul, internal inspection responsibilities and the administrative requirements of managing the equipment.

Velocity Safety provides site-specific quotations covering the required P50 extinguishers, installation, commissioning and accessories.

Who Are P50 Fire Extinguishers Suitable For?

P50 extinguishers may be suitable for organisations looking to reduce external servicing requirements or standardise their fire protection across several premises.

Potential applications include:

• Offices and commercial buildings
• Schools, colleges and public-sector premises
• Healthcare and accommodation settings
• Warehouses and logistics facilities
• Manufacturing premises and workshops
• Construction sites and temporary compounds
• Facilities teams managing several buildings
• Outdoor or exposed fire points requiring corrosion-resistant equipment

The product’s maintenance model may be particularly attractive to multi-site organisations. However, the business must still have a reliable process for training competent personnel, completing annual inspections and retaining the necessary records.

Do P50 Fire Extinguishers Require Installation and Commissioning?

Yes. The reduced servicing requirements of P50 extinguishers do not remove the need for correct initial installation and commissioning.

Before installation, the provider should establish:

• The fire classes and specific risks present
• The correct extinguisher models and quantities
• Where each extinguisher should be positioned
• Whether wall brackets, stands or cabinets are required
• What identification signage is needed
• Whether any existing extinguishers should be retained, relocated or removed

The extinguishers should then be installed securely, commissioned and added to the site’s fire safety records.

A proper handover should also explain the annual inspection process and identify who will be responsible for completing and recording it.

Learn more about fire extinguisher commissioning and decommissioning.

Final Takeaway

A P50 fire extinguisher is a long-life composite extinguisher that can reduce the need for conventional external annual servicing.

Its main benefits include corrosion-resistant construction, a potential 20-year lifecycle and a maintenance system that can be managed in-house by an appropriately trained and competent person.

However, P50 extinguishers are not genuinely maintenance-free.

They must still be:

• Selected according to the fire risks present
• Installed and commissioned correctly
• Inspected annually using the prescribed procedure
• Recorded within the organisation’s fire safety documentation
• Overhauled by the manufacturer after 10 years if they are to enter their second 10-year period

The safest starting point is a site assessment that identifies the correct water mist, powder or combined provision for your premises.

Frequently Asked Questions

What does P50 mean on a fire extinguisher?

P50 is the name of Britannia Fire’s range of composite fire extinguishers. It describes the product family rather than one particular extinguishing medium or fire classification.

What can a P50 fire extinguisher be used for?

That depends on the model. A 6-litre P50 water mist extinguisher is principally suitable for Class A combustible-material fires and has been tested for use near live electrical equipment up to 1000V. A 6kg P50 ABC powder extinguisher can cover Class A, B and C risks.

Are all P50 fire extinguishers foam extinguishers?

No. The P50 range includes water mist, powder, foam and specialist models. The extinguisher label and fire rating must be checked to establish what a particular P50 can be used for.

Do P50 fire extinguishers need annual servicing?

They do not require a conventional external annual service during their first 10 years when the manufacturer’s prescribed annual inspection is completed correctly. That inspection must still be undertaken and recorded by a trained, competent person.

Are P50 fire extinguishers completely maintenance-free?

No. P50 extinguishers require annual maintenance checks and must be removed from use or investigated if they are damaged, discharged, tampered with or found to be outside the acceptable condition.

How long does a P50 extinguisher last?

P50 extinguishers have a potential 20-year lifecycle. A manufacturer’s overhaul is required after 10 years before an extinguisher can enter its second 10-year period.

Are P50 fire extinguishers legal in the UK?

Yes, provided they are suitable for the identified risks and are correctly installed, commissioned and maintained. Compliance depends on the overall fire risk assessment and fire protection arrangements, not simply the brand of extinguisher purchased.

Can P50 water mist extinguishers be used on electrical equipment?

Britannia’s P50 water mist extinguisher has passed the applicable EN3 test for use near live electrical equipment up to 1000V. The correct extinguisher provision should nevertheless be selected according to the equipment, environment and site fire risk assessment.

Are P50 extinguishers suitable for outdoor use?

Their corrosion-resistant composite construction can make P50 extinguishers suitable for demanding or exposed environments. Appropriate cabinets, stands and mounting arrangements may still be required to protect the equipment and maintain accessibility.

Can a business inspect its own P50 extinguishers?

The prescribed annual inspection can be managed in-house where the person completing it has received appropriate training and is competent to follow the manufacturer’s procedure, identify problems and maintain the required records.

Do P50 extinguishers need to be commissioned?

