During Use
G1 Powered Air-Purifying Respirator (PAPR)
US
- The respirator does not operate according to the instructions or training.
- Airflow decreases or stops.
Return to a safe atmosphere immediately if discoloration, crazing, blistering, cracking, or other
deterioration of the facepiece lens material occurs.
This respiratory protective device does not supply oxygen. Use the device only in areas that have
sufficient ventilation.
Do NOT let the battery discharge fully.
Do NOT use the rechargeable (NiMH) battery for more than 4 hours. Doing so can result in signifi-
cantly decreased airflow and permanent damage to the battery.
Do NOT use the single-use (Li-SO
2
) battery for more than 8 hours. Doing so can result in signifi-
cantly decreased airflow.
If the battery compartment becomes hot to the touch, go out of the contaminated area immediately
and move the power switch to the "OFF" position. Obey the applicable decontamination proce-
dures, clean and disinfect the respirator, then examine it.
Failure to obey these warnings can result in serious injury or death.
If you go out of the contaminated area at any time, do an in-use airflow test and a negative pressure
seal test before you go back into the contaminated area.
If the respirator is using a single-use (Li-SO
2
) battery, do an in-use airflow test after 4 hours of use and
again 2 hours later, after 6 hours of use.
If the respirator is using a rechargeable (NiMH) battery, do an in-use airflow test after 2 hours of use
and again 1 hour later, after 3 hours of use.
