SPILL PROCEDURES
Avoid creating airborne dust. Dust suppressing cleaning methods such as wet sweeping or vacuuming should be
used to clean the work area. If vacuuming, the vacuum must be equipped with a HEPA filter. Compressed air or
dry sweeping should not be used for cleaning.
STORAGE
Store in original container in a dry area. Keep container closed when not in use.
HANDLING
Handle ceramic fiber carefully. Limit use of power tools unless in conjunction with local exhaust. Use hand tools
whenever possible. Frequently clean the work area with HEPA filtered vacuum or wet sweeping to minimize the
accumulation of debris. Do not use compressed air for clean-up.
EMPTY CONTAINERS
Product packaging may contain residue. Do not reuse.
EXPOSURE GUIDELINES
*There is no specific regulatory standard for RCF in the U.S. OSHA’s“Particulate Not Otherwise Regulated
(PNOR)”standard [29 CFR 1910.1000, Subpart Z, Air Contaminants] applies generally; Total Dust 15 mg/m³;
Respirable Fraction 5 mg/m³.
**The Refractory Ceramic Fibers Coalition (RCFC) has sponsored comprehensive toxicology and epidemiology
studies to identify potential RCF-related health effects [see Section 11 for more details], consulted experts familiar
with fiber and particle science, conducted a thorough review of the RCF-related scientific literature, and further
evaluated the data in a state-of-the-art quantitative risk assessment. Based on these efforts and in the absence of
an OSHA PEL, RCFC has adopted a recommended exposure guideline, as measured under NIOSH Method
7400 B. The manufacturers’REG is intended to promote occupational health and safety through prudent
exposure control and reduction and it reflects relative technical and economic feasibility as determined by
extensive industrial hygiene monitoring efforts undertaken pursuant to an agreement with the U.S. Environmental
Protection Agency.
OTHER OCCUPATIONAL EXPOSURE LEVELS (OEL)
RCF-related occupational exposure limits vary internationally. Regulatory OEL examples include: Australia –0.5
f/cc; Austria –0.5 f/cc; Canada – 0.5 to 1.0 f/cc; Denmark – 1.0 f/cc; France –0.6 f/cc; Germany – 0.5 f/cc;
Netherlands– 1.0 f/cc; New Zealand – 1.0 f/cc; Norway – 2.0 f/cc; Poland – 2.0 f/cc; Sweden – 1.0 f/cc; United
Kingdom– 2.0 f/cc. Non-regulatory OEL examples include: ACGIH TLV 0.2 f/cc; RCFC REG 0.5 f/cc. The
