5.2 Specific hazards arising from the chemical
Excerpt from ERG Guide 149 [Substances (Self-Reactive)]: Self-decomposition, self-polymerization, or self-ignition may be triggered by heat, chemical reaction, friction or impact. May be ignited by heat, sparks or flames. Some may decompose explosively when heated or involved in a fire. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. May burn violently. Decomposition or polymerization may be self-accelerating and produce large amounts of gases. Vapors or dust may form explosive mixtures with air. (ERG, 2016)
5.3 Special protective actions for fire-fighters
Wear self-contained breathing apparatus for firefighting if necessary.
6.Accidental release measures

10.3 Possibility of hazardous reactions
FlammableAZODICARBONAMIDE is easily ignited and burns rapidly. Confined samples show a high rate of pressure rise during thermal decomposition, which produces carbon monoxide and nitrogen. Sensitive to temperatures exceeding 50\u00b0C. May be sensitive to exposure to light. Stable in bulk when stored for two weeks at temperatures up to 60\u00b0C. Slightly unstable in water suspension (showed 1.3% decomposition at 2 mg/mL over a two-week period at room temperature in the light but no decomposition at 5\u00b0C over a two-week period in the dark . Reacts with hot water to give nitrogen, carbon monoxide, and ammonia [Hawley]. Decomposes in hot hydrochloric acid. Incompatible with strong acids and bases, and with compounds of metals.
