POSSIBLE CANCER HAZARD BY INHALATION. (See Section 11 for more information) 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.
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).
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. 7. HANDLING AND STORAGE 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.
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.
control exposures to airborne fiber and the potential presence of crystalline silica. If exposure levels are known, the respiratory protection chart provided above may be applied. Potential exposure to other airborne contaminants should be evaluated by a qualified Industrial Hygienist for the selection of appropriate respiratory protection and air monitoring. Skin Protection: Wear gloves, head coverings and full body clothing as necessary to prevent skin irritation.
The University of Cincinnati is conducting an ongoing epidemiologic investigation. The evidence obtained from employees in U. S. RCF manufacturing facilities is as follows: 1) There is no evidence of any fibrotic lung disease (interstitial fibrosis) from evaluations of chest X-rays. 2) There is no evidence of an elevated incidence of lung disease among RCF manufacturing employees.
No ecological concerns have been identified. 13. DISPOSAL CONSIDERATIONS WASTE MANAGEMENT To prevent waste materials from becoming airborne during waste storage, transportation and disposal, a covered container or plastic bagging is recommended. DISPOSAL RCF, as manufactured, is not classified as a hazardous waste according to Federal regulations (40 CFR 261). Any processing, use, alteration or chemical additions to the product, as purchased, may alter the disposal requirements.
