Legionella Risk Assessment

What is a Legionella Risk Assessment?

Under the Health and Safety Executives Approved Code of Practice (AcoP) L8 guidance there is a requirement for all commercial water systems to have a Legionella Risk Assessment. As per the AcoP L8; This Approved Code of Practice applies to the control of legionella bacteria, in any undertaking involving a work activity managed by you or on your behalf. It applies to premises controlled in connection with a trade, business or other undertaking where water is used or stored; and where there is a means of creating and transmitting water droplets (aerosols) which may be inhaled, causing a reasonably foreseeable risk of exposure to legionella bacteria.

A suitable risk assessment will identify and asses the risk of being exposed to legionella bacteria from water systems on the premises. It will also provide a list of control measures that should be taken to minimise the risk of bacterial growth in these water systems. These control measures may take the form of remediations such as: removing deal legs; removing underused water tanks; or increasing hot water storage temperatures.

Control measures can also take the form on ongoing maintenance activities such as: flushing of low usage outlets; temperature monitoring; descaling of shower heads; inspecting water tanks and calorifiers. All these control measures will be given in order to reduce the risk of bacterial growth in the water systems. The actions taken following a risk assessment should be recorded in a site log book (and kept for 5 years) and the risk assessment should be reviewed regularly to minimise the risk of exposure.
