Canada Oil and Gas Installations Regulations — 28
28 (1) On every offshore installation, a fixed fire- extinguishing system utilizing carbon dioxide, pressure water spray or, where a fire will not involve any gases, liquefied gases with a boiling point below ambient temperature or cryogenic liquids, high expansion foam shall be installed in every space containing (a) internal combustion machinery having an aggregate power of at least 750 kW; (b) an oil- or gas-fired boiler or any other fired process vessel having a thermal rating of at least 75 kW; (c) paint or other flammable liquids as defined by National Fire Protection Association 321, Standard on Basic Classification of Flammable and Combustible Liquids ; or (d) mud pits or equipment used for removing drill solids where oil-based mud is used. (2) On every offshore installation, a fixed fire-extinguishing system utilizing carbon dioxide or pressure water spray shall be provided in every compartment containing a pump for the transfer of oil. (3) A fire-extinguishing system utilizing carbon dioxide referred to in subsection (1) or (2) shall meet the requirements of National Fire Protection Association 12, Standard on Carbon Dioxide Extinguishing Systems . (4) A fire-extinguishing system utilizing pressure water spray referred to in subsection (1) or (2) shall meet the requirements of National Fire Protection Association 15, Standard for Water Spray Fixed Systems for Fire Protection . (5) A fire-extinguishing system utilizing high expansion foam referred to in subsection (1) shall meet the requirements of National Fire Protection Association 16, Standard on Deluge Foam-Water Sprinkler and Foam-Water Spray Systems . (6) When a fire-extinguishing system utilizing carbon dioxide is provided pursuant to subsection (1) or (2), means shall be provided to (a) stop all ventilation fans serving the space protected by that system automatically before the system is activated; and (b) close all dampers in the ventilation system serving the space protected by that system manually from a position that is outside that space and that will not be made inaccessible by a fire within that space. (7) Every fire-extinguishing system referred to in subsection (1) or (2) shall be capable of being activated manually (a) from a location close to but outside each space served by it; and (b) at the location where the extinguishing medium is stored. (8) At each access to every space served by a fire-extinguishing system referred to in subsection (1) or (2) there shall be a notice indicating that the space contains such a system and stating which fire-extinguishing medium is used. (9) Visual indication of the operational status of the fire-extinguishing system referred to in subsection (1) or (2) shall be provided at each access to every space served by that system and at the control station. (10) Every offshore installation provided with a fire-extinguishing system referred to in subsection (1) or (2) shall be provided with an automatic system that will give (a) an audible warning, in every space served by that system to which personnel have access, before the fire-extinguishing medium is released from the fire-extinguishing system; and (b) an audible and visual signal, outside the access to every space served by that system and at the fire and gas indicator panel in the control station, when the fire-extinguishing system is in operation. (11) Every offshore installation provided with a fire-extinguishing system referred to in subsection (1) or (2) shall be provided with means to close all openings that may admit air to or allow gas to escape from a space served by that system.
