Performance Steps

WARNING: Do not attempt to remove the hose from the facepiece on the M42 protective mask . This may cause leakage of toxic agents into the facepiece

CAUTION: Do not dunk the mask or the carrier in water. Wash the mask carefully so the canister and the microphone do not get wet. Keep water away from the inlet valve connections

CAUTION: Ensure that all components are entirely dry before reassembling the mask and storing it.

Note.  Each soldier, under the supervision of a qualified 54B (chemical operations specialist) or another trained person, must care for and maintain his protective mask.

Evaluation Preparation: 

Setup:  A good time to evaluate this task is during normal care and cleaning of the mask.  Place the required equipment on a field table or another suitable surface.  Simulate defects in the mask by removing components from the mask or using a defective mask not issued to the soldier.  During training and evaluation sessions, use an old set of filters or canister several times to avoid expending new ones each time.  If the soldier has not made adequate progress completing the task within 30 minutes, stop him and give him a NO GO.  This time standard is administrative.

Brief Soldier: Tell the soldier there is no time standard for this task on the job; but for testing purposes he must perform the task within 30 minutes.  Tell him to perform operator PMCS on the mask, to clean and condition his assigned protective mask, and to replace the filters in the mask. Tell the soldier that completing a DA Form 2404 is not part of the task.
