WARNING
THESE EMERGENCY OPERATION PROCE-
DURES ARE FOR EMERGENCY USE ONLY
AND ARE MEANT TO SUPPLEMENT, NOT
REPLACE, THE EMERGENCY PROCE-
DURES PRESCRIBED BY YOUR
RESPIRATORY PROTECTION PROGRAM. IF
THEIR USE IS REQUIRED, LEAVE THE CON-
TAMINATED AREA AT ONCE. USE OF
THESE EMERGENCY PROCEDURES WILL
INCREASE THE RATE OF CONSUMPTION
OF THE AIR SUPPLY AND MAY CAUSE THE
END OF SERVICE INDICATOR ALARMS TO
DIMINISH IN INTENSITY OR STOP COM-
PLETELY. FAILURE TO RECOGNIZE THE
RISKS OF THESE EMERGENCY PROCE-
DURES MAY RESULT IN SERIOUS INJURY
OR DEATH.
WARNING
EMERGENCY PROCEDURE #3 IS THE ONLY
TIME THE RESPIRATOR MAY BE OPER-
ATED WITH THE CYLINDER VALVE LESS
THAN FULLY OPENED. USE OF A RESPIRA-
TOR WITH THE CYLINDER VALVE LESS
THAN FULLY OPENED OTHER THAN FOR
EMERGENCY PURPOSES MAY RESULT IN
SERIOUS INJURY OR DEATH.
WARNING
THE AIRFLOW THROUGH THE RESPIRATOR
WHEN THE PURGE VALVE IS IN USE CAN
EXCEED 200 LITERS PER MINUTE. TO RE-
DUCE AIR CONSUMPTION, THE AIRFLOW
MAY BE REDUCED BY PARTIALLY CLOSING
THE PURGE VALVE. FAILURE TO CON-
SERVE THE BREATHING AIR SUPPLY MAY
RESULT IN SERIOUS INJURY OR DEATH.
EMERGENCY OPERATION
The respirator is automatic in function requiring only the opening of
the cylinder valve and the proper donning of the facepiece to place
into use and the closing of the cylinder valve at the end of use. In
the event of a malfunction or a suspected malfunction, implement the
appropriate emergency procedure listed below:
1. Should the VIBRALERT or HEADS-UP DISPLAY actuate during
use, even if the air supply has not been depleted to approximately
25% of full rated capacity, LEAVE THE CONTAMINATED AREA
AT ONCE.
NOTE
ACTUATION OF THE VIBRALERT BEFORE THE AIR SUPPLY IS DE-
PLETED TO APPROXIMATELY 25% OF FULL RATED CAPACITY, MAY
INDICATE A FAILURE OF THE PRIMARY REDUCER PATH IN THE
PRESSURE REDUCER. ACTIVATION OF THE END OF SERVICE IN-
DICATOR ALARM BEFORE THE REMOTE AIR SUPPLY GAUGE INDI-
CATORS APPROXIMATELY 25% OR LESS OF FULL CAPACITY COULD
INDICATE A MALFUNCTIONING REMOTE AIR SUPPLY GAUGE OR
FAILURE OF THE END OF SERVICE INDICATOR ALARM. LEAVE
THE AREA REQUIRING RESPIRATORY PROTECTION IMMEDIATELY
ON THE ACTUATION OF ANY ALARM.
2. Should the air supply be partially or completely cut off during use,
fully open the purge valve (red knob on regulator) by turning it
counterclockwise, (pointer on knob downward) and check to be
certain the cylinder valve is fully opened (turned fully counterclock-
wise). LEAVE THE CONTAMINATED AREA AT ONCE AFTER
OPENING THE PURGE VALVE.
3. Should the air supply begin to flow freely into the facepiece dur-
ing use, fully open the purge valve (red knob on regulator) by turn-
ing it counterclockwise (pointer on knob downward), partially close
the cylinder valve by pushing in and rotating clockwise to regu-
late the flow of air to satisfy the requirements of the user. Do not
close the cylinder valve completely. LEAVE THE CONTAMINATED
AREA AT ONCE AFTER PARTIALLY CLOSING CYLINDER VALVE.
4. In the unlikely event of the blockage of air flow or sudden and
complete loss of the system air supply such that there is total ir-
reversible loss of respiratory protection, LEAVE THE CONTAMI-
NATED AREA AT ONCE USING ALL PRECAUTION AND FOLLOW
EMERGENCY PROCEDURES PRESCRIBED BY USER ESTAB-
LISHED RESPIRATORY PROTECTION PROGRAM.
If the above procedures are implemented during use, REMOVE
THE RESPIRATOR IN A SAFE AREA, tag the respirator and hold
it for service and repair by Authorized Personnel.
