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
conrmed you can then determine the lter cartridge to be used for the application, to make sure
that you are sufciently protected. Make sure that the area is well ventilated and that regular air
samples are taken to conrm the atmosphere stays within the levels recommended by OSHA
and other governing bodies. Follow the PX4 AIR® PAPR Instruction Manual for more details.
Supplied Air
Locate the air source in a clean air environment, always use a lter on the inlet of your air source.
Make sure the air source is somewhere that vehicles, forklifts, and other machinery are not
running near the air inlet, as this will cause carbon monoxide to be drawn into your air supply.
Always use suitable after coolers/dryers with lters and carbon monoxide alarms to ensure clean
breathable air is supplied at all times. A Radex® Airline Filter (04-900) and a GX4® Gas Monitor
(08-400) are recommended. 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 Specications G.7.1 (Grade D or higher) and as specied by Federal Law 42 CFR 84,
subpart J.84.141(b) and 29 CFR 1910.134 (i). The RPB® Z4® does not purify air or lter contaminants.
A carbon monoxide monitor must be used at all times.
Do not connect the respirator’s air supply hose to nitrogen, toxic gases,
inert gases or other non-breathable air sources. Check the air source
before using the respirator. This apparatus is not designed for use with mobile air supply systems i.e.
cylinders. Connecting the supply hose to a non-breathable air source will result in serious injury or
death.
BREATHING AIR SUPPLY HOSES AND FITTINGS
RPB® air supply hoses and ttings 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 specied in the breathing air
pressure table on page 14.
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 owing through it.
