Irrigation Install & Maintenance Risk Assessment Template

Typical hazards & measures

• Unintended startup of pumps/valves — Apply lockout/tagout to mains, isolators, and controller outputs. Remove fuses, bypass auto schedules, and verify zero energy. Depressurise lines before work, tag controls with “men at work,” keep keys under single control, and confirm restoration is staged and announced.
• Confined spaces in tanks/chambers — Assess oxygen/toxic risks, ventilate and test the atmosphere. Use top-man, tripod and harness where needed. Control access, isolate inlets/outlets, and keep communications live. Work to a permit with rescue plan, trained team, and suitable retrieval and first-aid equipment ready.
• Underground services — Review current utility plans, scan with CAT/Genny and mark routes. Hand-dig trial holes to confirm depth/line. Set dig limits, use insulated tools near electric, and brief permit-to-dig. Stop on warning tape or anomalies, re-survey with a competent supervisor before work resumes.
• Lone working and welfare — Avoid lone high-risk tasks; where unavoidable, use check-in protocols and man-down alarms. Provide accessible welfare, drinking water, and first aid. Ensure signal coverage or radios, known location, and a clear escalation plan with agreed response times and contacts.
• Noise and hand-arm vibration — Select low-vibration tools, record trigger times, and rotate tasks. Wear hearing protection near trenchers/compactors. Maintain sharp blades and damping handles. Plan quieter methods (e.g., hand dig near services) and schedule rest breaks to reduce cumulative exposure.
