Chapter 7:

Fire safety


CHAPTER SUMMARY
Chapter 7 includes measures to ensure that fire safety systems and appliances are effective and operable, and that means of escape remain available under expected environmental conditions and at low air temperatures. These are clearly set out in the Chapter 7 wording below.

As adopted from IMO - Full Polar Code text

7.1 Goal
The goal of this chapter is to ensure that fire safety systems and appliances are effective and operable, and that means of escape remain available so that persons on board can safely and swiftly escape to the lifeboat and liferaft embarkation deck under the expected environmental conditions.

7.2 Functional requirements
7.2.1 In order to achieve the goal set out in paragraph 7.1 above, the following functional requirements are embodied in the regulations of this chapter:
  • .1 all components of fire safety systems and appliances if installed in exposed positions shall be protected from ice accretion and snow accumulation;
  • .2 local equipment and machinery controls shall be arranged so as to avoid freezing, snow accumulation and ice accretion and their location to remain accessible at all time;
  • .3 the design of fire safety systems and appliances shall take into consideration the need for persons to wear bulky and cumbersome cold weather gear, where appropriate;
  • .4 means shall be provided to remove or prevent ice and snow accretion from accesses; and
  • .5 extinguishing media shall be suitable for intended operation.
7.2.2 In addition, for ships intended to operate in low air temperature, the following apply:
  • .1 all components of fire safety systems and appliances shall be designed to ensure availability and effectiveness under the polar service temperature; and
  • .2 materials used in exposed fire safety systems shall be suitable for operation at the polar service temperature.
7.3 Regulations
7.3.1 In order to comply with the requirement of paragraph 7.2.1.1, the following apply:
  • .1 isolating and pressure/vacuum valves in exposed locations are to be protected from ice accretion and remain accessible at all time; and
  • .2 all two-way portable radio communication equipment shall be operable at the polar service temperature.
7.3.2 In order to comply with the requirement of paragraph 7.2.1.2, the following apply:
  • .1 fire pumps including emergency fire pumps, water mist and water spray pumps shall be located in compartments maintained above freezing;
  • .2 the fire main is to be arranged so that exposed sections can be isolated and means of draining of exposed sections shall be provided. Fire hoses and nozzles need not be connected to the fire main at all times, and may be stored in protected locations near the hydrants;
  • .3 firefighter's outfits shall be stored in warm locations on the ship; and
  • .4 where fixed water-based firefighting systems are located in a space separate from the main fire pumps and use their own independent sea suction, this sea suction is to be also capable of being cleared of ice accumulation.
7.3.3 In addition, for ships intended to operate in low air temperature, the following apply:
  • .1 In order to comply with the requirement of paragraph 7.2.2.1, portable and semi-portable extinguishers shall be located in positions protected from freezing temperatures, as far as practical. Locations subject to freezing are to be provided with extinguishers capable of operation under the polar service temperature.
  • .2 In order to comply with the functional requirements of paragraph 7.2.2.2 above, materials of exposed fire safety systems shall be approved by the Administration, or a recognized organization accepted by it, taking into account standards acceptable to the Organization or other standards offering an equivalent level of safety based on the polar service temperature.
