General: Provide equipment capable of producing air of quality and volume required as applied to the Project conditions and crew size.

Air Quality: Provide air used for breathing in Type "C" supplied air respiratory systems that meets or exceeds standards set for C.G.A. type 1 (Gaseous Air) Grade D.

Face piece and Hose: Provide full Face piece and hose by same manufacturer, certified by NIOSH/MSHA as an approved Type "C" respirator assembly operating in pressure demand mode with a positive pressure Face piece.

Auxiliary Backup System: In atmospheres, which contain sufficient oxygen (greater than or equal to 19.5% oxygen), provide a pressure-demand full Face piece supplied air respirator equipped with an emergency backup HEPA filter.

Escape Air Supply: In atmospheres, which are oxygen deficient (less than 19.5% oxygen), provide a pressure-demand full Face piece supplied air respirator incorporating an auxiliary self-contained breathing apparatus (SCBA), which automatically maintains an uninterrupted air, supply in pressure demand mode with a positive pressure Face piece.

Backup Air Supply: Provide a reservoir of compressed air located outside the Work Area which will automatically maintain a continuous uninterruptible source of air automatically available to each connected Face piece and hose assembly in the event of compressor shut-down, contamination of air delivered by compressor, power loss or other failure.

Provide sufficient capacity in the backup air supply to allow a minimum escape time of one-half hour times the number of connections available to the Work Area. Air requirement at each connection is the air requirement of the respirators in use plus the air requirement of an average sized adult male engaged in moderately strenuous activity.

Warning Device: Provide a warning device that will operate independently of the building's power supply. Locate so that alarm is clearly audible throughout the Work Area and at the compressor with a volume above the noise level produced by equipment and work procedures in use. Connect alarm to warn of:

Compressor shut-down or other fault requiring use of backup air supply, Carbon Monoxide (CO) levels in excess of 10 PPM/V.

Carbon Monoxide (CO) Monitor: Continuously monitor and record on a strip chart recorder Carbon Monoxide (CO) levels. Place monitors in the airline between compressor and backup air supply and between backup air supply and workers. Connect monitors so that they also sound an alarm as indicated under "Warning Devices".

Compressor Shut-Down: Interconnect monitors, alarms and compressor so that compressor is automatically shut down and the alarms sounded if any of the following occur:

Carbon Monoxide (CO) concentrations exceed 10 PPM/V in the airline between the filter bank and backup air supply.

Compressor temperature exceeds normal operating range.

Compressor Motor: Provide a compressor driven by an electric motor. Ensure that electrical supply available is adequate to energize motor.

If building power supply is inadequate or as other factors may necessitate, provide gasoline or diesel compressor motor as follows.

Compressor Location: Locate compressor outside of building in location that will not impede access to the building, and that will not cause a nuisance by virtue of noise or fumes to occupied portions of the building.

Air Intake: Locate air intake remotely from source or automobile exhaust or exhaust from motors, or buildings.

After Cooler: Provide an after cooler at entry to filter system, which is capable of reducing temperatures to outside ambient air temperatures.

SELF-CONTAINED BREATHING APPARATUS (SCBA)

Configure system to permit the recharging of ½ hour 6220-PSI SCBA cylinders.
