(a) is necessary to reduce the effect of vibration;
(b) has a length that is not more than six times the diameter of the rigid pipe to which it is attached;
(c) is clearly visible at all times;
(d) is oil-resistant;
(e) is certified by a product certification body or a testing laboratory as meeting
(f) can withstand collapsing due to suction; and
(g) is secured at each end with a corrosion-resistant and galvanically compatible fitting that consists of
(2) A metallic hose clamp may be used only with a flexible hose that is designed for clamps. The hose clamp must be
Fixed Gas Fire-extinguishing Systems
(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
(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
(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
(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
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
pre-engineered system means, in respect of a fixed fire-extinguishing system, a system that
340 (1) The piping, valves and fittings of a fixed fire-extinguishing system must be made of galvanized steel or another material of equivalent corrosion and fire-resistance, and must be securely connected to one another and securely supported.
(2) The components of the fixed fire-extinguishing system must be resistant to or protected from mechanical, chemical or other damage that could render them inoperative.
(3) The relief valves of the fixed fire-extinguishing system must be safely vented.
Controls and Alarms
(2) Means must be provided in the wheelhouse, or in a location readily accessible from the position where the means of control is located, to
(3) If the machinery space has a gross volume of more than 57 m3 or is normally occupied, the fixed fire-extinguishing system must not have an automatic means to release the extinguishing agent.
(4) Unless the machinery space is too small for a crew member to enter it, the fixed fire-extinguishing system must have an alarm to warn of any impending release of the extinguishing agent. The alarm must
(a) be separate from any other alarm;
(b) have a sound that is distinct from the sound of any other signal or alarm in the space;
(c) have a sound level of more than 85 dB;
(d) if the space has an ambient noise level that exceeds the sound level of the alarm, have flashing red lights or beacons of sufficient intensity and number to alert the occupants of the space; and
(e) be set off automatically when the system is activated, and stay on for at least 20 seconds, or any longer period that is necessary to allow the occupants of the space to escape, before the agent is released.
(5) If the fixed fire-extinguishing system has an automatic means to release the extinguishing agent,
