| Physical Description |
Bromotrifluoromethane appears as a colorless, odorless gas at room conditions Shipped as a liquid confined under its own vapor pressure. Noncombustible. Nontoxic but can asphyxiate by the displacement of air. Contact with the unconfined liquid can cause frostbite by evaporative cooling. Exposure of the container to prolonged heat or fire can cause it to rupture violently and rocket. |

| Decomposition |
THE FIRE EXTINGUISHER HALON 1301 BEGINS TO DECOMP AT 400-500 DEG TO HALOGEN GASES, WHICH REACT WITH HYDROGEN TO FORM HYDROGEN HALIDES. IN OXYGEN, CARBON DIOXIDE, CARBONYL FLUORIDE & CARBONYL BROMIDE MAY FORM. HAZARDS FROM DECOMP PRODUCTS ARE NEGLIGIBLE AS COMPARED TO THOSE OF OTHER HAZARDS ASSOCIATED WITH A FIRE. |
