3.3
Breathing Tube Assembly
CAUTION
Note the directional flow arrows on the labels at
both ends of the breathing tube. The flow
arrows indicate the direction of air flow to the
helmet. Flow arrows must point toward the
helmet. Failure to properly attach the breathing
tube may damage the tube's acoustical foam,
which will block air flow, or it may increase
noise levels beyond OSHA limits.
3.3.1
The breathing tube has a clamped-on end and a
molded-on end. Attach the clamped-on end to the
threaded air inlet fitting at the back of the helmet as
shown in Figure 2. Do not over-tighten; hand-tight is
sufficient.
3.3.2
Attach the molded-on swivel connector to the
constant-flow connector.
Figure 2
CAUTION
Use the handle to carry or hang the respirator.
Never hold, carry or hang the respirator by the
breathing tube. Mishandling the respirator in
this manner may damage the tube or helmet
inlet. Any leaks or breaks in the breathing tube
will alter the air flow through the respirator and
affect user’s safety and comfort.
3.4 Respirator
Hose
WARNING
OSHA regulations 29 CFR 1910 and 29 CFR
1926 require that respirator air line couplers be
incompatible with air lines for non-respirable
use. This incompatibility prevents inadvertent
supply of respirators with potentially
hazardous, non-respirable gases or oxygen. It
is the employer's or facility owner's
responsibility to comply with the regulation.
3.4.1
Respirator hose must be NIOSH-approved
Clemco 1/2
"
ID respirator hose.
3.4.2
If longer hose is required, it must be a NIOSH-
approved Clemco 1/2
"
respirator hose extension. Use
50-foot or 100-foot Clemco respirator hoses in any
combination as noted in the table in Section 4.2, not to
exceed 300 ft. or three individual hose lengths.
3.4.3
Attach the female disconnect end of the
respirator hose to the constant-flow connector. The male
end attaches to the ambient air pump.
