What is legionella and why is it dangerous?

Legionnaires’ disease is a potentially fatal form of pneumonia, known to kill around 12% of those who become infected, particularly individuals with reduced immunity to infection. Transmitted by an airborne mist and can develop in still water between 20c and 45c, according to the HSE, legionella can affect any building or asset that has access to water.

What do the legionella regulations say?

Control of Substances Hazardous to Health Regulations 2002 (COSHH) provides a framework of actions designed to assess, prevent or control the risk from bacteria like Legionella and take suitable precautions. The duties under the health and safety at Work etc Act 1974 extend to the risks of legionella bacteria which may arise from work activities.

According to the HSE, a competent person should regularly check and clean all water systems in accordance with a legionella risk assessment.

Legionella Risk Assessments

A legionella risk assessment is crucial to achieving compliance for all duty holders, building or assets owners/managers, landlords and employers. Ensuring adequate measures are in place to prevent exposure to the bacteria is crucial in safeguarding individuals.

We work in close partnership with Healthy Buildings International (HBI) who have provided nationwide consultancy services for over 25 years. With HBI, we deliver a fully comprehensive legionella control service that puts you in control of your compliance requirements.
