GenVX Respirator Use
Donning
Before using your GenVX Series respirator, complete the assembly
instructions given on pages 19-20. Before putting on respirator, make sure
there is no dirt, dust, or contaminants inside the helmet.
1. Connect the Bullard air supply hose that is part of the NIOSH approved
assembly to the air source supplying Grade D breathing air. Turn on the
breathing air source.
2. With air flowing, connect breathing tube assembly to air supply hose.
Connect quick-disconnect fitting on breathing tube assembly to quick-
disconnect coupler on air supply hose. Once fitting is secured, release
coupling sleeve to lock fittings together. Pull on both hoses to make sure
they are attached securely.
3. Adjust air pressure at point-of-attachment (Figure 2, Page 13) to within
the approved pressure range on the Breathing Air Pressure Table (Pages
15-17) for approved pressure ranges.
4. With air still flowing, lower GenVX Series respirator helmet onto your
head for a comfortable fit.
5. Position headband for a comfortable fit. See instructions on pages 19 and
20 for proper headband sizing.
6. Pull elastic chin strap under your chin and adjust for a secure and
comfortable fit. The chin strap will help balance the helmet but is
not required.
7. Be sure that the knitted inner neck cuff fits snugly around your neck to
help provide a barrier to airborne contaminants.
8. With breathing tube assembly attached to the helmet, fasten belt around
waist or hips and adjust for comfort.
9. Pull respirator cape around your body and secure sides by connecting
the snap hooks. If using the Golden Gate cape, first secure the ties that
connect in back, then in front. If using the Hibernia parka, tighten belt
at waist.
10. Recheck air pressure and adjust if necessary.
11. With air still flowing into your respirator, you are now ready to enter
work area.
NOTE
OSHA respirator regulations do not require fit testing of
supplied air hoods and helmets.
Doffing
When finished working, leave work area wearing respirator and with air
still flowing. Once outside contaminated area, remove respirator and then
disconnect the air supply hose using the quick-disconnect fittings.
NOTE
If using V20 Series (1/2” I.D.) air supply hose, the quick-
disconnect coupler does not have a shut-off valve. Therefore,
air will continue to flow freely after disconnecting hose from
respirator.
WARNING
Do not put on or remove this respirator in a hazardous atmosphere
except for emergency escape purposes. Failure to follow this warning
could result in death or serious injury.
WARNING
Leave work area immediately if:
- Any respirator component becomes damaged.
- Airflow into respirator helmet stops or slows down.
- Air pressure gauge drops below the minimum
specified in the Breathing Air Pressure Table
(pages 15-17).
- Breathing becomes difficult.
- You become dizzy, nauseous, too hot, too cold or ill.
- You taste, smell or see contaminants inside
respirator helmet.
- Vision becomes impaired.
Failure to follow these instructions could result in death or serious injury.
WARNING
Do not leave respirator in work area. Respirable dust contaminants
can remain suspended in the air for more than one hour after
work activity ceases, even though you may not see them. Proper
work practice requires you to wear the respirator until you are
outside the contaminated area. Failure to don, doff and store the
respirator outside of contaminated area could result in exposure to
contaminants. Failure to follow these instructions could result in death
or serious injury.
