11.5 FIRE PROTECTION SYSTEMS
11.5.1 General
The Offshore Installations (Prevention of Fire and Explosion, and Emergency Response) Regulations (SI 1995/7434) require in Regulation 5 the Duty Holder to perform an assessment which shall consist (to quote from the regulations):
a) The identification of the various events which could give rise to:
(i)
a major accident involving fire or explosion; or
(ii)
the need (whether or not by reason of fire or explosion) for evacuation, escape or rescue to avoid or minimise a major accident.
b) The evaluation of the likelihood and consequences of such events.
c) The establishment of appropriate standards of performance to be attained by anything provided by measures for;
(i) ensuring effective evacuation, escape, recovery and rescue to avoid or minimise a major accident, and
(ii) otherwise protecting persons from a major fire or explosion; and d) The selection of appropriate measures.
With regard to helicopter emergencies, Regulation 7 requires the Duty Holder to ensure that equipment necessary for use in the event of an accident involving a helicopter is kept available near the helicopter landing area. The equipment provided will also need to comply with Regulation 19(1).
11.5.2 Main References
In addition to the PFEER requirements, detailed firefighting requirements for a helicopter landing area are also contained in CAP 437 and are based on international aviation standards and recommended practices contained in ICAO and IMO requirements.

11.5.3 Firefighting Safety Goals and Objectives
The goals of a helideck firefighting / hazard control system are to achieve the following:
1.
The preservation of life and rescue of helicopter occupants in a fire or crash situation
2.
The containment and extinguishment of the fire within the crash area
3.
The minimisation of exposure of helideck crews to fire and crash effects
4.
The minimisation of minor incidents to prevent escalation.
The means to be provided to achieve these aims, as far as is reasonably practical, should include equipment and facilities to allow:
1.
Rapid control of running fires and pool fires in all helicopter operating wind conditions
2.
Rapid control and smoke suppression during internal helicopter fires
3.
Rapid control of other fires likely to be encountered, e.g. engines, avionics bays
