Legionella Risk Assessments (L8)
Since legionella bacteria are abundant in natural water sources it is possible for the bacteria to enter other water systems including hot and cold water services and cooling towers. With the right conditions, for example temperatures between 20°C and 45°C, a supply of nutrients (rust, sludge or scale) and/or areas where water can stagnate, these bacteria will thrive. Once present within a water system these bacteria can be dispersed by using outlets such as taps, showers and hoses.
It is a legal requirement to consider the risks from legionella, which may affect your staff, residents or members of the public. In order to comply with the ACOP L8 it is essential that a risk assessment is carried out to establish the site conditions and identify any potential risk and any potential sources of exposure.
Once the risk assessment has been carried out it is the responsibility of the Duty Holder to comply with the ACOP and minimise the risk from legionella bacteria. If a risk is identified, which cannot be prevented, a control scheme must be introduced in order to manage the risk. A ‘responsible person’ should be appointed to take responsibility for managing the control scheme. The responsible person must be competent and have sufficient knowledge of the water system to manage the scheme effectively.
Thames Laboratories are able to undertake comprehensive assessments and provide reports that will include:
- An assessment of the usage of the water system and the type of people likely to be exposed to any potential risk from the water system being reviewed.
- A detailed assessment of the condition of all of the components of the water system (including but not limited to: cold water tanks, any hot water storage, showers and sinks/hand basins).
- A detailed schematic diagram of the system.
- An assessment of the current management structure, identifying any changes required to ensure full compliance with L8.
- Photographs to highlight any problem areas within the water system.
- Specific information highlighting any remedial work required to bring the system in line with current regulations.
- Microbiological samples can be taken if required, focusing on any potential high risk areas identified during the assessment.
