A recap on what tests and monitoring you implement and reviewing your Water Risk Assessment at scheduled periods ensures you monitor your status and compliance before an accident, incident or harm to health occurs.

This entails confirming or otherwise that you have been successful with the plans and objectives that you have implemented, the operation of your health and safety management regime, and subsequent compliance with performance standards. e.g. for hot water outlets the water temperature should be at least 50 °C within a minute of running the water.

The following questions will enable you to decide if your approach Legionella control is effective or if it needs revisions.

  1. Do you have a written Water Risk Assessment for your systems?
  2. Does the Water Risk Assessment include a description of your system, e.g. an up-to-date schematic diagram of the system?
  3. Does the Water Risk Assessment confirm that there is currently no significant risk?
  4. If the Water Risk Assessment has identified a significant risk then:
    * Is there a written control scheme in place to address the risks?
    * Has a ‘responsible person’ been nominated in writing?
    * Have the roles and responsibilities of all staff involved in the control plan been clearly defined in writing and have each of them received appropriate training?
  5. Where external contractors are used, have their roles and responsibilities clearly defined, in writing, and have subsequent checks on the competence of the contractors/consultants and found it acceptable (e.g. experience and qualifications, training, membership of professional organisations or recognised trade body)?
  6. Have all other health and safety issues been considered  (e.g. COSHH assessments for handling of water treatment chemicals, working at height, working in confined spaces, electrical safety and ease of access to parts of the system)?
