Legionnaires disease occurs as a result of infections caused by the legionellaceae family of bacteria. It is a form of pneumonia which results in around 250 identified cases a year and can prove fatal, especially to the elderly, young or those prone to respirable problems.

Legionnaires disease is contracted by inhaling small droplets of water suspended in air which contain the legionella bacterium. Legionnella bacteria occurs naturally in surface water but can also proliferate within man made environments such as cooling towers, domestic hot and cold distribution systems, water plant, humidifiers and air washers.

Proliferation of the bacteria typically occurs between 20oC - 45oC and is assisted by the presence of suitable nutrients present in dirt, sludge and scale as well as conditions of poor water flow, stagnation or where dead legs occur in water systems.


Employers are required to control the risk of exposure to legionella bacteria in accordance with Control of Substances Hazardous to Health Regulations (COSHH 2002). This is achieved by following the Approved Code of Practice (ACoP) L8. Learn more about how our legionella consultants can help you with the first step in this process, the risk assesments and your obligation to implement a legionella management scheme.
