What is the purpose of a PUWER inspection? Its fundamental purpose is to establish whether work equipment can be operated, adjusted and maintained safely, and to identify deterioration or defects before they create a health and safety risk.
That concise answer needs an important qualification. PUWER does not require every item of work equipment to receive an identical formal inspection every year. The need, scope and frequency of inspection depend on the equipment, how its safety is affected by installation, the deterioration it may experience and the risks that could result.
A PUWER inspection is also not a substitute for proper equipment selection, guarding, maintenance, training or safe operating procedures. Inspection is one part of a wider system for keeping work equipment safe.
What is the purpose of a PUWER inspection?
The purpose of a PUWER inspection is to detect safety-related problems in work equipment so that they can be addressed before the equipment causes harm.
According to the Health and Safety Executive, an inspection should determine whether equipment can be operated, adjusted and maintained safely. It should identify deterioration and enable it to be remedied before it results in a health and safety risk.
Depending on the equipment and circumstances, an inspection may help identify:
-
Damage, wear or corrosion
-
Defective or missing guards
-
Safety devices that do not operate correctly
-
Damaged controls or emergency stops
-
Unsafe electrical, hydraulic or pneumatic components
-
Instability or insecure installation
-
Defective brakes, steering or visibility aids
-
Missing warnings or illegible safety markings
-
Deterioration following intensive use or harsh conditions
-
Problems caused by modification, relocation or repair
The inspection should focus on matters that affect safety. It should not become a generic paperwork exercise in which every item receives the same checklist regardless of its design, condition or use.
What is PUWER?
PUWER stands for the Provision and Use of Work Equipment Regulations 1998.
The Regulations place duties on employers, self-employed people and organisations that own, provide, operate or control work equipment. Responsibilities can also apply where employees use equipment that the employer does not own, including equipment provided by an employee for use at work.
The definition of work equipment is deliberately broad. It includes machinery, appliances, apparatus, tools and installations used at work.
Examples can include:
-
Production machinery
-
Machine tools
-
Forklift trucks and other mobile plant
-
Workshop equipment
-
Compressors
-
Conveyors
-
Vehicle ramps
-
Ladders
-
Drills and hand tools
-
Office equipment
-
Cleaning machinery
-
Agricultural machinery
-
Equipment hired or leased for work
Using work equipment includes more than normal operation. It can include starting, stopping, programming, setting, transporting, repairing, modifying, maintaining, servicing and cleaning it.
PUWER requires work equipment to be suitable for its intended use, maintained in a safe condition and accompanied by suitable protective measures. Users, supervisors and managers must receive adequate information, instruction and training.
The HSE PUWER overview provides a useful summary of these wider duties.
Does every item of work equipment require a formal inspection?
No. Not every item requires a detailed, recorded inspection simply because it is used at work.
For some low-risk equipment, a straightforward visual check before use may be sufficient. Other equipment may require regular recorded inspections, testing or partial dismantling because a defect or deterioration could create a significant risk.
The correct approach should be based on risk rather than applying one inspection format to everything.
Factors affecting the need for formal inspection include:
-
Whether safety depends on correct installation
-
Whether the equipment deteriorates through use or age
-
The severity of harm that a failure could cause
-
The environment in which it is used
-
The equipment’s complexity
-
Its maintenance and defect history
-
Manufacturer’s recommendations
-
Relevant industry guidance
-
Whether it has been modified, moved or damaged
-
The competence needed to identify safety-critical defects
Pre-use checks remain valuable, but they are not automatically equivalent to a formal inspection under regulation 6 of PUWER.
When is a PUWER inspection required?
Regulation 6 of PUWER identifies three principal circumstances in which inspection is required.
When safety depends on installation conditions
Where equipment safety depends on how it is installed, it must be inspected after installation and before it is first put into use.
It must also be inspected after assembly at a new site or location where its safety depends on the new installation conditions.
Examples could include equipment that requires:
-
Secure anchoring
-
Levelling or alignment
-
Connection to extraction or other protective systems
-
Correct assembly of guards or interlocks
-
Integration with another machine
-
Stabilisation or support
-
Safe connection to power or stored-energy systems
The inspection should confirm that the equipment has been installed correctly and can operate safely.
When deterioration could cause danger
Work equipment exposed to conditions that cause deterioration must be inspected at suitable intervals where that deterioration could lead to a dangerous situation.
Deterioration may result from:
-
Normal wear
-
Intensive or repeated operation
-
Vibration
-
Corrosion
-
Weather exposure
-
Heat or cold
-
Dust or contamination
-
Chemicals
-
Moisture
-
Impact or abrasion
-
Ageing of components
-
Repeated assembly and dismantling
The interval should be short enough to detect foreseeable deterioration before it creates unacceptable risk.
