2-8. Testing Air Flow Alarm

.
Always test air flow alarm
before using the respirator.
Also check air flow alarm
each month if respirator is
not used regularly.
Disconnect hose from hood. Start
blower and block air flow by placing
your hand over the end of the hose.
Continue blocking air flow until
alarm sounds and the blower vi-
brates (about 15 to 20 seconds).
If alarm does not sound and the
blower does not vibrate, check bat-
tery and filter element.
