Decking Installation Risk Assessment Template

Typical hazards & measures

• Structural instability during build — Brace frames and posts as erected; fit temporary diagonal bracing to resist racking. Follow sequence plans and do not overload incomplete spans. Use correct fixings torqued to specification. Verify support centres before loading with material packs or allowing access.
• 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.
• Adverse weather and heat/cold — Monitor forecast; pause lifting/cutting in high winds and cover frames. Provide shade and hydration in heat; warm layers and breaks in cold. Keep surfaces dry for bonding/finishing. Store timber off ground under breathable covers to minimise warp and moisture shifts.
• Lighting and low light work — Provide task lighting to remove shadows at cut points and fixings; use 110 V festoons and headlamps where needed. Illuminate access, edges, and delivery points. Check glare on glazing. Pause high-risk tasks if lux levels fall below safe visibility; re-plan for daylight where practicable.
• Hand–arm vibration from tools — Choose low-vibration drivers and drills; keep bits sharp and use pilot holes and jigs to reduce trigger time. Rotate tasks, record exposure, and keep hands warm. Maintain tools to reduce chatter. Use antivibration gloves for comfort and stop if tingling or whiteness appears.
