UN 130: Lead styphnate, wetted

49 CFR 172.101 Hazardous Materials Table·ERG 2024

DOT Classification and Shipping

UN 130 is assigned the proper shipping name Lead styphnate, wetted in the U.S. DOT Hazardous Materials Table (49 CFR 172.101). It is classified as a Class 1.1A Explosive material. Required label(s): 1.1.

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 112)

Hazards: May explode or be projected if heated. Fragments may travel great distances. Fire may produce irritating or toxic gases.

Fire: DO NOT fight fire when it reaches cargo. Evacuate area and let burn. Fight fire from maximum distance.

Spill: Do not touch or walk through spilled material. Isolate spill area immediately.

Chemical and Physical Properties

Lead styphnate, [wetted with >= 20 % water or mixture of alcohol and water] appears as a slurry or wet mass of orange-yellow crystals. Must be shipped wet with at least 20% water or water and denatured ethyl alcohol mixture. May explode due to shock, heat, flame, or friction if dried. Used as an initiating explosive. The primary hazard is the blast of an instantaneous explosion and not flying projectiles and fragments.
