3228. (i) [FN1] Boiler, Furnace and Incinerator
					 Rooms.
Any room containing a boiler, furnace, incinerator, or
					 other fuel-fired equipment must be provided with two means of egress when both
					 of the following conditions exist:
(1) The area of the room exceeds 500 square feet, or
(2) The largest single piece of fuel-fired equipment
					 exceeds 1,000,000 B.t.u. per hour input capacity.
Exception: Rooms housing high-pressure boilers (greater
					 than 15 lbs. psi) where either of the conditions listed in (1) or (2) exist
					 shall be provided with 2 exits.
If two means of egress must be provided, one may be a fixed
					 ladder. The means of egress must be separated by a horizontal distance not less
					 than half the greatest horizontal dimension of the room. All openings shall be
					 protected with a self-closing fire assembly having a minimum one-hour
					 fire-protection rating. Where oil-fired boilers are used, a 6-inch
					 noncombustible sill (dike) shall be provided. There shall be no interior
					 openings between any occupancy where flammable or explosive concentrations may
					 be expected to accumulate.

(a) Where pipe valves require daily manipulation and are so
					 located that they cannot be reached or operated from the floor, a permanent
					 platform or other safe means of operation shall be provided.

					 shall be trained in the safe lighting and relighting of the equipment. It shall
					 be the responsibility of the employer to limit lighting and relighting of the
					 equipment to employees so designated. It shall be the responsibility of the
					 employees to follow the instructions given them. Copies of the instructions
					 shall be prominently displayed at a location near the equipment.
(b) In addition to the above fire boxes or combustion
					 chambers shall be purged or allowed sufficient time to vent themselves before a
					 source of ignition is introduced into them.
(c) Provision shall be made, for the furnishing of
					 extension lighting rods, where their use is indicated. Valves and other
					 controls shall be so located as to avoid placing the employee in an unsafe

3312. [FN4] Entering Combustion Chambers, Flues, Boilers or
					 Unfired Steam Pressure Vessels.
(a) Before employees are allowed to enter, through a
					 manhole, the shell or drum of a steam boiler or an unfired steam pressure
					 vessel for maintenance or repair, where such a boiler or pressure vessel is one
					 of a battery of two or more boilers or vessels or is connected to another
					 source of steam, the valves connecting to the steam header or other source of
					 steam shall be closed and effectively blinded or two valves shall be installed
					 with a bleeder between them and the valves shall be closed and bleeder open.
					 Blow down valves and other valves on lines through which harmful material might
					 accidentally flow back to the boiler or vessel shall be either sealed or closed
					 and locked and the key retained by the employee or his supervisor while the
					 employee is in the boiler or vessel. When lines are effectively blinded the
					 valves need not be locked or sealed.
(b) Employees shall not enter or be required to enter the
					 fire boxes, flues or combustion chambers of fired apparatus until:
(1) The pilot light, fuel and steam lines to burners
					 entering the fire box or combustion chamber have been blinded, disconnected or
					 effectively closed by the use of two block valves with an open bleeder between
					 them.
(2) All probability of ignition of any solid combustibles
					 in the fire box or combustion chamber has been removed.
