RESPIRATOR OPERATION
AIR SOURCE
Powered Air
Check that the contaminated area is within
the limits of use for a Powered Air Purifying
Respirator and determine the type of
contamination. Once the contamination
level has been confirmed you can then
determine the filter cartridge to be used for
the application, to make sure that you are
sufficiently protected. Make sure that the
area is well ventilated and that regular air
samples are taken to confirm the atmosphere
stays within the levels recommended by
OSHA and other governing bodies. Follow
the PX4 PAPR Instruction Manual for more
details.
Supplied Air
Locate the air source in a clean air
environment, always use a filter on the inlet
of your air source. Do not park vehicles
beside your air inlet as this will cause carbon
monoxide to be drawn into your air supply.
Always use suitable after coolers / dryers
with filters and carbon monoxide alarms to
ensure clean breathable air is supplied at all
times. The air should be regularly sampled to
ensure that it meets Grade D requirements.
AIR QUALITY
This respirator must be supplied with clean
breathable air at all times. Breathable air must
at least meet the requirements for Type 1
gaseous air described in the Compressed Gas
Association Commodity Specifications G.7.1
(Grade D or higher) and as specified by Federal
Law 42 CFR 84, subpart J.84.141(b) and 29
CFR 1910.134 (i) the RPB
purify air or filter contaminants.

BREATHING AIR SUPPLY
HOSES AND FITTINGS
RPB
air supply hoses and fittings must be
®
used between the point of attachment and
the respirator breathing air connection at the
wearer's belt. The hose sections must be
within the correct length and the amount of
sections must be within the number specified
in the breathing air pressure table on page 10.
BREATHING AIR PRESSURE
The air pressure must be continually
monitored at the point of attachment. Air
pressure must be read from a reliable
pressure gauge whilst the respirator has
air flowing through it.
!WARNING!
Failure to supply the minimum required air
pressure at the point of attachment for the
length of air supply hose could result in
contaminants being inhaled as the pressure
in the helmet may become negative due
to peak inhalation flow when working at
very high work rates. The RPB
Breathing Air Pressure table on page 10
defines the air pressure ranges needed to
provide the respirator with a volume of air
which falls in the required range of 6-15cfm or
170-425 Its/min.