After exceptional circumstances
Equipment should be inspected after exceptional circumstances that are liable to jeopardise its safety.
Examples can include:
-
Major modification
-
Known or suspected serious damage
-
Collision or overturning
-
Failure of a safety device
-
Substantial change in use
-
Relocation affecting installation
-
A prolonged period out of use
-
Exposure to flooding, fire or severe weather
-
Significant repair to a safety-critical component
The equipment should not simply remain in service until its next planned inspection if an event may have compromised its safety.
The precise inspection duties are set out in regulation 6 of PUWER.
What should a PUWER inspection cover?
The inspection scope should reflect the equipment, its use, its environment and the ways in which it could become unsafe.
There is no single checklist that is suitable for every type of work equipment. A small portable tool and a complex production machine do not present the same hazards or require the same inspection depth.
A PUWER inspection might consider the following areas where they are relevant.
General condition
-
Damage, distortion, corrosion or excessive wear
-
Loose, missing or unsuitable components
-
Evidence of leaks or overheating
-
Unusual movement, vibration or noise
-
Contamination affecting safe operation
-
Deterioration of access platforms or supporting structures
Guards and protective devices
-
Fixed guards are present, secure and suitable
-
Interlocked guards operate as intended
-
Safety devices have not been bypassed or defeated
-
Openings and safety distances remain appropriate
-
Access to dangerous parts is adequately prevented
-
Protective devices fail to a safe condition where required
Controls and emergency functions
-
Start and stop controls operate correctly
-
Controls are clearly identifiable
-
Emergency stops work as intended
-
Restart after an interruption does not create danger
-
Control locations allow safe operation
-
Unintended or unauthorised operation is prevented where necessary
Isolation and stored energy
-
Equipment can be isolated from its energy sources
-
Isolation devices are identifiable and accessible
-
Electrical, hydraulic, pneumatic, mechanical and gravitational energy can be controlled
-
Maintenance can be completed without avoidable exposure to danger
-
Residual or stored energy is addressed
Stability and installation
-
Equipment remains securely installed
-
Anchors, supports and fastenings are in suitable condition
-
Levelling and alignment remain acceptable
-
Pipes, cables and connections do not create additional hazards
-
Changes to the surrounding workplace have not compromised safe use
Mobile work equipment
-
Brakes and steering operate effectively
-
Tyres and wheels remain in suitable condition
-
Visibility aids, mirrors, cameras and lights function correctly
-
Restraints and rollover protection remain serviceable
-
Audible and visual warning devices operate
-
Measures protecting pedestrians remain appropriate
Information and markings
-
Safety notices remain legible
-
Control markings are clear
-
Safe operating information is available
-
Rated capacities and limitations are displayed where required
-
Inspection or defect labels accurately reflect equipment status
Not every inspection requires testing or dismantling. However, these may be necessary where a visual inspection alone cannot establish the condition of a safety-critical part.
Is a PUWER inspection the same as a PUWER assessment?
The expressions are often used interchangeably, but they can describe different scopes of work.
An inspection under regulation 6 is concerned with the safety of equipment following installation, deterioration or exceptional circumstances.
A broader PUWER assessment may examine the equipment and how it is managed against a wider range of PUWER duties, including:
-
Suitability for the intended task
-
Maintenance arrangements
-
Specific risks and restrictions on use
-
Information and instructions
-
Operator and supervisor training
-
Dangerous parts and guarding
-
Protection from ejected materials
-
Temperature risks
-
Starting and stopping controls
-
Emergency controls
-
Isolation
-
Stability
-
Lighting
-
Markings and warnings
-
Mobile work equipment requirements
A business requesting a “PUWER inspection” should therefore clarify whether it needs a regulation 6 inspection, a broader compliance assessment or both.
Passing an inspection of equipment condition does not, by itself, prove that every applicable PUWER duty has been satisfied.
How often should PUWER inspections be carried out?
PUWER does not impose a universal 12-month inspection interval for all work equipment.
The inspection frequency should be determined through risk assessment. It should account for:
-
Manufacturer’s recommendations
-
The equipment’s design and age
-
Frequency and intensity of use
-
The operating environment
-
Foreseeable deterioration
-
Previous inspection findings
-
Maintenance and repair history
-
Relevant industry guidance
-
The consequences of a defect or failure
-
The effectiveness of pre-use checks
Inspection intervals may range from pre-use or daily checks to weekly, monthly, quarterly or longer periods. Different safety-critical parts of the same machine may also need attention at different intervals.
