CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Dibromodifluoromethane is a colorless, nonflammable liquid. It may cause illness from ingestion and may be irritating to skin. If exposed to high temperatures it 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 it is a liquid it can easily penetrate the soil and contaminate groundwater and nearby streams. It is used as a fire extinguishing agent. |
