UN 1510: Tetranitromethane

49 CFR 172.101 Hazardous Materials Table·ERG 2024

DOT Classification and Shipping

UN 1510 is assigned the proper shipping name Tetranitromethane in the U.S. DOT Hazardous Materials Table (49 CFR 172.101). It is classified as a Class 5.1 Oxidizer material, Packing Group I. Required label(s): 5.1, 6.1.

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 143)

Hazards: May explode from heat or contamination. Strong oxidizer. May ignite combustibles.

Fire: Flood with water from distance. Cool containers. Evacuate area if fire reaches cargo.

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

Chemical and Physical Properties

Tetranitromethane appears as a pale yellow liquid. Irritates skin and respiratory tract. Very toxic by inhalation. Difficult to ignite. Burns at a steady rate once ignited. Under prolonged exposure to fire or heat containers may rupture violently and rocket Produces toxic oxides of nitrogen during combustion.
