Vessel Fire Safety Regulations — 339
339 (1) Subject to subsection (6), every machinery space must be served by (a) a fixed gas fire-extinguishing system; or (b) a fixed aerosol fire-extinguishing system. (2) The fixed fire-extinguishing system must (a) be an engineered system certified for marine use by a product certification body or be of a type approved by a recognized organization, and be installed and maintained by the manufacturer, or a person authorized by the manufacturer, in accordance with the certification or type approval; or (b) be a pre-engineered system certified for marine use by a product certification body or be of a type approved by a recognized organization, and be installed and maintained in accordance with its design limitations and the manufacturer’s instructions. (3) Subsection (2) does not apply in respect of the design of pressure containers for a fixed fire-extinguishing system. Every pressure container for a fixed fire-extinguishing system must bear a mark indicating that it (a) meets the applicable requirements for transport by road or ship that are set out in section 5.10 of the Transportation of Dangerous Goods Regulations ; (b) meets the applicable requirements for transport by road or ship that are set out in Title 49, subpart C of part 178 of the Code of Federal Regulations of the United States; or (c) meets the applicable requirements for transportable pressure equipment that are set out in Directive 2010/35/EU of the European Parliament and of the Council and has undergone a conformity assessment procedure in accordance with that Directive by a notified body designated by a member state of the European Union. (4) When a fixed fire-extinguishing system is activated, a complete charge must be released simultaneously. (5) On a wooden or composite vessel, (a) a fixed gas or aerosol fire-extinguishing system must have two independent complete charges of gas or aerosol. The quantity of gas or aerosol for each charge must meet the requirements of subsection 345 (2), 346 (2) or 347 (2), as the case may be, respecting the quantity of gas or aerosol for the system; and (b) a fixed aerosol fire-extinguishing system must be certified by a product certification body or be of a type approved by a recognized organization for deep-seated fires in Class A materials. (6) A machinery space is not required to be served by a fixed fire-extinguishing system if (a) in addition to the portable fire extinguishers required by subsection 309 (1), the space is provided with a portable gas fire extinguisher that (i) does not weigh more than 23 kg, and (ii) meets the requirements of subsections 345 (2) and (3) or subsections 346 (2) and (5), as the case may be; (b) the space is provided with a readily accessible port that permits the additional portable gas fire extinguisher to be discharged directly into the space without the need to open the primary access to the space, and that is (i) labelled to clearly indicate its firefighting purpose and how to use it, (ii) capable of accommodating the discharge nozzle of the extinguisher, and (iii) arranged so that the extinguisher may be discharged in accordance with the manufacturer’s instructions; and (c) the additional portable gas fire extinguisher is located outside the space and close to the port. (7) The following definitions apply in this section. engineered system means, in respect of a fixed fire-extinguishing system, a system that requires calculations and a design that are specific to the vessel in which it is fitted and whose purpose is to determine the flow rates, nozzle pressures, pipe size, area or volume protected by each nozzle, the quantity of extinguishing agent and the number and types of nozzles and their placement. ( système sur mesure ) pre-engineered system means, in respect of a fixed fire-extinguishing system, a system that (a) does not require calculations, or a design, that are specific to the vessel in which it is fitted; and (b) is specifically limited as to the type of space it can
