Inspections - MSA AirHawk II Manual De Instrucciones

INSPECTION
Inspect the entire air mask after it is cleaned and
disinfected. ANSI Standards Z88.2 and Z88.5, describe
three levels of inspection procedures which are to be
performed. Refer to these documents, or to an inspection
program prepared by a health professional in establishing
an inspection program. Detailed repair procedures are
located in the MMR User's Maintenance Instructions.
If the air mask does not meet any of the following
inspections, it must be removed from service. Do not
inspect the air mask before cleaning if there is danger of
contacting hazardous contaminants. Clean and disinfect
first, then inspect. Failure to follow this warning can
cause inhalation or skin absorption of the contaminant
and result in serious personal injury or death.
COMPONENT INSPECTION
(AFTER EACH USE AND MONTHLY)
1. Don the air mask following the instruction procedures.
These steps make up the Air Mask Functional Test.
2. If all steps are performed successfully, remove the air
mask and inspect it following the steps below.
3. Facepiece
a. Inspect the facepiece for rubber deterioration, dirt,
cracks, tears, holes, or tackiness.
b. Check the harness headstraps for breaks, loss of
elasticity, missing buckles or straps. Check the
straps for signs of wear.
c. Inspect the lens for cracks, scratches, and a tight
seal with the facepiece rubber.
d. The exhalation valve must be clean and operate
easily. The valve must move off the seat and return
when released.
e. Inspect the facepiece coupling for damage. Also
check to be sure the spider gasket, and valve disc
are present.
4. Cylinder and Remote Gauges
a. Be sure you can see both gauge needles and face
clearly through the lens. Also be sure the gauge
stem is not bent.
b. Inspect the gauge hose for any visible damage.
5. Audi-Larm Audible Alarm
a. Check that the alarm is undamaged and clean.
b. Ensure that the Audi-Larm Coupling nut is hand-
tight (no tools).
6. Quick-Fill and URC Coupling Inspection
Inspect the URC and Quick-Fill coupling for tightness of
the coupling halves and tightness of the coupling to the
air mask. Perform both inspections simultaneously.
a. Close the cylinder valve and relieve system
pressure. (See DISCONNECTING THE FIREHAWK
PUSH-TO-CONNECT REGULATOR or
DISCONNECTING THE SLIDE-TO-CONNECT
FIREHAWK REGULATOR for instructions).
INSPECTION
b. Use a fine-tip ink
marker and a ruler or
straight edge to
draw a line on the
male coupling. Make
sure the line extends
across the joint and
coupling hex flats
onto the Audi-Larm
or Quick Fill manifold
body.
c. Put the dust cover on the coupling.
d. Grasp the dust cover by hand and, using maximum
effort, attempt to loosen the coupling at the joint by
turning the dust cover counterclockwise. Do not
use tools.
e. If the line does not
line up across the
joint...
...or across the joint
where the coupling
attaches to the air
mask, remove the air
mask from service
until a replacement
coupling is installed.
If the line does line
up, the coupling is
sufficiently tight and
the air mask may be
returned to service.
7. Cylinder
Breathing apparatus cylinders should be recharged as
soon as possible after use. Cylinders should not be
stored partially charged for two reasons:
•
If used without recharge, the service life of the
apparatus is reduced.
•
The cylinder burst disc vents excess pressure if a
full cylinder is over exposed to fire or heat. If the
cylinder is not full, it may be damaged before the
burst disc vents.
It is also essential that the required inspections and tests
be performed on all air mask cylinders in accordance with
Department of Transportation (DOT) regulations. DOT
regulations require that composite cylinders be retired
from service after the fifteenth year. Please note this does
