Legionella Risk Assessment — Water Systems
The legionella risk assessment for the hot and cold water systems of premises a construction business controls — office, yard, welfare units and cabins, a vacant or part-occupied building under refurbishment, small let premises: the duty holder and the responsible person, screening questions that stop at cooling towers and other risk systems, the system and its schematic, the risk factors, a 5×5 rating before and after actions, a control scheme carrying every row of HSE's hot and cold water checklist with what to do when a check is out of limits, buildings out of use, sampling, records and retention, review triggers, and how the findings were shared.

Statutory basis, cited on the form
- COSHH 2002 regs 6 and 7

- MHSWR 1999 reg 3
- Notification of Cooling Towers and Evaporative Condensers Regulations 1992 regs 2 and 3
Guidance and standards relied on
These are not law. HSE guidance carries no statutory force in itself, British Standards and NASC technical guidance are industry documents, and the Joint Code of Practice is an insurers' code. They are what the document is built to — and where a court would look for the standard of the reasonable contractor.
What it is not
It is not a completed document and it is not health and safety advice. You must adapt it to your site and have a competent person complete and sign it off. See why we don't say "compliant".
Format
