Decking Installation Risk Assessment Template

Typical hazards & measures

• Use of electrical tools — Inspect cables, plugs, and casings before each use; use 110 V or battery tools with RCD protection. Keep leads off wet ground and away from sharp edges and trip zones. Store tools in dry shelters; remove damaged items from service; stop use if overheating, sparking, or faults are detected.
• Ladders and temporary access — Select industrial ladders at 1:4 pitch, secure at top or foot, and maintain three points of contact. Keep use short-duration. Step-ladders fully opened and locked. Store tools in belts, not hands. Ensure firm level ground, avoid side-loading and over-reaching, and inspect each shift.
• Treated timber preservatives — Confirm use-class suitability. Wear gloves and eye protection when cutting; avoid skin contact with residues. Do not burn off-cuts. Containerise waste and sawdust. Prevent run-off to drains. Use stainless or compatible fixings to avoid corrosion and staining on finished work.
• Noise exposure — Plan noisy tasks together; use well-maintained saws and blades. Establish hearing protection zones and provide suitable SNR-rated plugs or muffs with fit checks. Limit exposure with rotation and schedule high noise when fewer people are present. Monitor levels as needed.
• Excavations and ground instability — Assess soil and water table; batter sides or use post-hole liners. Keep spoil and fill set back; plate soft spots and fence open holes. Verify bearing with simple pen tests. Backfill and compact in layers. Cap or cover holes if left unattended and secure at close of play.
