concentrations within the 0.5 f/cc REG, the use of appropriate respiratory protection, pursuant to
the requirements of OSHA Standards 29 CFR 1910.134 and 29 CFR 1926.103, is recommended.
The following information is provided as an example of appropriate respiratory protection for
aluminosilicate fibers. The evaluation of workplace hazards and the identification of appropriate
respiratory protection is best performed, on a case by case basis, by a qualified Industrial
Hygienist.
MANUFACTURER’S RESPIRATORY PROTECTION RECOMMENDATIONS
WHEN HANDLING RCF PRODUCTS
Respirable Airborne Fiber Concentration
(levels are 8-hr. time-weighted averages)
Respirator Recommendation
†
Not yet determined but expected to be below
5.0 f/cc based on operation
Half-face, air purifying respirator equipped with
a NIOSH certified P100 particulate filter
cartridge
"Reliably" less than 0.5 f/cc
Optional
0.5 f/cc to 5.0 f/cc
Half-face, air purifying respirator equipped with
a NIOSH certified P100 particulate filter
cartridge
5.0 f/cc to 25 f/cc
Full-facepiece, air purifying respirator equipped
with a NIOSH certified P100 particulate filter
cartridge or PAPR
Greater than 25 f/cc
PAPR with tight-fitting full facepiece or a
supplied air respirator in continuous flow mode
When individual workers request respiratory
protection as a matter of personal comfort or
choice where exposures are "reliably" below 0.5
f/cc
A NIOSH certified respirator, such as a
disposable particulate respirator, or respirators
with filter cartridges rated N95 or better
†
The P100 recommendation is a conservative default choice; in some case, solid arguments can
be made that other respirator types (e.g., N95, R99, etc.) may be suitable for some tasks or work
environments. The P100 recommendation is not designed to limit informed choices, provided that
respiratory protection decisions comply with 29 CFR 1910.134.
Other Information:
•
Concentrations based upon an eight-hour time weighted average (TWA) as determined
by air samples collected and analyzed pursuant to NIOSH method 7400 (B) for airborne
fibers.
•
The manufacturer recommends the use of a full-facepiece air purifying respirator
equipped with an appropriate particulate filter cartridge during furnace tear-out events
and the removal of used RCF to control exposures to airborne fiber and the potential
presence of crystalline silica. If exposure levels are known, the respiratory protection
chart provided above may be applied.
•
Potential exposure to other airborne contaminants should be evaluated by a qualified
Industrial Hygienist for the selection of appropriate respiratory protection and air
monitoring.
