Statutory compliance
Legionella and water hygiene
HSE's Approved Code of Practice L8 and guidance HSG274 require the duty holder to assess and control legionella risk in water systems. That means a written risk assessment reviewed regularly, a control scheme with monthly temperature checks at sentinel outlets, flushing of little-used outlets, and records kept for at least five years.
The law behind it
- Health and Safety at Work etc. Act 1974
