CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Dichlorodifluoromethane appears as a colorless gas having a faint ethereal odor. Shipped as a liquid confined under its own vapor pressure. Contact with the unconfined liquid can cause frostbite. Both components are noncombustible. Can asphyxiate by the displacement of air. Exposure of the closed container to prolonged heat or fire can cause it to rupture violently and rocket. |
