instructions to azodicarbonamide

general instructions
Yellow to orange powder. Insoluble in water and common solvents. Soluble in dimethyl sulfoxide. non-toxic.
air and water reaction
Highly flammable. Insoluble in water. Dust may form explosive mixtures in air.
fire hazardazodicarbonamide 
From ERG Guideline 149 [Substances (self-reactive)]:

Heat, chemical reaction, friction or shock may initiate self-decomposition, self-polymerization or spontaneous combustion. May be ignited by heat, sparks or flames. Some may decompose explosively when heated or exposed to fire. Those marked with (P) may polymerize explosively when heated or exposed to fire. May burn violently. Decomposition or polymerization may self-accelerate and produce large quantities of gas. Vapors or dust may form explosive mixtures with air. (ERG, 2020)
health hazard
azodicarbonamide From ERG Guideline 149 [Substances (self-reactive)]:

Inhalation or exposure to vapours, substance or decomposition products may result in serious injury or death. May produce irritating, toxic and/or corrosive gases. Runoff of firefighting water or dilution water may cause environmental pollution. (ERG, 2020)
reactive profile
Azodicarbonamide is easily ignited and burns rapidly. The airtight sample exhibited a higher rate of pressure rise during thermal decomposition, resulting in the generation of carbon monoxide and nitrogen. Sensitive to temperatures above 122°F. May be sensitive to light. Bulk stable when stored at temperatures up to 140°F for two weeks. Slightly unstable in aqueous suspension (shows 1.3% decomposition at 2 mg/mL over two weeks in light at room temperature but no decomposition in two weeks at 41°F in the dark (NTP, 1992). With hot water Reaction produces nitrogen, carbon monoxide and ammonia [Hawley]. Decomposes in hot hydrochloric acid. Incompatible with strong acids and bases and metal compounds.
