F.4 General (iv) The cabinet swing door shall be made openable such that it will not obstruct the retrieving of the fire hose by the fire fighter. (v) The depth of the cabinet shall not exceed 250mm for one fire hose or 350mm for two fire hoses. (vi) The cabinet shall be painted in a contrasting colour such that it is conspicuous and easily identified. (vii) The words, "FIRE HOSE", with letter height of at least 50mm and shown in contrasting colour, shall be painted directly on the front panel. (viii) In lieu of the cabinet, a simple wall mounted cradle for the fire hose can be provided, but only in the riser main shaft. The cradle shall be constructed and positioned to facilitate the retrieving of fire hose by the fire fighter. (ix) The cradle (in lieu of the cabinet) shall be maintenance free. The fire hose installation height shall be 400mm to 1500mm above finished floor level. (i) Only clean, dry and compact rolled hose shall be placed in the cabinet. (ii) Two lengths of spare fire hoses shall be kept in stock and ready for replacement. (iii) BS 6391 stipulates the technical requirements for quality acceptance standards of the fire hose. In addition, the above requirements shall be applicable for acceptance of the standby fire hose. Spare hoses Standard for Fire Safety in Rapid Transit Systems F-2
G.1 General APPENDIX G TENABLE ENVIRONMENT The purpose of this appendix is to provide guidelines for the details of the tenable environment. G.2 Environmental Consideration Some factors that should be considered in maintaining a tenable environment for periods of short duration are defined as follows: (a) Heat effects Exposure to heat can lead to life threat three basic ways: (1) Hyperthermia (2) Body surface burns (3) Respiratory tract burns For use in the modeling of life threat due to heat exposure in fires, it is necessary to consider only two criteria - the threshold of burning of the skin and the exposure at which hyperthermia is sufficient to cause mental deterioration and thereby threaten survival. Note that thermal burns to the respiratory tract from inhalation of air containing less than 10 percent by volume of water vapor do not occur in the absence of burns to the skin or the face; thus, tenability limits with regard to skin burns normally are lower than for burns to the respiratory tract. However, thermal burns to the respiratory tract can occur upon inhalation of air above 60°C that is saturated with water vapor. The tenability limit for exposure of skin to radiant heat is approximately 2.5 kW/m 2 . Below this incident heat flux level, exposure can be tolerated for 30 minutes or longer without significantly affecting the time available for escape. Above this threshold value, the time to burning of skin due to radiant heat decreases rapidly according to equation (1). where: t = time in minutes q = radiant heat flux in kW/m 2 tIrad = 4q -1.35 (1) Heat effects Standard for Fire Safety in Rapid Transit Systems G-1
