2.3 Provision and Use of Work Equipment Regulations 1998 (PUWER)

The Architecture and Scope of PUWER 1998

The Provision and Use of Work Equipment Regulations 1998 (PUWER, Statutory Instrument 1998 No. 2306) establish comprehensive legal standards for all machinery, appliances, apparatus, tools, and installations provided for use at work in Great Britain. Unlike LOLER, which focuses strictly on lifting operations, PUWER applies universally—from a simple utility knife to an 80-tonne mobile industrial MEWP.

The Legal Symbiosis Between PUWER and LOLER

When operating a MEWP, PUWER and LOLER operate concurrently. PUWER governs the non-lifting mechanical integrity, electrical systems, emergency stop buttons, brakes, drive gear, wheels, tyres, operator training, maintenance, and machine suitability. LOLER layers over PUWER to govern the specific lifting mechanisms, load-holding valves, boom extension chains, platform load sensors, and 6-month statutory thorough examinations. Compliance with LOLER alone does not satisfy PUWER; both statutory instruments must be met simultaneously.

Regulation 4: Suitability of Work Equipment

Regulation 4(1) requires that work equipment be constructed or adapted so as to be suitable for the purpose for which it is used or provided. Regulation 4(2) mandates that employers have regard to the specific working conditions and risks in the workplace when selecting work equipment.

Key MEWP Selection Criteria Under Regulation 4

Selecting an inappropriate machine violates Regulation 4 even if the machine is brand new and mechanically flawless. When matching a MEWP to a task, duty holders must evaluate:

1. Nature of the Task and Working Envelope: Maximum working height, required horizontal outreach, and negative reach (below-ground or below-quay work). Operating a machine at its absolute kinematic limit where operators must lean outward breaches Regulation 4.
2. Platform Load Capacity: The combined weight of occupants, hand tools, replacement cladding panels, or pipework must not exceed the manufacturer's Safe Working Load (SWL).
3. Chassis Type and Terrain: Operating a narrow-chassis, two-wheel-drive electric scissor lift designed for indoor concrete slabs on uncompacted, muddy construction fill violates Regulation 4. On uneven ground, Regulation 4 points to a rough-terrain four-wheel-drive machine with oscillating axles and high ground clearance.
4. Environmental and Atmospheric Conditions: Internal work requires clean electric or bi-fuel units to eliminate toxic exhaust emissions (carbon monoxide, nitrogen oxides) and excessive noise. Flammable atmospheres (such as chemical refineries or paint spray booths) legally demand specialised ATEX-rated flameproof MEWPs.
5. Floor and Slab Loading Limits: Suspended floors, computer rooms, multi-story car parks, and mezzanine decks have maximum permissible point load and uniform distributed load capacities. Heavy machines risk punching through structural slabs.

Regulations 5 and 6: Maintenance and Inspection Regimes

Regulation 5: Maintenance Standards

Regulation 5 requires every employer to ensure that work equipment is maintained in an efficient state, in efficient working order, and in good repair. For MEWPs, maintenance must follow the original equipment manufacturer (OEM) maintenance manual:

• Preventive Maintenance: Scheduled servicing based on engine/motor hours or calendar intervals (e.g. 50-hour, 250-hour, 500-hour, and annual services).
• Lubrication and Hydraulics: Fluid replacement, filter changes, hydraulic hose inspections, and chassis/boom grease point servicing.
• Maintenance Logs: Regulation 5(2) requires that where equipment has a maintenance log, the log must be kept up to date. While keeping a log is not universally mandated for basic hand tools, it is practically essential for complex access plant to prove compliance in any HSE audit or court inquiry.

Regulation 6: Operational Inspections

Regulation 6 mandates that where work equipment is exposed to conditions causing deterioration liable to result in dangerous situations, it must be inspected by a competent person at suitable intervals.