Yes. New P50 extinguishers should be correctly positioned, securely installed, commissioned and documented before being placed into service.

Where can I buy P50 fire extinguishers near me?

Velocity Safety is based in Blackburn, Lancashire, and supports businesses across the North West, including Lancashire, Greater Manchester, Merseyside, Cheshire and Cumbria. UK-wide P50 supply, installation and commissioning is also available for individual and multi-site organisations.

“A recent calibration does not prove that your portable gas detector will respond correctly today.”

A bump test and a calibration are not the same procedure.

Calibration checks the accuracy of a portable gas detector against a known concentration of test gas and allows the instrument to be adjusted where necessary.

A bump test is a quicker functional check used to confirm that gas can reach the sensors, the sensors respond and the detector’s alarms activate.

Portable gas detectors may therefore need both periodic calibration and bump testing before each day’s use.

Learn more about Velocity Safety’s gas detector calibration services.

Jump to:

Gas Detector Bump Test vs Calibration

Bump testing and calibration both involve exposing a gas detector to test gas, but they serve different purposes.

Sending a portable detector away for calibration every few months does not confirm that it remains functional on every day between calibrations.

Why Is Bump Testing Important?

Portable gas detectors are used to warn workers about potentially dangerous atmospheres, including toxic gases, flammable gases and oxygen deficiency or enrichment.

Their sensors can be affected by:

• Exposure to high gas concentrations
• Sprays, solvents, paints, vapours or greases
• Sensor poisons or inhibitors
• Dirt, dust or blocked sensor openings
• Impact or physical damage
• Incorrect storage or unsuitable environmental conditions

Some faults may not be identified by simply switching the detector on.

The display, lights and audible alarm might appear operational while a damaged, obstructed or inhibited sensor fails to respond correctly to the target gas.

A bump test challenges the detector using actual test gas. This provides a practical check that the gas reaches the sensor and the detector responds.

How Often Should a Portable Gas Detector Be Bump Tested?

HSE notes that the operating instructions for most gas detectors recommend a function check—commonly called a bump test—before each day’s use.

The correct procedure should be based on:

• The detector manufacturer’s instructions
• The gases and sensor types involved
• The employer’s risk assessment
• The safe system of work
• Site conditions and potential contaminants
• Any impact, unusual exposure or suspected equipment fault

Additional testing may be appropriate after the detector has been dropped, exposed to a high gas concentration or subjected to substances that could affect its sensors.

For guidance on periodic calibration intervals, see our article explaining how often gas detectors should be calibrated.

How Is a Gas Detector Bump Test Performed?

The exact method depends on the detector and its manufacturer’s instructions.

A typical manual bump test uses:

• A suitable cylinder containing the required test gas
• The correct fixed-flow regulator
• Compatible tubing and a detector adaptor
• A safe and suitably ventilated testing area

The detector is exposed to test gas so the operator can confirm that the relevant sensors respond and the audible, visual and vibration alarms operate correctly.

Automatic test stations can also apply gas, assess the detector’s response and create an electronic record of the outcome.

Only compatible gas, regulators, adaptors and test procedures should be used. The applicable manufacturer’s instructions must always be followed.

What Happens If a Gas Detector Fails a Bump Test?

A portable gas detector that fails its bump test should not be relied upon for confined-space entry or other hazardous-atmosphere work.

The instrument should be removed from use and investigated in accordance with the manufacturer’s instructions.

Depending on the result, this may involve:

• Checking that the correct test gas and equipment were used
• Checking the gas cylinder’s concentration and expiry date
• Inspecting tubing, adaptors and sensor openings
• Completing a full calibration
• Replacing a failed or contaminated sensor
• Sending the detector for servicing or repair

If the detector cannot successfully complete the required checks, it should remain out of service.

Final Takeaway

A calibration certificate does not replace a pre-use bump test.

Calibration checks whether a gas detector responds accurately against a known standard. Bump testing checks whether the detector can respond and alarm when it is needed.

Portable gas detectors can be affected at any point between scheduled calibrations, which is why bump testing forms an essential part of a properly managed gas-detection procedure.

Frequently Asked Questions

Is a gas detector bump test the same as calibration?

No. A bump test confirms that the detector responds to gas and activates its alarms. Calibration checks its response against a known gas concentration and allows adjustment where required.

Does a calibrated gas detector still need bump testing?

Yes, where required by the manufacturer’s instructions or the employer’s testing procedure. A detector can become damaged, obstructed or contaminated after calibration and before its next scheduled service.

Should portable gas detectors be bump tested every day?

