Flashcards in SCBA/Fast-Pak/Pak-Tracker Deck (36)
Because the facepiece does not cover the ears, airborne contaminants can enter the respiratory tract through a ___ or ___ eardrum
Punctured or ruptured
A confined space is defined as any area that is not designed for ___ human occupancy. Large enough so a person can ___ and ___. Has limited means for ___ and ___
Enter and Work
Entry and Escape
The SCBA cylinder holds ___ breathing air
The service life of a cylinder is ___ years
Hydrostatic testing is done every ___ years. 10 minute escape cylinders used by SOC units for confined space need to be hydrostatic tested every ___ years
Inspect all spare cylinders (depots, high-rise units, company and reserve apparatus) weekly on ___ for FULL pressure
Designated training cylinders are designated with a ___ top and/or a ___ protective sleeve
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
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 manual shut-off fails to release for any reason, turn the red purge valve ___, ___ degrees to start the flow of air
If failure of the regulator in the open position (too much air flow in the face-piece), air-flow can be controlled by opening the purge valve ___ and ___ closing the cylinder valve.
The vibralert and HUD work ___ and may not activate at precisely the same time.
Will the vibralert alarm for malfunction of the PRA's primary system?
The spray bar on the regulator is comprised of ___ small holes
When the cylinder valve is turned on the HUD will initialize and illuminate for ___ seconds
Two green indicator lights on the HUD mean
The cylinder is full
One green indicator light on the HUD means
One yellow indicator light flashing slowly (once a second) means
One red light flashing rapidly (10 times a second) means
1/4 cylinder (Leave the hazardous area)
When the batteries require changing, the round low battering indicator at the far right of the HUD will light for ___ seconds and begin to flash slowly at ___ a second
Once a second
Color of Face-pieces:
Units requiring a spare small or extra large face piece shall contact their?
When putting on the face piece in what order do you pull the straps?
First the bottom and then the top
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
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
SCBA's must be inspected when (3)
1. Immediately after the 0900 and 1800 hour roll calls
2. Immediately before the start of MUD
3. After each use
