SUPPLY
WARNING
Air supplied to this respirator system is critical
to the safety of the user. Read this section
carefully. Poor quality air or low air volume will
cause serious respiratory injury or death to the
user. See Toxic Dust Poisoning Warning in
Section 1.5.
WARNING
This respirator is intended for use with (low
pressure) ambient air pumps. Do not use
compressors or high pressure cylinders
(bottles) as an air source for this respirator. Air
supplied from compressors poses hazards,
especially from carbon monoxide that are not
covered in these instructions. High pressure
cylinders require special knowledge for their
use and compliance, details of which are not
covered in these instructions.
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.
DANGER
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, or oxygen deficiency in
breathing air will cause death to the user.
4.1.2
The employer is responsible for ensuring that
breathing air shall meet the requirements for Grade D or
higher quality, as described in Compressed Gas
Association Commodity Specification pamphlet G-7.1.,
titled Commodity Specification For Air, published by
Compressed Gas Association Inc., Chantilly, VA.

(29 CFR 1910.134 (i)).
4.1.3
Limiting characteristics of Grade D air, at the
time of publication of this manual are as follows:
Carbon Dioxide ............. maximum of 1000 ppm
Carbon Monoxide .............. maximum of 10 ppm
Odor ................................. *No pronounced odor
Oil (hydrocarbons) ............. maximum of 5 mg/m
3
Oxygen ............................. between 19.5 - 23.5%
* Specific measurement of odor in gaseous air is
impractical. Air may have a slight odor but the
presence of a pronounced odor renders the air
unsatisfactory.
4.1.4
Prior to using the respirator, read the owner’s
manual and all instructions, labels, and warnings relating
to the ambient air pump.
WARNING
The air pump must be located where Grade D or
higher quality respirable air is ensured. If air
quality at the pump’s intake cannot be assured,
use an intake hose extension to draw air from
an area where clean, respirable air is certain.
Any toxic air entering the pump will enter the
respirator and will cause severe illness or death
to the user.
4.1.5
Take precautions to prevent contaminants from
entering through the air pump's inlet filter. Locate the air
pump's inlet filter away from all sources of contaminants
including carbon monoxide, which is found in engine
exhaust, and in any form of combustion. Place the pump
in an area away from vehicle traffic. Do not locate the
pump's inlet filter near any exhaust system outlet,
ventilation flue, or source of fumes or particles of any
kind. If the ambient air pump cannot be placed in an
area where respirable air can be guaranteed, use an air
inlet extension hose as specified by the pump
manufacturer to bring air from an area where clean
respirable air is ensured.

Air Volume and Pressure
4.2.1
LP respirators are for use with ambient pumps,
which provide 6 to 20 cfm of Grade D air at pressures
shown in table in Section 4.2.2. Maintaining the correct
operating pressure at the point of attachment ensures
the correct air flow to the respirator.
4.2.2
Use the following table to determine the
minimum and maximum pressure settings and maximum
