1-2. Breathing Air Hazards
The symbols shown below are used throughout this manual
to call attention to and identify possible hazards. When you
see the symbol, watch out, and follow the related instructions
to avoid the hazard. The safety information given below is
only a summary of the more complete safety information
found in the Principal Safety Standards listed in Section 1-4.
Read and follow all Safety Standards.
Only qualified persons should install, operate, maintain, and
repair this equipment. A qualified person is defined as one
who, by possession of a recognized degree, certificate, or
professional standing, or who by extensive knowledge, train-
ing and experience, has successfully demonstrated the
ability to solve or resolve problems relating to the subject
matter, the work, or the project and has received safety train-
ing to recognize and avoid the hazards involved.
During operation, keep everybody, especially children, away.
BREATHING UNFILTERED AIR can be
hazardous.
Welding produces fumes and gases. Misuse of the air
filtration system may expose you to fumes and gases
hazardous to your health.
D
Read and follow these instructions and the safety labels carefully.
The air filtration system helps protect the user from specific air-
borne contaminants but must be used correctly to be fully effective.
Have an industrial hygienist test the air in your facility to ensure the
air filtration system provides adequate protection from contami-
nants in your environment. If you have questions about the air
filtration system, see equipment NIOSH label and consult your
Safety Director and a certified Industrial Hygienist. For occupa-
tional use applications, employers must implement a written
respiratory protection program meeting the requirements of OSHA
29 CFR 1910.134 (USA) or CSA Z94.4 (Canada), and other sub-
stance specific requirements as applicable.
D
Do not use the air filtration system until you have been trained in its
proper operation by a qualified person.
D
Follow all applicable ANSI, OSHA, CSA, CGA, and other regulato-
ry guidelines pertaining to the use of air filtration systems.
D
Do not use the air filtration system where there is danger of fire or
explosion.
D
Do not use the air filtration system in applications immediately dan-
gerous to life or health (IDLH).
D
Do not enter a hazardous area until you are sure the air filtration
system is assembled correctly, and working properly.
D
Dangerous contaminants may not smell or be visible. Leave the
area immediately if you notice any of the following:
Breathing becomes difficult.
. . .
You experience dizziness, impaired vision, or eye, nose, or
. . .
mouth irritation.
The air supply smells or tastes unusual.
. . .
The air supply equipment alarm sounds.
. . .
The equipment is damaged.
. . .
Air flow decreases or stops.
. . .
If you think the equipment is not supplying adequate protection.
. . .
Do not remove the equipment until you are in a safe area.
D
Before each use, inspect air filtration system for damage and verify it
operates properly. Before using the air filtration system, test the air
flow to verify the system is receiving an adequate volume of air. Clean
and maintain the air filtration system according to the manufacturer’s
instructions.
D
Do not use the air filtration system without all components or with
the air supply turned off because hazardous levels of oxygen and
carbon dioxide can accumulate in the helmet.
D
Do not repair, modify, or disassemble the air filtration system or use
with parts or accessories not supplied by the manufacturer. Use only
those components that are part of the NIOSH-approved assembly.
D
Breathable air must meet the requirements of Grade D breathing
air as described in Compressed Gas Association Commodity
Specification G.7.1 (United States) or CSA Standard Z180.1
(Canada). Use appropriate filters and carbon monoxide alarms to
ensure breathable air is supplied.
D
Have a qualified person test the breathing air to ensure it meets
Grade D requirements. Breathing air testing shall be done in accor-
dance with a written respirator protection program (prepared by a
qualified person) specific to the workplace.
D
Locate the compressed air source in a clean environment that is free
from toxic fumes and gases and away from other sources of contami-
nation, such as building exhaust vents and engine-powered vehicles
and equipment (including generators). Be sure inlet on compressed
air source is properly filtered to remove contaminants.
D
Use only air line couplings designed for the supplied air system; air
couplings must be incompatible with outlets for other gas systems.
D
Operate air filtration system within specified air pressures and air
hose lengths. The air supply system (air supply lines, fittings, fil-
ters, couplings, air pump/tanks) must be able to deliver sufficient
air volume within safe limits, 125 psig (862 kPa) maximum. If cor-
rect pressure is not maintained, negative air pressure can develop
in the helmet and create a risk of contaminants being inhaled. Also,
unless removed by filters, oil, water, and other contaminants could
flow downstream from the compressed air supply and adversely
affect the supplied air respirator’s performance. While air is flow-
ing, use a reliable pressure gauge to continually monitor air
pressure at the air source connection point.
D
To ensure adequate cooling of supply air, follow air compressor manu-
facturer’s recommendations when selecting air hose length. Do not
use an air compressor that supplies air warmer than 160
F (71
C);
supply air exceeding this temperature will degrade the air hose, which
could adversely affect the supplied air respirator’s performance.
