UN 1860: Vinyl fluoride, stabilized

49 CFR 172.101 Hazardous Materials Table·ERG 2024

DOT Classification and Shipping

UN 1860 is assigned the proper shipping name Vinyl fluoride, stabilized 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

Vinyl fluoride, stabilized appears as a colorless gas with a faint ethereal odor. Shipped as a confined liquid under its vapor pressure. Any leak can either be liquid or vapor. Contact with the liquid can cause frostbite. Easily ignited. Vapors are heavier than air. Can asphyxiate by the displacement of air. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket.
