CHRONIC EFFECT
There has been no increased incidence of respiratory disease in studies examining occupationally exposed workers. In
animal studies, long term laboratory exposure to doses hundreds of times higher than normal occupational exposures
has produced fibrosis, lung cancer and mesothelioma in rats or hamsters. The fibers used in those studies were
specially sized to maximize rodent respirability.
OTHER POTENTIAL EFFECTS
TARGET ORGANS:
Respiratory Tract (nose and throat), Eyes, Skin
RESPIRATORY TRACT (nose and throat) IRRITATION:
If inhaled in sufficient quantity, may cause temporary, mild mechanical irritation to respiratory tract. Symptoms may include
scratchiness of the nose or throat, cough or chest discomfort.
EYE IRRITATION:
May cause temporary, mild mechanical irritation. Fibers may be abrasive; prolonged contact may cause damage to the outer
surface of the eye.
SKIN IRRITATION:
May cause temporary, mild mechanical irritation. Exposure may also result in inflammation, rash or itching.
GASTROINTESTINAL IRRITATION:
Unlikely route of exposure.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE:
Pre-existing medical conditions, including dermatitis, asthma or chronic lung disease may be aggravated by exposure;
individuals who have a history of allergies may experience greater amounts of skin and respiratory irritation.
HAZARD CLASSIFICATION
Although studies, involving occupationally exposed workers, have not identified any increased incidence of respiratory
disease, results from animal testing have been used as the basis for hazard classification. In each of the following
cases, the conclusions are qualitative only and do not rest upon any quantitative analysis suggesting that the hazard
actually may occur at current occupational exposure levels.
The International Agency for Research on Cancer (IARC) confirmed in October 2001 that Group 2B (possible human
carcinogen based on sufficient evidence of carcinogenicity in animals but inadequate evidence in humans) continues to be the
appropriate classification for refractory ceramic fiber.
The Seventh Annual Report on Carcinogens (1994), prepared by the National Toxicology Program (NTP), classified
respirable RCF and glasswool as substances reasonably anticipated to be carcinogens.
The American Conference of Governmental Industrial Hygienists (ACGIH) has classified RCF as “A2-Suspected Human
Carcinogen.”
The Commission of The European Communities (DG XI) has classified RCF as a substance "that should be regarded as if
it is carcinogenic to man."
The State of California , pursuant to Proposition 65, The Safe Drinking Water and Toxic Enforcement Act of 1986, has listed
"ceramic fibers (airborne fibers of respirable size)" as a chemical known to the State of California to cause cancer.
The Canadian Environmental Protection Agency (CEPA) has classified RCF as "probably carcinogenic" (Group 2).
The Canadian Workplace Hazardous Materials Information System (WHMIS) – RCF is classified as Class D2A - Materials
Causing Other Toxic Effects.
The Hazardous Materials Identification System (HMIS) –
Health 1* Flammability 0 Reactivity 0 Personal Protection Index: X (Employer Determined)
