Respirator Use - Bullard CC20E Manual Del Usuario

Do not use this respirator in poorly ventilated areas or confined spaces such as tanks, small rooms, tunnels, or
vessels unless the confined space iswell-ventilated, and contaminant concentrations are below the protection level
of the respirator. In addition, follow all procedures for confined space entry, operation, and exit as defined in
applicable regulations and standards.
Donning
Before using your CC20E Series respirator, assemble
the respirator using the instructions given in
Respirator Assembly Section. Before donning, make
sure there is no dirt, dust or contamination inside
the hood.
1. Connect the Bullard air supply hose to an air
source supplying clean breathable air. Turn on
breathing air source.
2. With air flowing, connect breathing tube assem-
bly to air supply hose (see Figure 12). Connect
quick-disconnect fitting on breathing tube
assembly to quick-disconnect coupler on air sup-
ply hose. Once fitting is secured, release
coupling sleeve to lock fittings together. Pull on
both hoses to make sure they are attached
securely. Check to assure air is flowing properly
into the hood.
3. Adjust air pressure at point-of-attachment to
within the approved pressure range (see Figure
13). See Breathing Air Pressure Table for
approved pressure ranges.
4. With air still flowing, put on CC20E Series respi-
rator hood, inserting chin first.
5. Position headband or hard hat for a comfortable
fit. See instructions for proper sizing.
6. If using an optional chin strap, pull elastic strap
under your chin. Adjust for a secure and com-
fortable fit.
7. Tuck inner bib of hood into shirt or protective
clothing for additional splash and overspray pro-
tection (see Figure 14).
8. Pull respirator outer bib over collar of shirt
or protective clothing. If you are using the
20SICNE model, pull the long outer bib down on
the outside of clothing and tie at the sides.
9. With breathing tube assembly attached to the
hood, fasten belt at waist or hip level and adjust
for comfort.
10. Recheck air pressure at the point-of-attachment.
Adjust if necessary.
11. With air flowing into your respirator, you are now
ready to enter work area.

When finished working, leave work area wear-
ing respirator and with air still flowing. Once
outside contaminated area, remove respirator
and then disconnect the air supply hose using
the quick-disconnect fittings.
DO NOT wear this respirator if any of the
following conditions exist:
• Atmosphere is immediately dangerous to
life or health (IDLH).
• You CANNOT escape without the aid of the
respirator.
• Atmosphere contains less than 19.5% oxy-
gen or is oxygen enriched.
• Work area is poorly ventilated.
• Unknown contaminants are present.
Pressure Gauge
• Contaminants are in excess of regulatory
requirements.
LEAVE work area immediately if:
• Any respirator component becomes dam-
aged.
• Airflow into respirator hood stops or slows
down.
• Air pressure gauge drops below the mini-
mum specified in the Breathing Air
Pressure Table.
• Breathing becomes difficult.
• You become dizzy, nauseous, too hot, too
cold or ill.
• You taste, smell or see contaminants
inside the respirator hood.
• Your vision becomes impaired.
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
the contaminated area could result in expo-
sure to contaminants.
