UN 2419: Bromotrifluoroethylene

DOT Classification and Shipping

UN 2419 is assigned the proper shipping name Bromotrifluoroethylene in the U.S. DOT Hazardous Materials Table (49 CFR 172.101). It is classified as a Class 2.1 Flammable Gas material. Required label(s): 2.1.

Packing group indicates the degree of danger within a hazard class: PG I is high danger, PG II medium, PG III low. The proper shipping name, hazard class, UN number, and packing group together form the basic shipping description that must appear on shipping papers and, where required, on the package and placard.

Emergency Response (ERG Guide 116)

Hazards: May polymerize explosively when heated or involved in fire. Extremely flammable. BLEVE risk.

Fire: Fight fire from maximum distance. Do not extinguish unless flow stopped. Cool containers with water.

Spill: Eliminate all ignition sources. Stop leak if safe.

Chemical and Physical Properties

Bromotrifluoroethylene appears as a colorless gas (boiling point -2 to 0 °C) shipped in cylinders or, if polymerized, a liquid. Heating the containers of gas may cause them to rupture violently and rocket. Polymeric bromotrifluoroethylene is a clear oily liquid of widely variable viscosity and density.
