BOILERS AND UNFIRED PRESSURE VESSELS Fig. 16-5b. Men entering any confined space in boiler area (firebox, coal bunker, or ash pit for example) should wear a lifeline and be constantly watched by man sta tioned outside who is wearing similar protective equipment Explosion-proof 6 volt lamp is supplied by sealed step-down transformer in inspector's left hand damage Provision is often made so that a wall or large glass area will give away m case of an explosion inside the room Lighting In addition to being well il luminated, the boiler room should have a source of emergency lighting Gauges and controls should be-especially well lit so they can be read easily Exits, too, should be well lit and identified Exits Each boiler room should have two or more exits, one at each end of the room If a boiler extends more than one story above ground level, the room should have an exit at the boiler runway or floor level for each story This exit should lead to a fire escape on the outside of the building If the boiler room is in a basement (or subbasement) exits should lead to outside stairways and runways, and should have landings leading to the exit doors Stairs, ladders, and runways Some State and local boiler codes require the installa tion of stairs, ladders, and runways around boilers which extend 10 ft or more above floor level Even if not required by law, such access is desirable so that personnel can operate and service the boiler safely and without having to step on hot steam or water lines or stand on valve stems or handles Stairs, ladders, and runways must have handrails and toeboards Runways should be fabricated of steel grating to provide a nonslip surface and at the same time per mit circulation of air Walkways should not be near water glasses or safety valve discharge areas where an operator might accidentally be scalded 16-13
