REGULATOR CHECK
NOTE
THIS REGULATOR CHECK IS NOT INTENDED TO BE A COMPLETE
FUNCTIONAL CHECK OF THE RESPIRATOR.
BEFORE NEXT USE,
PERFORM A REGULAR OPERATIONAL INSPECTION AS DE-
SCRIBED IN THESE INSTRUCTIONS.
1. Check to make sure the respirator cylinder is at least 1/4 full.
2. Verify that the donning/air saver switch is fully depressed.
3. Close the purge knob.
4. Reattach the regulator to the respirator, (if removed for cleaning).
5. Slowly open the cylinder valve at least one (1) full turn.
6. If air flow from the regulator is heard, close the cylinder valve,
repeat steps 1, 2 and 3. If air flow is still heard, close the cylinder
valve fully, tag unit for repair and remove from service.
7. Open the purge valve and observe the air flow from the regulator
spray bar. Droplets of water indicate the regulator is not dry. Dry
the regulator according to Step 7 of PROCEDURE FOR CLEAN-
ING THE MASK MOUNTED REGULATOR section and repeat the
REGULATOR CHECK.
WARNING
FOLLOW THE REGULAR OPERATIONAL
INSPECTION PROCEDURE EXACTLY. IF
THE RESPIRATOR DOES NOT OPERATE AS
DESCRIBED OR ANY OTHER OPERATIONAL
MALFUNCTION IS NOTED, DO NOT USE THE
RESPIRATOR. REMOVE IT FROM SERVICE
AND TAG FOR REPAIR BY AUTHORIZED
PERSONNEL. FAILURE TO PROPERLY
INSPECT THE RESPIRATOR MAY RESULT
IN SERIOUS INJURY OR DEATH.
WARNING
PLACING RESPIRATORS IN STORAGE
WITHOUT THOROUGHLY DRYING THEM MAY
RESULT IN CORROSION OR OTHER DAMAGE
WHICH COULD CAUSE A MALFUNCTION OF
THE RESPIRATOR. SUCH A MALFUNCTION
MAY RESULT IN SERIOUS INJURY OR
DEATH.
WARNING
PLACING RESPIRATORS IN STORAGE
WITHOUT THOROUGHLY DRYING THEM MAY
RESULT IN RESIDUAL MOISTURE WHICH
MAY FREEZE IN COLD TEMPERATURES
AND CAUSE A MALFUNCTION OF THE
RESPIRATOR. SUCH A MALFUNCTION MAY
RESULT IN SERIOUS INJURY OR DEATH.
1. Check to ensure gasket is present between facepiece and mask-
mounted regulator and is not damaged.
2. Connect the regulator to the facepiece. With the red purge valve
in the 12 o’clock position, align the two flats of the outlet port with
corresponding flats in the facepiece port and insert. Rotate the
regulator counterclockwise (viewed from inside of facepiece) so
that the red purge valve knob is situated on the left side of the
facepiece. The lock tab on the mask-mounted regulator will lock
into the facepiece retainer with a “click.” If properly engaged, the
regulator will not rotate.
3. To reattach a breathing regulator equipped with a quick disconnect
to the respirator, see FIGURE 7.
4. Verify that the respirator is thoroughly dry before placing in
storage.
5. Place the clean and dry facepiece in a sealable enclosure to
protect until next use. Store in a manner that will not distort
the face seals.
6. Place the respirator in the carrying case, protective container, or
in a suitable storage location.
7. If any damage or deterioration is noted, remove the respirator
from service and tag for repair.
8. Where an SCBA, its spare components or related equipment are
stored or carried within a vehicle, such items shall be secured
by either a positive mechanical means designed to hold the item
in its stowed position, in a compartment with a positive latching
door, or in a closed container suitable to transport and contain
the SCBA and/or its spare components and associated equipment.
The mechanical means of holding the SCBA, its spare compo-
nents and associated equipment in place, the compartment or the
closed container shall be designed to contain the SCBA, its spare
components and associated equipment and thereby minimize the
possibility of injury to persons in or near the vehicle during move-
ment of the vehicle, especially during rapid deceleration or rapid
acceleration of the vehicle, sharp turns or an accident.
STORAGE OF THE RESPIRATOR
CAUTION
OVERTIGHTENING THE CYLINDER VALVE
MAY CAUSE DAMAGE THAT COULD RESULT
IN LEAKAGE OF AIR FROM THE CYLINDER.
USE NO TOOLS TO CLOSE THE CYLINDER
VALVE.
