UN 1467: Guanidine nitrate

49 CFR 172.101 Hazardous Materials Table·ERG 2024

DOT Classification and Shipping

UN 1467 is assigned the proper shipping name Guanidine 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

Guanidine nitrate appears as a white crystalline solid. Soluble in water. Takes some effort to ignite but once ignited it burns with increasing vigor as the fire progresses. If contaminated with combustible materials it accelerates their burning. Prolonged exposure to fire or heat may result in an explosion. Produces toxic oxides of nitrogen during combustion.
