Test for a tight fit with the M50 gas mask as follows: With a hand over the front module assembly, blow out hard to force out any air around the edges of the mask. With the palm of your hands, cover both primary filter inlet ports and breathe in. The mask should collapse against your face and remain so while you hold your breath. If it does the mask is airtight. If the mask does not collapse, check for leaks. If the mask still does not collapse, notify your superior.
