CHEMICAL AND PHYSICAL PROPERTIES
| Physical Description | Bromine pentafluoride appears as a colorless, fuming liquid with a pungent odor. Used to make other chemicals and in rockets. Very toxic by inhalation. Corrosive to metals and tissue. Will accelerate the burning of combustible material. If the containers are involved in a fire they may rupture violently and rocket. |
