Legionnaires’ disease
The need for a risk assessment
All systems require a risk assessment, however not all systems will require elaborate control measures. A simple risk assessment may show that the risks are low and being properly managed to comply with the law. In such cases, you may not need to take further action, but it is important to review your assessment regularly in case of any changes in your system, and specifically if there is reason to suspect it is no longer valid.
The Law
Various laws govern the requirement for a landlord or agent to complete a risk assessment namely:
- Health and Safety at Work etc. Act 1974
- Control of Substances Hazardous to Health Regulations 2002 (COSHH regulations)
- Approved Code of Practice L8 (Fourth Edition) – Legionnaires’ disease. The control of legionella bacteria in water systems (ACOP)
- Technical Guidance HSG274 – Part 2: The control of legionella bacteria in hot and cold water systems
Heath and Safety at Work etc. Act 1974
Control of Substances Hazardous to Health Regulations 2002 (COSHH)
Regulation 6 of the COSHH provides both employers and self-employed persons (agents and landlords in this context) shall not carry out work which is liable to expose any person to any substance hazardous to health unless a suitable and sufficient assessment of the risk has been made.
Approved Code of Practice and Technical Guidance – L8
The ACOP and accompanying technical guidance makes it clear that legionella is a hazardous substance for the purpose of the COSHH regulations and provides the guidance which will assist with the making of a suitable and sufficient assessment of the risk (risk assessment for short).
This Guidance
Here we provide some practical guidance and a form for the production of a Legionella risk assessment. The guidance and form is suitable for a low risk domestic property where there is either a combination boiler or basic water storage for hot water which is being used daily.
