The Emergency Generator Room should be designed in accordance with NFPA 2001: "Clean Agent Fire Extinguishing Systems" and complies with Class Rules and SOLAS requirements.  The system will include a time delay prior to discharge with alarm and warning lights to allow personnel to evacuate the area prior to discharge.

High expansion foam system should be used instead of water mist for the Pump Room which will be designed in accordance with NFPA 11: "Low, Medium and High Expansion Foam Systems" and complies with Class Rules and SOLAS requirements.  The following design and operational elements should be incorporated:

  • Access to the pump room should be controlled
  • Activation should be manual and should only be achieved when no personnel have been confirmed to be in the Pump Room
  • Audible and visual warning of the release of the system should be provided.
  • Anyone entering the pump room following a release of foam should be required to wear a breathing apparatus to protect them from oxygen deficient air and products of combustion entrained in the foam blanket.
