Paragraph 7.4.1.3 – Fire-restricting materials

  1 This paragraph is intended to apply to all enclosed spaces and open cargo and ro-ro decks, except as defined below.

  2 Spaces considered as being of no fire risk and open decks (except open cargo and ro-ro decks) need not comply with this requirement. In this context, spaces of no fire risk are those containing no ignition sources and only insignificant combustible materials (in addition to the combustible hull structure). Lights and bilge alarm devices may be accepted in these spaces if smoke detection is provided.

  3 Dedicated storage rooms for gas fire-extinguishing systems may also be considered as spaces of no fire risk.

  4 Insulation systems approved as a 30-min or 60-min fire-resisting division, as per paragraph 7.2.1 of the Code, need not be qualified as a fire-restricting material, provided that the insulation is non-combustible, as per the International Code for Application of Fire Test Procedures, 2010 (2010 FTP Code).

  5 The test qualifying fire-restricting materials does not specify how to test floors. The following methods may be applied:

  • .1 for areas where a sprinkler system is not provided, a design with the deck of fibre-reinforced polymers covered by a non-combustible board or insulation faced with an approved floor covering according to the 2010 FTP Code, parts 2 and 5, may be accepted; and

  • .2 for areas where a sprinkler system is provided, a floor design with a floor covering approved according to the 2010 FTP Code, parts 2 and 5, applied directly on the deck constructed of fibre-reinforced polymers, may be accepted.
