The primary legislation governing Legionella risk assessments in the Great Britain is the Control of Legionella Bacteria in Water Systems. These laws came into force in 2001 and were replaced by the Control of Legionella, Acoustic Condition in Services in 2004, with amendments. Regulatory Requirements Under the CLAS laws, organizations are required to implement a written scheme for the control of Legionella in their cooling towers. This plan should include the following components: Relevant engineering and construction factors Location of incoming water supply lines to premises or relevant areas Presence of any temperature control systems or systems where temperature levels exceed 20 degrees Celsius Type and volume of distribution systems Perform regular physical checks of the water storage tanks and other fittings Flush or drain stagnated storage tanks to clean them before performing regular physical inspections. Any part with water heating if possible. Businesses must also appoint someone to implement and monitor the plan. This person is usually referred to as the 'responsible person'. The responsible person must have expertise and training to implement the plan safely and effectively. The organization must keep records of the plan, including system maps, pipe layouts, and water flow rates, water sampling results, and maintenance records. These documents must be made available to HSE inspectors when requested. Regulatory Extensions The APR 2006 extend the application of the CLAS regulations to accommodation providers. Under the APR, hotels, nursing homes, and other establishments must take reasonable steps to identify and prevent the occurrence of Legionella in water systems. This includes the appointment of a responsible person and the implementation of a comprehensive water quality check and water safety plan. Risk https://legionellatesting.co.uk/rotherham/ should include the following components: Identification of potential sources of Legionella in the cooling tower (e.g. cooling towers, air-conditioning units) Description of any Legionella mitigation strategies in place (e.g. water treatment, water heating, water quality checks) Evaluation of the efficiency of existing mitigation strategies Recommendations for further mitigation strategies to reduce the likelihood of Legionella spread Regular Risk Assessment The risk assessment must be conducted by someone with sufficient knowledge and qualifications, usually every two years. However, some premises may require more frequent water quality checks, such as sites that have high levels of engineering activity or rapid growth requirements. Mitigation Requirement Once the water quality check has identified high risk, a corresponding set of works will typically be conducted and this can often require various techniques to control and deal with mitigation to get down to recommended guidelines normally maintained Important Point of Conclusion Legionella water quality checks are a critical component of any water safety plan. By understanding the requirements and ongoing laws through the controls you can be sure that a risk assessment fully embraces the entire domain, a system will naturally manage these contaminants minimizing the potential for an outbreak.
