Water Hygiene & Legionella Risk Assessment

Water Hygiene is essential to public and employee health, as well as the wider environment. That’s why it’s important to ensure your business is aware of the risks of legionella, as well as understands how to minimise those risks.

What is Legionella?

Legionella bacteria can survive and multiply in hot and cold water system pipework, cooling towers and evaporative condensers, calorifiers and cold water storage cisterns as well as spa pools.

The bacteria are dispersed in small water droplets known as aerosols, which are created whenever water impacts against a hard surface – such as those created by taps and showers.

If susceptible people breathe in these aerosols that contain the Legionella d bacteria, they may contract Legionnaires disease, or one of the other forms of Legionellosis that is caused by Legionella bacteria.

Regulation exists under the Health and Safety at Work etc Act 1974 (HSWA). There are also other frameworks such as the Management of Health and Safety at Work Regulations (MHSWR) and the Control of Substances Hazardous to Health Regulations 2002 (COSHH) that set out effective ways to assess and minimise the risks posed by Legionella bacteria.

Legionella Risk Assessment and Water Disinfection

Businesses themselves are responsible to ensure that they are complaint in controlling the risks of an outbreak of Legionella bacteria.
