Written Scheme of Control for Legionella
A written scheme of control for the control of legionella is a comprehensive risk management document that clearly identifies those measures required to control the risks from exposure to Legionella bacteria, and how those measures are implemented and managed so that control over water systems is achieved and remains effective.
The written scheme of control forms an essential risk management document that should be developed as a practical tool to be used by all stakeholders involved in the legionella control process.
The written scheme is separate to the legionella risk assessment and is a legal requirement identified by the Health & Safety Executive in their Approved Code of Practice and guidance ACOP L8 “Legionnaires’ disease. The control of legionella bacteria in water systems”.
Preventing or controlling the risk from exposure to legionella bacteria
“Where the [risk] assessment shows that there is a reasonably foreseeable risk of exposure to legionella bacteria, the use of water systems, parts of water systems or systems of work that lead to exposure must be avoided so far as is reasonably practicable. Where this is not reasonably practicable, there should be a written scheme for controlling the risk from exposure that should be properly implemented and managed. The written scheme should specify measures to take to ensure that it remains effective.”
Paragraph 58. Health & Safety Executive Approved Code of Practice and guidance L8 “Legionnaires’ disease. The control of legionella bacteria in water systems”.
Without an effective written scheme of control no water system can be claimed to be under effective control.
