Legionella Risk Review Checklist
This Legionella Risk Review checklist helps organizations assess and maintain compliance with HSE ACoP L8. It guides reviewers through site management, responsible person assignments, scope of systems, changes in occupancy or use, and staff training. It covers asset records and schematics, outlet and fixed asset registers, and supplementary biocide dosing. Detailed inspections for cold-water storage tanks and hot water vessels include integrity, insulation, corrosion, scale, valve operation, and temperature readings. Monitoring records verify temperatures or biocide levels, flushing of low-use outlets, shower disinfection, pump alternation, and validity of the risk assessment and control scheme. The template concludes with an assessor summary and photographic evidence.