In practice, the inspection regime that satisfies Regulation 6 (together with LOLER Regulation 9(3)(b) inspections between thorough examinations) includes:

• Pre-Use Checks (Pre-Start Walk-Around): Conducted by the operator prior to the start of every work shift. The check involves a visual walk-around of structural steelwork, weld seams, pins, hydraulic hoses, and wheels/tyres, followed by a functional test of all controls, limit switches, horn, emergency stop buttons, and emergency lowering systems from both the ground control station and the platform control station.
• Periodic Inspections: Weekly or monthly documented physical inspections performed by a competent site plant fitter or trained supervisor, recorded in the site plant register.

Regulations 8 and 9: Information, Instructions, and Operator Training

Regulation 8: Information and Written Instructions

Employers must provide all persons who use, supervise, or manage work equipment with adequate health and safety information and written instructions. This requires that:

• Operators have immediate access to the manufacturer's Operator Manual in the machine's dedicated container.
• Safety warning decals, load charts, slope limits, and emergency descent diagrams on the machine are intact, clean, and legible in the working language of the operator.

Regulation 9: Operator Competence and Training

Regulation 9(1) is the core statutory requirement for operator training in the UK:

"Every employer shall ensure that all persons who use work equipment have received adequate training for purposes of health and safety, including training in the methods which may be adopted when using the work equipment, any risks which such use may entail and precautions to be taken."

Regulation 9(2) extends this exact training requirement to those who supervise or manage workers using the equipment. This is the legal origin of the requirement for site supervisors to undergo MEWP management training (such as the IPAF MEWPs for Managers course).

The Crucial Triad: Training vs Familiarisation vs Authorisation

Under British Standard BS 8460 and PUWER Regulations 8 and 9, candidate confusion often arises regarding the distinction between generic training, machine familiarisation, and site authorisation:

    ┌────────────────────────────────────────────────────────┐
    │ Step 1: Formal Category Training (PUWER Reg 9)         │
    │ - IPAF Operator Course (e.g. 3a Mobile Vertical, 3b)   │
    │ - Core operating principles, stability, PAL Card       │
    └───────────────────────────┬────────────────────────────┘
                                │
                                ▼
    ┌────────────────────────────────────────────────────────┐
    │ Step 2: Machine-Specific Familiarisation (PUWER Reg 8)  │
    │ - Exact make/model controls, auxiliary descent layout  │
    │ - Manufacturer handbook review, unique machine quirks  │
    └───────────────────────────┬────────────────────────────┘
                                │
                                ▼
    ┌────────────────────────────────────────────────────────┐
    │ Step 3: Employer Site Authorisation (HASAWA Sec 2)     │
    │ - Formal sign-off by site management to operate MEWP   │
    │ - Verification of RAMS, ground conditions, and card     │
    └────────────────────────────────────────────────────────┘

Conformity Marking and Machine Documentation

UKCA and CE Marking

Under the Supply of Machinery (Safety) Regulations 2008 (which implemented European Machinery Directive 2006/42/EC into UK law, modified for the UKCA framework post-Brexit), all MEWPs placed on the market in Great Britain must:

• Comply with the Essential Health and Safety Requirements (EHSRs), typically by conforming to the designated design standard BS EN 280-1:2022 (which replaced EN 280:2013+A1:2015).
• Affix a permanent UKCA (or recognised CE) mark to the machine data plate.
• Be accompanied by a manufacturer Declaration of Conformity (DoC), proving independent or self-certified compliance with design and safety testing standards.

The Manufacturer Operator Manual

PUWER Regulation 8 requires that operators have adequate health and safety information and written instructions. For a MEWP that means the manufacturer's operator's manual, and both manufacturers and the international operator-training standard (ISO 18878) require it to be kept in the weather-resistant storage compartment on the machine when it is not being read.

Operators must verify during their pre-use check that:

• The manual stored inside matches the exact make, model, and series of the MEWP;
• The manual is intact, legible, and complete;
• If the manual is missing, damaged, or unreadable, the machine must not be operated until an OEM replacement is sourced.
