A disposable N95
mask (respirator) is a safety device that covers the nose and mouth and assistance guard the wearer from breathing in some hazardous substances.
Place both hands totally
over the mask and inhale sharply. Be careful not to bother the location of the
mask. The mask should pull into your face. If air leaks around your face or
eyes, regulate the nose piece and straps and repeat the positive pressure check.
