** 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 objectives and criteria underlying each of
these OEL decisions also vary. The evaluation of occupational exposure limits and determining
their relative applicability to the workplace is best performed, on a case-by-case basis, by a
qualified Industrial Hygienist.

ENGINEERING CONTROLS
Use engineering controls such as local exhaust ventilation, point of generation dust collection,
down draft work stations, emission controlling tool designs, and materials handling equipment
designed to minimize airborne fiber emissions.
