(See Section III)
EFFECTS OF OVER EXPOSURE
• EYE - Avoid contact with eyes. Slightly to moderately irritating. Abrasive action may cause damage to outer
surface of eye.
• INHALATION - May cause respiratory tract irritation. Repeated or prolonged breathing of particles of respirable
size may cause inflammation of the lung leading to chest pain, difficult breathing, coughing and possible fibrotic
change in the lung (Pneumoconiosis). Pre-existing medical conditions may be aggravated by exposure:
specifically, bronchial hyper-reactivity and chronic bronchial or lung disease.
• INGESTION - May cause gastrointestinal disturbances. Symptoms may include irritation and nausea, vomiting
and diarrhea.
• SKIN - Slightly to moderate irritating. May cause irritation and inflammation due to mechanical reaction to sharp,
broken ends of fibers.
EXPOSURE TO USED CERAMIC FIBER PRODUCT
Product which has been in service at elevated temperatures (greater than 1800ºF/982ºC) may undergo partial
conversion to cristobalite, a form of crystalline silica which can cause severe respiratory disease
(Pneumoconiosis). The amount of cristobalite present will depend on the temperature and length of time in
service. (See Section IX for permissible exposure levels).
SPECIAL TOXIC EFFECTS
The existing toxicology and epidemiology data bases for RCF's are still preliminary. Information will be updated as
studies are completed and reviewed. The following is a review of the results to date:
EPIDEMIOLOGY
At this time there are no known published reports demonstrating negative health outcomes of workers exposed to
refractory ceramic fiber (RCF). Epidemiologic investigations of RCF production workers are ongoing.
1) There is no evidence of any fibrotic lung disease (interstitial fibrosis) whatsoever on x-ray.
2) There is no evidence of any lung disease among those employees exposed to RCF that had never smoked.