An organisation may review its intervals using reliable inspection history. Where negligible deterioration is consistently found, an interval may sometimes be increased if the risk assessment supports that decision. Where inspections reveal deterioration that could become dangerous between visits, the interval should be shortened.
A convenient annual date should not be adopted without considering whether it is suitable for the actual risk.
Who can carry out a PUWER inspection?
A PUWER inspection should be carried out by someone with sufficient knowledge and experience to identify relevant defects and respond appropriately.
The person needs to understand:
-
What parts or functions require inspection
-
What defects or deterioration to look for
-
Which findings affect safety
-
What action is required when a defect is found
-
When specialist assessment or testing is necessary
-
The limits of their own competence
The level of competence should be proportionate to the equipment and inspection.
A trained operator may be competent to complete defined pre-use checks. An experienced in-house engineer may be competent to inspect familiar machinery. Complex plant, unfamiliar equipment or specialist safety systems may require an independent person with more specific knowledge and experience.
PUWER does not require every inspection to be outsourced. However, an organisation should not allocate the task solely because someone is available or has general mechanical experience.
Independent support can be particularly valuable where:
-
Internal competence is limited
-
Equipment is complex or unfamiliar
-
The adequacy of existing controls is uncertain
-
A significant modification has been made
-
Previous inspections have been inconsistent
-
An impartial compliance review is needed
-
A customer, insurer or procurement process requires evidence
Safe-Lee provides independent PUWER inspections for plant, machinery and work equipment.
Do PUWER inspection results need to be recorded?
Where an inspection is required under regulation 6, the result should be recorded and retained at least until the next inspection of that equipment has been completed.
Records may be electronic rather than paper, provided they are secure, retrievable and available when required.
A useful inspection record should make clear:
-
Which item was inspected
-
Where it was located
-
The date of inspection
-
The inspection scope
-
Who completed it
-
Defects or concerns identified
-
The action required
-
Any restriction placed on use
-
The remedial deadline
-
The next inspection date or review point
-
Confirmation that remedial work was completed
The record needs to demonstrate what was actually inspected. A generic sticker showing a date may help with equipment control, but it may not provide adequate detail for complex equipment or significant findings.
Where equipment requiring inspection leaves one undertaking for use elsewhere, physical evidence of the last inspection should accompany it. This is particularly relevant to hired, leased or mobile equipment.
What happens when a defect is found?
Finding a defect is not the end of the process. The significance of the defect must be assessed and suitable action taken.
Depending on the risk, action may include:
-
Removing the equipment from use immediately
-
Isolating or locking it off
-
Applying a clear prohibition or quarantine label
-
Restricting how the equipment may be used
-
Arranging repair or replacement
-
Obtaining specialist assessment
-
Re-inspecting after remedial work
-
Reviewing similar equipment for the same issue
-
Changing the maintenance or inspection interval
-
Updating the risk assessment and safe system of work
A cosmetic issue and a failed safety interlock do not require the same response. The system should distinguish between observations, defects requiring planned correction and defects requiring immediate withdrawal.
Equipment should not be returned to service merely because a repair has been attempted. Where safety depends on the repair, suitable verification or re-inspection may be necessary.
Repeated defects should also trigger a wider review. They may indicate unsuitable equipment, poor maintenance, misuse, inadequate training, an unsuitable environment or an ineffective inspection interval.
PUWER inspections, maintenance and risk assessments
Inspection, maintenance and risk assessment are connected, but they are not interchangeable.
Inspection
Inspection identifies safety-related defects, deterioration or installation problems at a particular point in time.
Maintenance
Maintenance keeps equipment in an efficient state, efficient working order and good repair. It can include servicing, lubrication, adjustment, replacement and repair.
A maintenance visit is not automatically a PUWER inspection unless the required safety-related inspection is deliberately completed by a competent person and appropriately recorded.
Risk assessment
Risk assessment determines how people could be harmed and what precautions are required. It helps establish whether inspection is needed, what it should cover and how often it should occur.
Pre-use checks
Pre-use checks identify obvious problems before operation. They can often be completed by a trained user, but they do not replace more detailed inspection where one is required.
An effective equipment safety system connects all four activities. Inspection findings should inform maintenance and risk assessment, while maintenance history should influence future inspection scope and frequency.
What is the difference between PUWER and LOLER?
PUWER applies broadly to work equipment. LOLER applies specifically to lifting equipment and lifting operations.
An item such as a forklift truck, crane, hoist or vehicle lift may be subject to both sets of Regulations.
