5.5 Provision and Use of Work Equipment Regulations 1998 (PUWER) & Equipment Inspections

Provision and Use of Work Equipment Regulations 1998 (PUWER) & Equipment Inspections

Plant, machinery, power tools, and access equipment are central to construction operations, yet unmaintained or inappropriately used work equipment is a leading cause of severe site injuries, amputations, and fatalities. The Provision and Use of Work Equipment Regulations 1998 (PUWER) place broad, stringent legal duties on employers, site managers, and contractors to ensure that all work equipment provided on site is safe, suitable for its intended purpose, regularly inspected, and operated exclusively by competent personnel.

1. Scope and Core Requirements of PUWER 1998

PUWER applies to all "work equipment" provided for use in the workplace. The definition of work equipment is comprehensive, encompassing everything from simple hand tools (hammers, chisels), portable power tools (saws, drills), and access equipment (ladders, mobile towers) to heavy plant (excavators, dumpers, telehandlers) and workshop machinery.

2. Statutory Inspection Regimes under PUWER Regulation 6

To ensure work equipment remains safe, PUWER Regulation 6 establishes a three-tier inspection regime:

+-----------------------------------------------------------------------------------+
|                        PUWER THREE-TIER INSPECTION REGIME                         |
+-----------------------------------------------------------------------------------+
|  [ DAILY PRE-USE CHECK ]     • Visual walkaround, oil/fluid checks, controls,     |
|  (By Plant Operator)           safety devices, tires, brakes, and warning lights.  |
|                                                                                   |
|  [ PERIODIC INSPECTION ]    • Formal written technical inspection by competent    |
|  (Weekly / Monthly)           fitter; recorded in site Plant Inspection Register. |
|                                                                                   |
|  [ EXCEPTIONAL CHECK ]      • Triggered after major modifications, overturns,     |
|  (Post-Event / Incident)      accidents, or prolonged periods of site inactivity. |
+-----------------------------------------------------------------------------------+

1. Pre-Use Checks (Daily)

Conducted by the operator at the start of every shift using a structured checklist. Includes checking fluid levels, hydraulic hoses, tires/tracks, seatbelts, lights, steering, braking systems, and emergency stops. Any safety-critical defect must result in immediate tagging out and removal of keys.

2. Periodic Inspections (Weekly / Monthly)

Detailed, documented technical inspections carried out by a competent plant technician. Results must be recorded in the site Work Equipment Register and retained on site for statutory inspection by HSE inspectors.

3. Exceptional Inspections

Mandatory inspections conducted whenever equipment is subjected to exceptional circumstances liable to jeopardize safety—such as after an overturn, structural impact, major repair, or extended storage.

3. Machinery Guarding Hierarchy (Regulation 11)

PUWER Regulation 11 requires employers to take effective measures to prevent access to dangerous parts of machinery or stop the movement of dangerous parts before access is gained. Regulation 11 sets out a strict statutory Guarding Hierarchy:

1. Fixed Enclosing Guards (First Choice): Physical guards attached by permanent means (welded) or fasteners (bolts, screws) that require tools for removal. Example: Fixed metal casing covering a table saw drive belt.
2. Other Physical Guards (Interlocked): Guards that physically prevent machine operation unless the guard is closed and locked. Opening the guard automatically cuts power to the dangerous drive mechanism.
3. Protection Devices: Sensors, trip devices, light curtains, or pressure-sensitive mats that bring moving parts to a complete stop before a worker can reach the hazard zone.
4. Information, Instruction, Training & PPE (Last Resort): Relying on push-sticks, warning notices, safety glasses, and operator caution. This tier is permissible ONLY where physical guards are proven technically impracticable.

4. Mobile Work Equipment Safety (PUWER Part III)

Mobile plant (dumpers, excavators, rollers, telehandlers) accounts for a high proportion of severe site incidents. PUWER Regulations 25 to 30 impose specific safety controls for mobile plant:

ROPS and FOPS Structures (Regulation 25 & 26)

• Roll-Over Protective Structures (ROPS): Reinforced cab frames designed to preserve a survival space for the operator in the event of a plant overturn.
• Falling Object Protective Structures (FOPS): Reinforced cab roofs designed to protect operators from falling masonry or materials.

Seatbelt Enforcement & Site Rules

• "No Belt, No Operate": ROPS structures only protect operators if they remain inside the protective cab envelope during an overturn. Site managers must strictly enforce lap-belt compliance on forward tipping dumpers and excavators.

Visibility Aids & Pedestrian Segregation

• 360-Degree Visibility: Plant must be fitted with convex mirrors, 360-degree camera systems, and radar proximity sensors to eliminate blind spots around large excavators and dumpers.
• Audible Warning Devices: Automatic white-noise reverse alarms and flashing beacons are mandatory on all site vehicles.

5. Controls, Isolation, and Emergency Stops (Regulations 14–18)

• Control Systems: Operating controls must be clearly marked, accessible, and designed to prevent accidental actuation (e.g., shrouded start buttons or dead-man switches).
• Emergency Stop Buttons (Regulation 18): Emergency stops must be clearly visible, easily reachable, and feature a red mushroom-head button mounted on a yellow background. Actuating an emergency stop must bring dangerous moving parts to a complete stop immediately without creating secondary hazards.
