MEWP Risk Assessment & Pre-Use Inspection Checklist UK
Mobile Elevated Work Platforms — MEWPs — are among the most versatile and widely used access equipment in UK construction and maintenance. They are also, when used incorrectly, among the most dangerous. Overturning incidents, entrapment, falls from the platform, and being struck by a MEWP are all recorded in HSE fatality statistics.
A MEWP risk assessment is a legal requirement before any MEWP operation begins. This guide covers what that assessment must include, what IPAF training is required, how LOLER inspection works for MEWPs, and what your pre-use checklist should cover.
What is a MEWP?
A Mobile Elevated Work Platform is any powered device designed to move people to height to carry out work. The category covers a wide range of equipment:
Scissor lifts — vertically rising platforms on a scissored mechanical support. Stable and spacious, predominantly used on flat, firm surfaces. Available in electric (indoor) and diesel (outdoor) variants.
Boom lifts — articulated or telescopic booms with a basket at the end. Much greater reach and outreach than scissor lifts, able to reach over obstacles and work at angles. Higher overturning risk due to the extended boom.
Truck-mounted platforms — cherry pickers mounted on road vehicles. Used extensively in utilities, arboriculture, and streetworks. Can reach significant heights.
Spider lifts — compact, track-mounted MEWPs capable of operating on uneven terrain and fitting through standard doorways. Increasingly common in building services and maintenance.
Personnel carriers — smaller MEWPs designed for lower-level work in confined spaces.
The type of MEWP used must be appropriate to the task, the working height, the outreach required, and the ground conditions. Selecting the wrong MEWP type is a common cause of incidents.
IPAF and operator competency
IPAF — the International Powered Access Federation — operates the PAL (Powered Access Licence) scheme, which is the recognised standard for MEWP operator competency in the UK.
IPAF training covers the safe operation of specific MEWP categories. The categories relevant to most construction and maintenance work are:
- 1a — Static vertical (scissor lifts)
- 1b — Static boom (boom lifts used from a fixed position)
- 3a — Mobile vertical (scissor lifts driven at height)
- 3b — Mobile boom (boom lifts driven in any configuration)
Operators need to be trained and hold a valid PAL card for the specific category of MEWP they are using. Using a boom lift on a PAL card trained only for scissor lifts is not compliant.
The PAL card is typically valid for five years. Refresher training is required on renewal. Most principal contractors will not permit MEWP operation without a valid PAL card.
Your MEWP risk assessment must confirm that all operators are IPAF-trained for the specific category of MEWP being used.
LOLER and MEWP inspections
The Lifting Operations and Lifting Equipment Regulations 1998 (LOLER) apply to MEWPs because they are equipment used to lift people. Under LOLER, MEWPs must be:
Thoroughly examined by a competent person at intervals not exceeding six months, or in accordance with an examination scheme drawn up by a competent person. The thorough examination must be documented and the record retained.
Pre-use inspected before each day's use or each new operational period. This pre-use check is carried out by the operator and covers the mechanical, hydraulic, and safety systems of the MEWP.
Inspected after any significant event — impact, overloading, or any event that may have affected the structural or mechanical integrity of the machine.
The LOLER thorough examination is separate from the routine service and maintenance carried out by the equipment supplier. The examination record — often called a Form F or similar — must accompany the MEWP and be available on site.
When hiring a MEWP, always request the current LOLER examination certificate before the machine is used on site. An unexamined MEWP must not be put into service.
MEWP pre-use inspection checklist
Before every operational period, the MEWP operator must carry out a pre-use inspection. This is not a lengthy process — a thorough pre-use check takes approximately 10 minutes — but it must cover the following:
Ground conditions assessment
- Is the ground firm, level, and capable of supporting the MEWP's outrigger or wheel loads?
- Are there any underground voids, drains, or services that could collapse under load?
- Is there adequate clearance for outriggers to be fully deployed?
Overhead and surrounding hazards
- Are there overhead power lines within the working envelope?
- Are there overhead obstructions that could cause entrapment?
- Is there sufficient clearance for the MEWP to operate without risk of contact?
Mechanical and hydraulic checks
- Fluid levels (hydraulic oil, engine oil, coolant, fuel)
- No visible leaks from hydraulic hoses or connections
- Tyres inflated to correct pressure (or tracks in good condition)
- All pins, fasteners, and structural connections in place and undamaged
Electrical checks (electric MEWPs)
- Battery charge level adequate for the planned operation
- Charging leads stowed and not damaged
Platform and safety systems
- Platform guard rails in place and undamaged
- Platform floor clean and non-slip
- Emergency lowering system present and functional
- Harness anchor points present (where a harness is required)
- Controls operating correctly from both ground and platform stations
- Emergency stop functional
- Horn and lights operational
Documentation
- LOLER examination certificate present and within date
- Operator PAL card valid for this MEWP category
Any defect identified during the pre-use check must be reported immediately and the MEWP must not be used until the defect is rectified.
Key hazards in the MEWP risk assessment
A MEWP risk assessment must go beyond the pre-use checklist to address the operational hazards specific to the task being carried out:
Overturning — the leading cause of serious MEWP incidents. Caused by inadequate ground conditions, exceeding the rated capacity, operating with outriggers not fully deployed, driving on slopes beyond the rated gradient, or boom extension in configurations that exceed stability limits. The risk assessment must specify ground condition requirements and operating limits.
Overhead power lines — contact with overhead lines is potentially fatal and has caused multiple fatalities in UK construction. The risk assessment must identify whether power lines are present in the working area, their voltage, and the minimum approach distance. Working near overhead lines requires specific controls and, where necessary, liaison with the network operator.
Entrapment — operators have been fatally crushed between the MEWP platform and overhead structures. The risk assessment must assess the risk of entrapment specific to the working environment and specify controls — including the use of secondary guarding devices where the risk is high.
Falls from the platform — operators must be secured by a harness attached to the anchor point within the platform when operating a boom lift. For scissor lifts, the requirement depends on the risk assessment, but a harness is recommended where there is a risk of the platform moving unexpectedly.
Transporting the MEWP — moving a MEWP on public roads or between sites introduces specific risks: securing the machine to the transport vehicle, ensuring the vehicle has the correct rating, and managing the risk of the MEWP moving in transit.
