Consisting of two systems the PRA normally reduces the operating pressure to ___ psi before entering the regulators low pressure hose

The regulator then controls the pressure within the face piece to slightly ___ atmospheric pressure
Above
A malfunction of the PRA’s primary system will automatically direct breathing air into a secondary system. When this occurs, the operating pressure will only be reduced to ___ psi and the vibralert alarm to activate. Member must notify their officer and immediately leave the contaminated area accompanied to a safe area by another member using an SCBA.

Failure of both the primary and secondary systems in the open position will activate a relief valve in the PRA, which will rapidly discharge all pressure in excess of ___ psi into the atmosphere. When this occurs the cylinder valve should be ___ ___ allowing only a minimal amount of air to release, permitting the member to both breath and conserve air. The member must notify their officer and immediately leave the contaminated area accompanied to a safe area by another member using an SCBA

If the sensor module does not sense motion of the SCBA for ___ seconds, the Pak Alert SE 7 will signal a pre-alarm condition. If there is still no motion of the SCBA for the next ___ seconds, the full alarm will sound
20 seconds
12 seconds
The full alarm on the SCBA can only be cleared by?
Manually pressing the reset button twice, located on the side of the control console
If while using the SCBA, the batteries begin to approach the end of their useful life, the sensor module will begin to sound a chirp every ___ seconds and the green light on the control module will go out
2 seconds
SCBA’s must be inspected when (3)
- Immediately after the 0900 and 1800 hour roll calls
- Immediately before the start of MUD

If a cutting tool is to be used, it is best to keep it in the ___ pocket of the bunker coat
Right
If a leak from a damaged face-piece is more than can be controlled with one hand continue to cover as much of the damaged area as possible. Press the ___ ___ ___ after each breath to further limit the loss of breathing air. If the damaged area is too large to allow the regulator shut-off to release, then use the ___ ___ in an ON and OFF motion for each breath. This action helps to conserve the limited amount of breathing air necessary for escape.
Manual Shut-Off Switch
Purge Valve
