metals, corrosive liquids or hazardous
gases.
8. Materials which may come into
contact with the wearer’s skin could
cause allergic reactions to susceptible
individuals.
9. Welding helmet worn over standard
spectacles may transmit impact, thus
create a hazard to the wearer.
10. The RPB®Z3™ Welding Helmet does
not provide hearing protection. Earplugs
or earmuffs must be properly tted when
exposed to noise levels that exceed the
OSHA permissible exposure levels.
11. Do not use this respirator until you
have been trained in the respirators
use, maintenance and limitations by
a qualied individual (appointed by
your employer) who has extensive
knowledge on the RPB®Z3™
Respirator. All training must be in
accordance with this Users Instruction
Manual.
12. Before using this respirator ensure your
employer has determined that airborne
contaminant concentrations do not
exceed those allowed by applicable
OSHA, EPA or NIOSH regulations and
recommendations for continuous ow
supplied air respirators. Federal law
requires that the employer measures
and monitors airborne contaminant
levels in the work area.
13. If this respirator is used in conned
spaces ensure the area is well ventilated
and that all contaminate concentrations
are below those recommended for this
respirator. Follow all procedures for
conned space entry, operation and exit
BEFORE WELDING
1. Ensure that the helmet is correctly
assembled and that it completely
blocks any accidental light. In the front,
light may enter the helmet only through
the viewing area of the autodarkening
welding lter.
2. Check the prescribed shade level for
your welding application and adjust
your autodarkening lter accordingly
(see the table with recommended shade
levels Pg 20).
3. Never place the helmet or the
autodarkening welding lter on hot
surfaces.
4. Scratched or damaged protection
screens should be regularly replaced
by genuine RPB®replacement parts.
Before using the new protection screen,
make sure to remove any additional
protection foil from both sides.

voids the NIOSH approval of the entire
respirator assembly.
16. Inspect all components of the respirator
daily for signs of damage or wear
and tear that may reduce the level of
protection originally provided.
1 7. Do not wear this respirator until you
have passed a complete physical exam
including a lung X-ray conducted by
qualied medical personnel.
18. This respirator, when properly tted and
used, signicantly reduces but does not
completely eliminate the breathing of
contaminates by the respirator wearer.
19. Be certain your employer has
determined that the breathing air source
provides at least a Grade D breathable
air as specied in the compressed gas
association commodity specication
G-7.1. The respirator must be supplied
with clean breathable air at all times.
A carbon monoxide monitor must be
used at all times. Contact your RPB®
distributor for a Radex 08-200 CO
Monitor. Do not connect the respirator’s
air supply hose to nitrogen, toxic gases,
inert gases or other unbreathable non
Grade D 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.
Failure to connect the supply hose to
the proper air source could result in
serious injury or death.

RESPIRATOR OPERATION
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®Z3™
Welding Helmet does not purify air or lter
contaminants.
When using a RPB®Z3™ Welding Helmet
Supplied Air Respirator. It is recommended to
use a Radex Airline Filter (p/n: 04-900) and
a GX4®Gas Monitor (p/n: 08-400).
AIR SOURCE
Supplied air
Locate the air source in a clean air
environment, always use a lter 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 lters 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.
Powered Air
Check that the contaminated area is within
the limits of the use of a Powered Air
Purifying Respirator and determine the type
of contamination. Once the contamination
level has been conrmed then you can
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®PAPR Instruction Manual for more
details.
BREATHING AIR SUPPLY
HOSES AND FITTINGS
RPB® Safety 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 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
owing 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 ow when working at very
high work rates. The RPB®Z3™ Breathing
Air Pressure table on page 9 denes 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.
