The employer develops a fire protection program followed through every phase of construction and demolition and provides the firefighting equipment this subpart specifies, without delay as fire hazards arise; access to firefighting equipment is kept open, the equipment is conspicuously located, periodically inspected and kept in operating condition, and defective equipment is replaced at once; where the project warrants, a trained and equipped fire brigade is provided. A water supply of enough volume, duration and pressure for the firefighting equipment is available once combustible materials start to build up, and planned underground mains are completed and made available as soon as practicable. Portable equipment: one extinguisher rated at least 2A per 3,000 square feet of protected building area (or major fraction), within 100 feet travel of any point; an open 55-gallon water drum plus two fire pails, or a 1/2-inch garden hose line of no more than 100 feet delivering at least 5 gallons per minute with a 30-foot horizontal stream, may substitute for a 2A extinguisher; at least one 2A extinguisher on each floor, with one next to a stairway in multistory buildings; extinguishers and drums protected from freezing; an extinguisher of at least 10B within 50 feet wherever flammable gas above 5 pounds, or flammable or combustible liquid above 5 gallons, is in use (vehicle fuel tanks excepted); no carbon tetrachloride or other toxic vaporizing-liquid extinguishers; extinguishers inspected periodically and maintained to NFPA 10A-1970 and carrying a listing or approval from a nationally recognised testing lab (Table F-1 is a selection guide). Up to 100 feet of 1 1/2-inch hose delivering at least 25 gallons per minute may replace an extinguisher rated no more than 2A where it reaches all points; the contractor supplies adapters where hose connections do not match local fire department equipment; charged hose lines are available during demolition involving combustible materials. Automatic sprinklers being installed follow construction closely and go into service as soon as the law allows after each story; existing sprinklers stay in service during demolition or alteration as long as reasonable, control valves are operated only by authorised persons and are checked daily at close of work. Required or existing standpipes are brought up as soon as allowed and kept ready as work progresses, with a conspicuously marked street-level Siamese connection and at least one hose outlet per floor. An alarm system (telephone, siren or similar) lets employees and the local fire department be alerted, with the alarm code and reporting instructions posted at phones and employee entrances. The exit stairways and fire walls the finished building needs are built first, fire doors with automatic closers are hung as soon as practicable, and fire cutoffs are kept during alterations or demolition until the work requires their removal.
