HSG 274 Monitoring & Written Control Schemes

The HSE Approved Code of Practice  L8 (2013) states that:

“Once the risk has been identified and assessed, a written scheme should be prepared for preventing or controlling it.  In particular, the written scheme should contain the information about the water system needed to control the risk from exposure.”

The primary objective of the written scheme should be to avoid conditions that allow legionella bacteria to proliferate and to avoid creating a spray or aerosol.

For precautions to remain effective, the condition and performance of the system will need to be monitored. This will include:

  • Checking the performance and operation of the system and its component parts
  • Inspecting the accessible parts of the system for damage and signs of contamination
  • Monitoring to ensure that the treatment regime (be it chemical treatment or temperature control) continues to control to the required standard.

HBI can assist to develop a monitoring programme and written scheme of control that will facilitate your ongoing compliance with the Approved Code of Practice L8 (2013) and guidance documents HSG 274.
