Legionella Risk Assessment
Legionella pneumophila and related strains of Legionella Bacterium are waterborne pathogens commonly found in low numbers in natural watercourses.
Legionella may via the mains water supply, colonise man made hot and cold water systems, cooling towers & evaporative cooling systems as well as spa pools or jacuzzis.
If these systems are poorly maintained or managed and conditions are favourable the bacteria may grow within these systems leading to an increased risk of Legionellosis (the collective term referring to the pneumonia like diseases’ caused by the bacteria).
The first step to manage this risk is to assess the level of risk within your premises. The HSE’s publication Legionnaires’ Disease: The Control of Legionella Bacteria in Water Systems Approved Code of Practise and guidance (2013) states that:
“A suitable and sufficient 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”
The AcoP L8 (2013) also states that:
“The dutyholder must ensure that the person who carries out the risk assessment and provides advice on prevention and control of exposure must be competent to do so.”
The legionella risk assessment must be regularly reviewed to ensure it remains up-to-date, specifically if it is no longer valid. This may result from:
- Changes to the water system or its use
- Changes to the use of the building in which the water system is installed
- The availability of new information about risks or control measures
- The results of checks indicating that control measures are no longer effective
- Changes to key personnel
- A case of Legionnaires’ disease / legionellosis associated with the system.
At HBI we pride ourselves on the quality of our risk assessments -developed to ensure compliance with BS 8580: Water Quality. Risk assessments for Legionella control. Code of practice and are also UKAS accredited.
Most importantly however we provide you with an informative user friendly assessment of your buildings water systems highlighting areas of non-compliance and providing you with a prioritized list of actions where applicable to help you control and reduce risk within your building.
