PROTECTION PROVIDED AND LIMITATIONS

RESPIRATION

The RPB

Powered Air

The RPB
including t he Breathing Tube Assembly and the approved head top, is part of a NIOSH
approved powered air purifying respirator. As such, it signific antly reduces, but does not
completely eliminate, the breathing of contaminates by the respirator wearer. See the
instruction manual and approval label for the selected head top for NIOSH approval with the PX4
AIR®and the as signed protection factor. Specific protection depends on the filter selected for
use in the RPB® PX4 AIR® PAPR. It is approved to be used with the 03-985 High Efficiency
(HE) Filter and the 03-995 Organic Vapor/Acid Gas/High Efficiency (OV/AG/HE) Cartridge.

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.

In accordance with the above,



Perform a hazard analysis and select appropriate equipment for each activity. A



hazard analysis should be performed by a qualified person. Controls should be in
place as appropriate and a qualified person should determine what kind of respiratory,
face and eye, head, and hearing protection is appropriate for the intended activities
and environments of use. (For example, select a respirator appropriate to the specific
airborne hazards, with consideration of workplace and user factors and with an Assigned
Protection Factor (APF) that meets or exceeds the required level for employee protection,
select welding face and eye protection appropriate to the type of welding to be done, etc.)

As applicable, check your workplace safety program, respiratory protection program, and
standards and regulations for your activity or industry for related protection requirements,
and see this manual (Protection Provided and Limitations, page 4) and the head top
Instruction Manual for product specifications.