HSE states that most gas-detector operating instructions recommend a function check before each day’s use. Employers should follow the applicable manufacturer’s instructions and establish an appropriate testing procedure for the equipment and risks involved.

What should happen after a failed bump test?

The detector should be removed from use and investigated. It may require another correctly performed test, full calibration, servicing, sensor replacement or repair before being returned to use.

Can a detector pass its self-test but fail a bump test?

Yes. A start-up self-test may check the detector’s electronics, display and alarms without proving that its sensors can respond correctly to the target gas. A bump test exposes the sensors to test gas.

“A great couple of days in Plymouth providing PortaCount 8040 and RPE competent person training.”

Velocity Safety recently travelled to Plymouth to provide two days of respiratory protective equipment training for ISAR3 – Industrial Safety Access & Rescue.

The visit combined training on the TSI PortaCount 8040 with additional instruction for the RPE competent person role, including training on performing monthly RPE examinations.

Two Days of RPE Training in Plymouth

The two-day visit provided the ISAR3 team with training on the TSI PortaCount 8040.

The PortaCount 8040 is used for quantitative face fit testing, providing a numerical fit factor for the respirator being tested.

Training was delivered directly to the team in Plymouth, allowing the equipment and testing process to be covered together during the visit.

TSI PortaCount 8040 Training

The first part of the visit focused on the TSI PortaCount 8040.

This equipment is used to perform quantitative face fit tests on applicable tight-fitting respiratory protective equipment.

ISAR3 received training on using the PortaCount 8040 as part of the two-day programme.

For organisations requiring face fit testing, Velocity Safety provides Fit2Fit-accredited qualitative and quantitative face fit testing for workers using tight-fitting RPE.

RPE Competent Person Training

Additional training was provided for the RPE competent person role.

This included training on performing the monthly examinations required for applicable reusable respiratory protective equipment.

The competent-person training was delivered alongside the PortaCount programme, allowing both face fit testing and the examination of RPE to be addressed during the visit.

Velocity Safety also provides documented RPE inspections and RPE examination and servicing support.

Completing the Training

After two days in Plymouth, the PortaCount 8040 and additional RPE competent person training were completed.

It was a pleasure working with the ISAR3 team and finally meeting Phil Turner in person.

Thank you to everyone at ISAR3 for having us.

Velocity Safety is now an authorised G-Force service agent and distributor for G-Force fall arrest blocks and products.

The new authorisation follows significant investment in training, specialist tooling, servicing jigs and spare parts.

Customers can now contact Velocity Safety about the supply, inspection and manufacturer-authorised servicing of applicable G-Force equipment.

Enquire about G-Force fall arrest block servicing.

New G-Force Fall Arrest Block Servicing Capability

Becoming an authorised service agent involves considerably more than adding another manufacturer to an inspection list.

Velocity Safety has invested thousands of pounds in the training, tooling, servicing jigs and spare parts needed to support G-Force equipment properly.

This gives our technicians access to the procedures and technical information required when servicing applicable G-Force fall arrest blocks.

It also expands the range of fall-protection equipment we can supply directly to customers.

Why Manufacturer-Authorised Servicing Matters

An external inspection can identify visible damage, deterioration, missing labels and problems with the lifeline, connectors or casing.

However, servicing work may also require:

• Manufacturer-specific training
• Specialist jigs and tooling
• Access to the correct service manuals
• Specified procedures and torque settings
• Suitable replacement components and spare parts
• Internal examination where required

Without these resources, a provider may only be completing an external examination before attaching a new inspection tag.

“A coloured inspection tag does not prove that lifting equipment is correctly marked, traceable or safe to use.”

Lifting equipment can appear serviceable while its identification plate, load tag or other essential markings are missing, illegible or incomplete.

This is not a minor paperwork issue.

Under Regulation 7 of the Lifting Operations and Lifting Equipment Regulations 1998 (LOLER), lifting equipment and accessories must carry—or be supported by—clear information about their safe working load and the characteristics necessary for safe use.

If workers cannot establish what an item can safely lift, which configuration the stated capacity applies to or whether it is intended for lifting people, it should not simply receive a new coloured tag and return to service.

Learn more about our LOLER thorough examinations of lifting equipment and accessories.

Jump to:

What Does LOLER Regulation 7 Require?

Regulation 7 addresses the marking of lifting equipment used at work.

Its purpose is to ensure operators can identify the equipment’s safe capacity, important limitations and whether it is suitable for the proposed lifting operation.

Regulation 7 builds upon PUWER Regulation 23, which requires work equipment to carry clearly visible health and safety markings where appropriate.

