connect the other end of the respirator hose to a respirable
air source. If longer hose is required, it must be a NIOSH-
approved Clemco respirator hose extension. Any 25 foot,
50 foot and 100 foot respirator hoses can be added in any
combination to produce the maximum total length as noted
in the table in Section 4.2.4.

AIR SUPPLY
! WARNING
Air supplied to this respirator system is critical to
the safety of the user. Read this section carefully.
Poor quality air will cause serious respiratory
injury or death to the user. See Toxic Dust Poi-
soning Warning in Section 1.3.
4.1
Air Quality
4.1.1
The quality of air supplied to the respirator is
extremely critical to the safety of the user. Special care
must also be taken to avoid accidental connection to any
other gas lines; such as, oxygen, acetylene, or nitrogen.
! WARNING
Never connect a breathing air line to an air source
that has not been tested for gas and particulate
contamination. The presence of unacceptable
levels of carbon monoxide (CO) or other gases in
the breathing air will cause death to the user.
! WARNING
Do not use piston type, oil-bath, compressors for
breathing air. These compressors could produce
dangerous levels of carbon monoxide, which will
cause death to the user.
4.1.2
Breathing air used to supply the respirator must be
respirable breathing air and contain no less than 19.5
volume-percent of oxygen. Breathing air shall also meet
the requirements for Grade D or higher quality, as de-
scribed in Compressed Gas Association Commodity Speci-
fication pamphlet G-7.1., titled Commodity Specification
For Air, published by Compressed Gas Association Inc.,
Arlington, VA. (42 CFR Chapter 1).
4.1.3
Prior to using the respirator, read the owner’s
manual and all instructions, labels, and warnings relating
to the compressed air source. Take special care to abide
by all warnings from the compressor manufacturer regard-
ing compressor use.
4.1.4
A breathing air type compressor must be used.
The compressor must be equipped with necessary safety
and monitoring devices, plus suitable in-line air filters and
purifying equipment to assure breathing air quality. [Refer-
ence OSHA Regulations 29 CFR 1910.134 (d), and 29
CFR 1926.103 (f)].
4.1.5
If an oil-lubricated compressor is used, it must be
equipped with a high-temperature alarm or carbon monox-
ide (CO) alarm, or both. If only a high-temperature alarm
is used, the air from the compressor must be tested
frequently for the presence of carbon monoxide. [Refer-
ence OSHA Regulations 29 CFR 1910.134 (d) and 29 CFR
1926.103 (f)].
4.1.6
Regardless of the air compressor type, precau-
tions must be taken to prevent contaminants from entering
through the compressor intake. The compressor inlet must
be located away from all sources of toxic contaminants
including carbon monoxide, which is found in engine
exhaust, and in any form of combustion. No vehicles
should be allowed near the compressor intake. Contami-
nants can enter respiratory equipment through the com-
pressor air inlet. This inlet must not be located near any
exhaust system outlet, ventilation flue, or source of fumes
or particles of any kind.
4.1.7
The precautions described above also apply to
portable compressors. In addition, in the case of engine-
driven compressors, precautions must be taken to prevent
engine exhaust gases from entering the air intake of the
compressor. Compressor engine exhaust should be piped
to a location safely downwind from the compressor air
intake. Compressors vary in design and operation; there-
fore, it is important that users carefully read the
manufacturer’s operation and maintenance instructions
before making modifications.
4.1.8
An appropriate air filter must be installed and
regularly maintained to remove objectionable odors, as
well as oil mist, water, pipe scale and other particulate
matter. Refer to OSHA Regulation 1910.94(6). The Clemco
CPF Air Filter complies with the regulation, and provides
the pressure reducing valve referred to in the regulation.
4.1.9
It is the owner’s and user’s responsibility to check
the air supply. This includes the compressor, carbon
monoxide alarms, air filters, and shut-down devices. An
overheated compressor, or one that is in poor mechanical
condition, may produce carbon monoxide. A carbon
