Warning
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.

respirator Use
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 assembly to air supply hose (see Figure
12). 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. 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 respirator hood, inserting chin first.
5. Position headband or hard hat for a comfortablefit. See instructions for proper sizing.
6. If using an optional chin strap, pull elastic strap under your chin. Adjust for a
secure and comfortable fit.
7. Tuck inner bib of hood into shirt or protective clothing for additional splash and
overspray protection (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.
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

Warning
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% oxygen or is oxygen enriched.
• Work area is poorly ventilated.
• Unknown contaminants are present.
• Contaminants are in excess of regulatory requirements.
LEAVE work area immediately if:
• Any respirator component becomes damaged.
• Airflow into respirator hood stops or slows down.
• Air pressure gauge drops below the minimum 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 exposure to
contaminants.