Correct marking is therefore part of the equipment’s safe-use system—not an optional administrative detail.

Safe Working Load Markings

The safe working load is the maximum load that equipment can safely lift in its stated configuration and operating conditions.

For equipment with one fixed capacity, the actual SWL should normally be clearly marked on the item.

Examples include:

• Overhead cranes
• Hoists and winches
• Shackles
• Single-leg slings
• Lifting beams with one fixed arrangement
• Some forklift trucks and lifting attachments

Terms such as rated capacity or working load limit (WLL) may also appear on equipment and manufacturer documentation. The terminology must be interpreted in the context of the equipment, its instructions and the proposed lifting arrangement.

Workers should never estimate capacity from the physical size of a chain, hook or shackle. Two visually similar components may have different grades, specifications and load ratings.

Where it is impractical to mark the numerical value directly, HSE guidance permits an appropriate coding or labelling system that allows the user to determine the SWL.

That system must remain understandable, visible and suitable for the working environment.

What If the Safe Working Load Changes?

Some lifting equipment does not have one fixed capacity.

Its SWL may change according to:

• Operating radius
• Boom or jib position
• Use of outriggers
• Attachments fitted to the machine
• Number of sling legs in use
• Sling angle or method of attachment
• Available lifting points on a beam
• Other manufacturer-defined configurations

In these circumstances, marking the equipment with only its highest possible capacity can be dangerously misleading.

The applicable capacities may be communicated using:

• A marked plate
• A load chart
• A rated-capacity indicator
• A durable certificate kept with the machinery
• Another system that makes the correct information readily available to the operator

The operator must be able to identify the correct SWL for the configuration actually being used—not merely the maximum capacity the equipment can achieve under different conditions.

If reliable information is unavailable for a particular configuration, the capacity must not be guessed.

HSE guidance states that any derating should be undertaken by a competent person using appropriate information from the manufacturer or supplier.

What Must Be Marked on Lifting Accessories?

LOLER defines an accessory for lifting as equipment used to attach a load to lifting machinery.

Examples include:

• Chain slings
• Wire-rope and textile slings
• Shackles
• Hooks
• Removable eyebolts
• Plate clamps
• Lifting magnets
• Vacuum lifters
• Lifting beams and spreader beams

In addition to the SWL, an accessory may need to communicate other characteristics affecting its safe use.

Depending on the equipment and applicable manufacturer requirements or standards, these can include:

• The configurations in which it can be used
• Capacity at different sling angles
• The accessory’s own weight where significant
• Permitted plate thickness for a lifting clamp
• Compatibility with a particular machine or assembly
• Limitations involving heat, chemicals or corrosive environments
• Manufacturer, grade, size or other product information
• Information needed to identify the correct instructions and records

Where several accessories form a permanent lifting assembly, the complete assembly should be marked to communicate its relevant safety characteristics.

A collection of individually rated components does not automatically create an assembly with the same capacity as its strongest component.

Do Lifting Accessories Need an Identification or Serial Number?

Regulation 7 does not state that every lifting accessory must carry a serial number in those exact words.

However, it does require accessories to be marked so that the characteristics necessary for their safe use can be identified.

Separate product-supply, manufacturer and equipment-standard requirements can also require identifying information such as a type, batch, serial number or another traceability reference.

In practical equipment management, a unique ID allows the correct item to be connected to:

• Manufacturer information
• Its Declaration of Conformity where applicable
• Instructions and technical information
• The equipment register
• Previous thorough examination reports
• Repairs, defects and maintenance history
• The next examination due date

This becomes particularly important where a business holds several visually identical slings, shackles or hoists.

Without reliable identification, it may be impossible to demonstrate which item was examined or whether the available paperwork relates to the equipment in front of the user.

How Should Equipment for Lifting People Be Marked?

Equipment designed for lifting people must be clearly marked to show that it is intended for this purpose.

The carrier should also display:

• Its safe working load
• The maximum number of people it can carry
• Any other limitations required for its safe use

Examples can include passenger lifts, personnel baskets, patient hoists and other equipment specifically designed to lift or lower people.

Where lifting equipment is not designed for lifting people but might mistakenly be used in that way, it must be clearly marked to show that it is not intended for lifting persons.

This requirement does not mean that every item of load-lifting equipment needs an identical warning. It applies where incorrect use for lifting people is reasonably foreseeable.

What Should You Do If a Load Tag or Marking Is Missing?

A missing, detached, damaged or illegible marking should be treated as a safety concern.

The appropriate response will depend on the equipment and whether its identity and capacity can be reliably established.

