valve, inhale quickly.
c):If the air leaks from the bridge of the nose, the nose clip should be readjusted according
to step 4; if the air leaks from the edge of the mask, the headband should be adjusted
again; if a good fit cannot be obtained, steps 1-4 should be repeated. d):If there is no air leakage, you can enter the work area.
