Nova Scotia Offshore Petroleum Installations Regulations (SOR/95-191)

24. (1) Every manned installation shall be provided with a fire hydrant system in accordance with this section.

(2) The fire hydrant system shall be connected to a continuously pressurized wet pipe water main that

• (a) is connected to at least two pump systems that are situated as far apart as possible; and

• (b) when any one of the pump systems required by paragraph (a) is out of operation,

  • (i) is capable of delivering at least one jet simultaneously from each of any two fire hydrants through the hoses and nozzles, at a pressure at the hydrants of at least 350 kPa,

  • (ii) is capable of delivering water at a sufficient pressure and quantity so that the aggregate capacity of the pump systems that are still operating is not less than 120 m³/hour when the pump systems are delivering water to the fire hydrants, and

  • (iii) is capable of maintaining a pressure of at least 700 kPa to any foam system protecting the helicopter deck.

(3) The number and position of the fire hydrants in the fire hydrant system shall be such that water from any two hydrants, one of which is fitted with only a single length of fire hose and the other of which is fitted with one or two lengths of fire hose, can reach every part of the installation where a fire may occur.

(4) Each fire hydrant in the fire hydrant system shall be provided with a hose that

• (a) is of not more than 18 m in length;

• (b) is equipped with a 19 mm dual purpose nozzle capable of spray or jet action and with the necessary couplings; and

• (c) meets the requirements of National Fire Protection Association 1961, Standard on Fire Hose.

25. (1) In this section,

“water deluge system”

“water deluge system” means a system capable of deluging a space with water from fixed heads; (système déluge)

“water monitor system”

“water monitor system” means a system capable of deluging a space with water from monitors. (système de régulation d’eau)

(2) Every manned production installation shall be equipped with a water deluge system or, in the case of an open space, a water monitor system, for each space in the installation that contains equipment that stores, conveys or processes petroleum not used as fuel on the installation.

(3) The systems required by subsection (2) shall be

• (a) connected to a continuously pressurized water main that is connected to at least two pump systems; and

• (b) capable of discharging water at the rate of at least 12.2 L/minute/m² over the largest area served by the system when any one of the pump systems is out of operation.

(4) Every water deluge system shall

• (a) operate automatically in response to a signal from the fire detection system;

• (b) be capable of being operated manually from the control station and from locations close to but outside of each space served by it; and

• (c) when in operation, automatically activate an audible and visual signal at the fire and gas indicator panel in the control station.

(5) Every water monitor system shall

• (a) be capable of being activated manually from the control station and from locations close to but outside of each space served by it;

• (b) have sufficient movement in the horizontal and vertical planes to permit the monitor to discharge water into any part of the space served by it;

• (c) be capable of being locked in any position; and

• (d) be capable of discharging water as a jet or spray.

(6) A water deluge system provided pursuant to subsection (2) shall meet the requirements of National Fire Protection Association 15, Standard for Water Spray Fixed Systems for Fire Protection.
