55 Reference to ISGOTT

 Reference is made to the International Safety Guide for Oil Tankers and Terminals, as amended.

55.2 Liquid cargoes with fire hazards requiring additional measures

  • 1 A liquid cargo with a flashpoint of less than 60°C for which a regular foam fire-fighting system complying with regulation II-2/61 is not effective, is considered to be a cargo introducing additional fire hazards in the context of regulation B-2/55.2. The following additional measures are required:

    • .1 the foam should be of alcohol resistant type; and

    • .2 the capacity and application rates of the foam extinguishing system should comply with chapter 11 of the IBC Code, except that lower application rates may be accepted based on performance tests. For tankers fitted with inert gas systems, a quantity of foam concentrate sufficient for 20 min of foam generation may be accepted. For determining which cargoes require the use of alcohol resistant foam, MSC/Circ.553 may be used for guidance.

  • 2 Liquid cargoes with a flashpoint above 60°C other than oil products or liquid cargoes, subject to the requirements of the Bulk Chemical Code are considered to constitute a low fire risk, not requiring the protection of a foam extinguishing system.

  • 3 For the purpose of this regulation, a liquid cargo with a vapour pressure greater than 1.013 bar absolute at 37.8 °C is considered to be a cargo introducing additional fire hazards. Ships carrying such substances should comply with paragraph 15.14 of the International Bulk Chemical Code (IBC Code). When ships operate in restricted areas and at restricted times, the Administration concerned may agree to waive requirements for refrigeration systems in accordance with paragraph 15.14.3 of the IBC Code.