A sensible process includes:

1. Stop using the item where its safe capacity or suitability cannot be confirmed.
2. Segregate or quarantine it so that another worker does not return it to use.
3. Do not estimate the SWL from appearance, dimensions or another similar item.
4. Check the available records, including manufacturer information, declarations, certificates and previous examination reports.
5. Confirm whether the item can be positively identified using reliable markings or documented information.
6. Arrange assessment by a competent person where its status remains uncertain.
7. Only replace a tag or marking when the information it contains has been properly verified.

Some marking problems can be rectified once the equipment and its rating have been confirmed.

Where identity, grade or capacity cannot be established, applying a new tag with an assumed SWL is not a safe remedy.

Are Markings Checked During a LOLER Thorough Examination?

Yes. Markings, identification and traceability form an important part of a thorough examination.

A competent person may consider:

• Whether the SWL is present and legible
• Whether the stated capacity is consistent with the equipment and available information
• Whether different configurations are adequately addressed
• Whether lifting accessories can be identified and linked to the correct records
• Whether manufacturer or product information is missing
• Whether required warnings or limitations are present
• Whether tags, plates or labels are secure and sufficiently durable
• Whether the equipment has been incorrectly or misleadingly marked

Marking is only one part of the examination.

The competent person must also assess the equipment’s condition and look for defects such as wear, deformation, cracking, corrosion, damaged components and other deterioration that could affect safe use.

A clear SWL plate does not prove that equipment remains safe, just as a current inspection colour does not correct missing safety information.

Velocity Safety carries out thorough examinations of lifting equipment and accessories, including asset identification, marking checks, defect reporting and traceable digital records.

For an example of why close physical examination matters, see our guide to surface rust on lifting chains.

A Quick Lifting Equipment Marking Check

Take a look at the chain slings, shackles, hoists and lifting attachments currently in use on your site.

For each item, ask:

• Can the safe working load be clearly identified?
• Is the marking legible without having to guess worn characters?
• Can the item be matched to the correct examination report?
• Are capacities provided for every permitted configuration?
• Are important limitations or compatibility requirements available?
• Is equipment intended for lifting people identified correctly?
• Are tags and plates secure, durable and appropriate for the environment?
• Does the physical equipment match the description in its records?

If the answer to any of these questions is no, the issue deserves more than a quick replacement sticker.

Frequently Asked Questions

Does all lifting equipment need a safe working load marking?

Machinery and accessories used for lifting loads at work must clearly indicate their safe working load under LOLER Regulation 7. Where a numerical marking cannot be placed directly on the equipment, an appropriate system must allow the user to determine its SWL reliably.

What if lifting equipment has more than one safe working load?

Where capacity changes according to configuration, the SWL for each permitted configuration must be marked or made readily available to the operator. This may be provided through a load chart, plate, indicator or durable accompanying information.

Is a LOLER inspection tag a legal certificate?

No. A tag can help communicate an item’s status or next examination date, but it is not the thorough examination report and does not replace required safety markings. The formal report must contain the applicable information required under LOLER.

Is colour coding enough to comply with LOLER?

Colour coding can form part of a system used to identify the SWL where direct numerical marking is impractical. The system must enable users to determine the correct capacity reliably. A colour used only to indicate an examination period is not a substitute for SWL information.

Can a missing lifting-equipment tag simply be replaced?

Only when the equipment’s identity, specification and capacity can be reliably verified. A replacement tag must not be based on appearance, assumption or the rating of a similar item. Equipment should be removed from use where its safe capacity cannot be established.

Do shackles and chain slings need individual identification?

The exact marking requirements depend on the equipment, manufacturer information and applicable product standard. Regulation 7 requires the necessary safe-use characteristics to be identifiable, while effective individual identification allows each item to be matched to its examination records and supporting information.

Does correct marking prove that lifting equipment is safe?

No. Correct marking is essential, but equipment can still be unsafe because of wear, corrosion, cracking, deformation, incorrect assembly or other defects. It must also receive the required pre-use checks, maintenance and thorough examinations.

How often should lifting accessories be thoroughly examined?

Lifting accessories are generally thoroughly examined at least every six months, unless a competent person’s written examination scheme specifies a different appropriate interval. Equipment used to lift people is also generally subject to a maximum six-month interval. Other lifting equipment is generally examined at least every 12 months unless an examination scheme applies.

Can lifting equipment fail a thorough examination because of missing markings?

Yes. Missing, illegible or unreliable markings can prevent the competent person from confirming the equipment’s capacity, identity or safe-use limitations. Read more about why even brand-new lifting equipment can fail a thorough examination.
