RT Series Respirator Use
Donning the RT Respirator
Before using your RT Series respirator, assemble the respirator using the
instructions given on page 6.
1. Connect NIOSH approved Bullard air supply hose to an air source supplying
Grade D breathable air as defined on page 4. Turn on breathing air source.
2. With air flowing, connect breathing tube assembly to air supply hose (see
Figure 7). 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 to within the approved pressure
range (see Figure 8). See the Breathing Air Pressure Table (page 5) for ap-
proved pressure ranges.
4. With air still flowing, put on RT Series respirator hood. Pull the hood over
your head until the neck cuff is securely around your neck.
NOTE
The RT3 and RT4 hoods have an adjustable velcro strap near the top of
the lens that allows the user to customize the curvature of the lens to
his/her personal preference. This strap may be removed if desired.
5. Make sure that the breathing tube is not twisted after donning.
6. Tuck inner bib of hood into shirt or protective clothing for additional splash
and overspray protection (see Figure 9).
7. Pull respirator outer bib over collar of shirt or protective clothing. Pull
the long outer bib down on the outside of clothing and secure with tie down
straps or tape (if employer operating procedures will allow.)
10. With breathing tube assembly attached to the hood, fasten belt at waist or
hip level and adjust for comfort.
11. Recheck air pressure and adjust if necessary.
12. With air flowing into your respirator, you are now ready to enter work
area.
Removing the RT Series Respirator
When finished working, leave work area wearing respirator and with air still
flowing. Once outside contaminated area, remove respirator and then discon-
nect the air supply hose using the quick-disconnect fittings.
WARNING
Do not put on or remove these respirators in a hazardous atmosphere
except for emergency escape purposes. Failure to heed these warnings
could result in death or serious injury.
