SECTION V. HEALTH HAZARD DATA
THRESHOLD LIMIT VALUE
(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.