PUWER may require attention to:
-
Suitability
-
Maintenance
-
General equipment inspection
-
Controls
-
Guarding
-
Stability
-
Training
-
Information
-
Mobile equipment risks
LOLER adds specific requirements relating to matters such as:
-
Strength and stability for lifting
-
Positioning and installation
-
Safe working loads
-
Organisation of lifting operations
-
Thorough examination
-
Reports and defects
A PUWER inspection does not replace a required LOLER thorough examination. Likewise, a current LOLER report does not demonstrate compliance with every applicable PUWER duty.
Safe-Lee’s guide to how often lifting equipment should be inspected under LOLER explains the separate six-month, 12-month and examination-scheme arrangements.
If the final URL of that article differs, update the link before publishing this post.
Does conformity marking mean no PUWER inspection is needed?
No. Appropriate conformity marking and a Declaration of Conformity relate to product supply requirements. They do not remove the employer’s duties under PUWER.
Before using new equipment, the dutyholder should still consider:
-
Whether it is suitable for the intended task
-
Whether it is safe in the actual workplace
-
Whether installation affects safety
-
Whether instructions are available and understood
-
Whether guarding and controls are suitable
-
Whether users have received adequate training
-
Whether additional inspection is required
-
Whether workplace integration has introduced new risks
Conformity marking should not be treated as a substitute for checking that equipment is suitable and safe in its intended working environment.
Common PUWER inspection mistakes
Assuming every machine needs an annual certificate
PUWER does not establish one annual interval for every item. Frequency should be justified by risk.
Using the same checklist for unrelated equipment
A checklist should reflect the equipment’s safety-critical features, likely deterioration and operating environment.
Confusing inspection with maintenance
Servicing equipment does not necessarily confirm that guards, controls and other safety measures meet the required standard.
Inspecting equipment but ignoring how it is used
An item can be mechanically sound yet unsuitable for the task, operated by untrained people or used without adequate controls.
Treating the report as the end of the process
Defects must be assessed, controlled and remedied. Completion should be recorded where appropriate.
Relying only on a sticker
A sticker can show inspection status but may not provide sufficient evidence of scope, findings and required action.
Forgetting hired or employee-owned equipment
PUWER responsibilities are not limited to equipment owned by the employer.
Over-inspecting low-risk equipment
Excessive paperwork can encourage superficial tick-box inspections. The effort should focus on what is necessary for safety.
Failing to inspect after exceptional events
Damage, modification, relocation or a substantial change in use may require inspection before the normal due date.
Frequently asked questions
Is a PUWER inspection a legal requirement?
Inspection is legally required in the circumstances described by regulation 6, including where equipment safety depends on installation and where deterioration could cause dangerous situations. Not every item requires the same type of formal inspection.
Does PUWER require annual inspections?
No universal annual period applies. The interval should be determined through risk assessment, manufacturer’s recommendations, industry guidance and experience of the equipment.
Does PUWER apply to old machinery?
Yes. PUWER applies to work equipment regardless of whether it was acquired recently or has been in service for many years. Older equipment may require careful assessment because its original safeguards, controls or documentation may differ from current expectations.
Can PUWER inspections be completed in-house?
Yes, where the person has sufficient knowledge and experience for the equipment and inspection involved. More complex or unfamiliar equipment may require specialist support.
Is a PUWER assessment the same as a risk assessment?
No. A PUWER assessment may examine equipment and its management against specific duties within PUWER. A risk assessment considers the risks arising from the work activity and the precautions needed. The two should inform each other.
Do hand tools come under PUWER?
Hand tools used at work can fall within PUWER’s broad definition of work equipment. The proportionate control may be a simple pre-use check, suitable maintenance and replacement when damaged rather than a detailed periodic inspection.
Does a PUWER inspection cover electrical safety?
It may identify visible electrical defects and safety-related issues relevant to the equipment, but it does not replace duties under the Electricity at Work Regulations or any specialist electrical inspection and testing that may be required.
Does a PUWER inspection cover lifting equipment?
PUWER can apply to lifting equipment, but LOLER may impose additional requirements, including thorough examination. Both regimes should be considered.
Is a PUWER inspection certificate enough to prove compliance?
No single certificate proves compliance with every aspect of PUWER. Compliance also depends on suitability, maintenance, guarding, controls, information, training and how the equipment is actually used.
Arranging an independent PUWER inspection
Before arranging an inspection or assessment, it helps to compile:
-
An equipment register
-
Manufacturer’s instructions
-
Previous inspection records
-
Maintenance and repair history
-
Details of modifications
-
Current risk assessments
-
Safe operating procedures
-
Training records
-
Information about defects or unusual events
-
Details of how and where the equipment is used
The required scope should then be agreed. This avoids uncertainty about whether the work covers a regulation 6 condition inspection, a broader PUWER compliance assessment or both.
