Product Handling and Safety Information

Protective gloves, clothing and mask are recommended for product handling. Airborne fiber dust should always be kept down. Ceramic fiber may cause itching and irritation to skin and eyes by contact. If inhaled in sufficient amount of ceramic fiber, it may cause irritation to respiratory tract, scratchiness of the nose or throat, cough or chest discomfort. Ceramic fiber is classified in Group 2b (possible human carcinogen) by IARC. Based on animal study, it is a possible cancer hazard by prolonged heavy inhalation of this fiber. For detailed information, please refer to product SDS. (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 hamster.  The fibers used in those studies were specially sized to maximize rodent respirability.)
