UN 1514: Zinc nitrate

DOT Classification and Shipping

UN 1514 is assigned the proper shipping name Zinc nitrate in the U.S. DOT Hazardous Materials Table (49 CFR 172.101). It is classified as a Class 5.1 Oxidizer material, Packing Group III. Required label(s): 5.1.

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 140)

Hazards: May cause fire or explosion. May accelerate burning. May explode from heat or contamination.

Fire: Use flooding water. Cool containers. Do not use dry chemical on large fires (ineffective).

Spill: Keep combustibles away. Do not touch. Use water spray to reduce dust.

Chemical and Physical Properties

Zinc nitrate is a colorless crystalline solid. Noncombustible, but accelerates the burning of combustible materials. If large quantities are involved in a fire or the combustible material is finely divided, an explosion may result. Prolonged exposure to fire or heat may result in an explosion. Toxic oxides of nitrogen are produced in fires involving this material. It is used as a catalyst in the manufacture of other chemicals, in medicine, and in dyes.
