A legionella risk assessment is an important safety management process that will help to protect you, your employees and others from harm. In the United Kingdom it is required by law and is specifically identified by the Health & Safety Executive in their Approved Code of Practice (ACOP) L8 "Legionnaires' disease. The control of legionella bacteria in water systems".
What is a Legionella Risk Assessment?
A legionella risk assessment survey, also referred to as a legionella hazard analysis involves a systematic examination of the potential risks presented by engineered water systems, and seeks to identify and assess the risks of exposure to legionella bacteria from work activities and water systems.
Although it is impossible to guarantee that pathogenic micro-organisms such as legionella bacteria will not exist in engineered water systems, through proactive management and control procedures it is possible to significantly reduce the factors that allow such bacteria to proliferate in man-made water systems.
A legionella risk assessment is an essential risk management process and comprises a detailed examination of the risks presented by man-made water systems, and seeks to identify and assess the risks associated with Legionnaires' disease through exposure to legionella bacteria.
Identification & Assessment of the Legionellosis Risk
The UK's Health & Safety Executive (HSE) in their Approved Code of Practice (ACOP) L8, "Legionnaires' disease. The control of legionella bacteria in water systems" state that:
"A suitable and sufficient [risk] assessment must be carried out to identify and assess the risk of exposure to legionella bacteria from work activities and water systems on the premises and any precautionary measures needed ..."
Paragraph 28. HSE ACOP L8.
