local (e.g., state, provincial), or military standards and regulations and consensus standards
such as ANSI and CSA. There are also requirements specific to particular contaminants, e.g.
silica (see rpbsafety.com for more information), asbestos, organic pathogens, etc. Know which
requirements apply to your location and industry.
Have appropriate safety programs in place.
Have and follow:
A workplace safety program.
A written respiratory protection program in accordance with applicable standards and
regulations (e.g., OSHA 29 CFR 1910.134; ANSI/ASSE Z88.2; CSA Z94.4, etc.).
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,

6
PX5 PAPR®
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,
