Division .8 F1

Machinery spaces of category A above 500 m ³ in volume shall, in addition to the fixed fire-extinguishing system required in this Regulation, be protected by an approved type of fixed water-based or equivalent local application fire-fighting system, based on the guidelines in IMO MSC/Circ.913 ‘Guidelines for the approval of fixed water-based local application fire-fighting systems for use in category A machinery spaces’.

In the cases of periodically unattended machinery spaces, the fire-fighting system shall have both automatic and manual release capabilities. In the case of continuously manned machinery spaces the fire-fighting system is only required to have a manual release capability.

Fixed local application fire-fighting systems are to protect areas such as the following without the necessity of engine shutdown, personnel evacuation or sealing of spaces:

1. .1

   F2the fire hazard portions of internal combustion machinery used for the ship's main propulsion and power generation, and for ships built on or after 1 January 2018 , the fire hazard portions of all internal combustion machinery,

2. .2

   boiler fronts,

3. .3

   the fire hazard portions of incinerators, and

4. .4

   purifiers for heated fuel oil.

Activation of any local application system shall give a visual and distinct audible alarm in the protected space and at continuously manned stations. The alarm shall indicate the specific system activated. The system alarm requirements described within this paragraph are in addition to and not a substitute for the detection and fire alarm systems required elsewhere in this chapter.
