HazardClass 1.1D

STYPHNIC ACID Standards and Recommendations

DOT Classification: EXPLOSIVE 1.1D; Label: EXPLOSIVE 1.1D

STYPHNIC ACID Specification

General Description :A yellowish, crystalline solid. May explode under exposure to heat or fire. Primary hazard is blast of an instantaneous explosion, not flying projectiles or fragments. Used as a priming agent. Very sensitive to heat. Water is added to lessen the explosion hazard.
Reactivity Profile :Aromatic nitro compounds, such as Trinitroresorcinol, range from slight to strong oxidizing agents. If mixed with reducing agents, including hydrides, sulfides and nitrides, they may begin a vigorous reaction that culminates in a detonation. The aromatic nitro compounds may explode in the presence of a base such as sodium hydroxide or potassium hydroxide even in the presence of water or organic solvents. The explosive tendencies of aromatic nitro compounds are increased by the presence of multiple nitro groups.
Health Hazard :Fire may produce irritating, corrosive and/or toxic gases.
Fire Hazard : Styphnic acid (82-71-3) may explode and throw fragments 1600 meters (1 mile) or more if fire reaches cargo.
