(c) Individual protection measures, such as personal protective equipment
Skin Protection
Wear personal protective equipment (e.g gloves), as necessary to prevent skin irritation. Washable or disposable
clothing may be used. If possible, do not take unwashed clothing home. If soiled work clothing must be taken
home, employees should be informed on best practices to minimize non-work dust exposur
(e.g., vacuum clothes
before leaving the work area, wash work clothing separatel
, and rinse washer before washing other household
clothes).
Eye Protection
s necessar
, wear goggles or safety glasses with side shield
.
Respiratory Protection
When engineering and/or administrative controls are insufficient to maintain workplace concentrations below the
0.5 f/cc REG or a regulatory OEL, the use of appropriate respiratory protection, pursuant to the requirements of
OSHA Standards 29 CFR 1910.134 and 29 CFR 1926.103, is recommended.
NIOSH certified respirator with a
filter efficiency of at least 95% should be used. The 95% filter efficiency recommendation is based on NIOSH
respirator selection logic sequence for exposure to manmade mineral fibers. Pursuant to NIOSH
recommendations, N-95 respirators are appropriate for exposures up to 10 times the NIOSH Recommended
Exposure Limit (REL). With respect to RCF, both the NIOSH REL and the industry REG have been set at 0.5
fibers per cubic centimeter of air (f/cm
3
).
ccordingl
, N-95 would provide the necessary protection for exposure
up to 5 f/cm
3
. Further, the Respirator Selection Guide published by 3M Corporation, the primary respirator
manufacturer, specifically recommends use of N-95 respirators for RCF exposures. In cases where exposures
are known to be above 5.0 f/cm
3
, 8 hour TWA, a filter efficiency of 100% should be used. Other factors to
consider are the NIOSH filter series N, R or P -- (N) Not resistant to oil, (R) Resistant to oil and (P) oil Proof.
These recommendations are not designed to limit informed choices, provided that respiratory protection decisions
comply with 29 CFR 1910.134.
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.
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.
