일반 설명
DIBROMODIFLUOROMETHANE is a colorless, nonflammable liquid. DIBROMODIFLUOROMETHANE may cause illness from ingestion and may be irritating to skin. If exposed to high temperatures DIBROMODIFLUOROMETHANE may emit toxic fumes. The primary hazard is the threat to the environment. Immediate steps should be taken to limit its spread to the environment. Since DIBROMODIFLUOROMETHANE is a liquid DIBROMODIFLUOROMETHANE can easily penetrate the soil and contaminate groundwater and nearby streams. DIBROMODIFLUOROMETHANE is used as a fire extinguishing agent.
