Excerpt from ERG Guide 150 [Substances (Self-Reactive / Temperature Controlled)]:

Highly flammable. Finely dispersed particles form explosive mixtures in air. Risk of fire and explosion when dissolving in organic solvents. Explosive.

Forms hydrogen cyanide in the body; [Merck Index] Decomposed by warming forming toxic fumes such as tetramethylsuccinonitrile and cyanide; May decompose explosively from heating, shock, friction, or concussion; May cause CNS and liver effects; [ICSC] May form explosive mixture of dust in air; May self-decompose or self-ignite from heat, chemical reaction, or impact; [CAMEO] Effects in high-dose animal studies include toxicity to liver and kidneys; [eChemPortal: SIDSUNEP] Highly flammable; May explode from shock, friction, fire, or other source of ignition; May cause irritation; Targets the CNS, liver, and kidneys; [MSDSonline] See NITRILES.

Self-decomposition or self-ignition may be triggered by heat, chemical reaction, friction or impact. Self-accelerating decomposition may occur if the specific control temperature is not maintained. These materials are particularly sensitive to temperature rises. AZODIISOBUTYRONITRILE is an azo compound. Azo, diazo, azido compounds can detonate. This applies in particular to organic azides that have been sensitized by the addition of metal salts or strong acids. Toxic gases are formed by mixing materials of this class with acids, aldehydes, amides, carbamates, cyanides, inorganic fluorides, halogenated organics, isocyanates, ketones, metals, nitrides, peroxides, phenols, epoxides, acyl halides, and strong oxidizing or reducing agents. Flammable gases are formed by mixing materials in this group with alkali metals. Explosive combination can occur with strong oxidizing agents, metal salts, peroxides, and sulfides.

Decomposes on warming. This produces toxic fumes of tetramethylsuccinonitrile (see ICSC 1121) and cyanide. May decompose explosively on shock, friction or concussion. May explode on heating. Reacts violently with alcohols, oxidants, ketones such as acetone, aldehydes and hydrocarbons such as heptane. This generates fire and explosion hazard.

Excerpt from ERG Guide 150 [Substances (Self-Reactive / Temperature Controlled)]:

Use water in large amounts, water spray. In case of fire: keep drums, etc., cool by spraying with water.

Fresh air, rest. Refer for medical attention.

Remove contaminated clothes. Rinse skin with plenty of water or shower.

First rinse with plenty of water for several minutes (remove contact lenses if easily possible), then refer for medical attention.

Induce vomiting (ONLY IN CONSCIOUS PERSONS!). Give a slurry of activated charcoal in water to drink. Refer for medical attention .

Consult an expert! Personal protection: filter respirator for organic gases and particulates adapted to the airborne concentration of the substance. Do NOT let this chemical enter the environment. Remove all ignition sources. Sweep spilled substance into covered containers. If appropriate, moisten first to prevent dusting.

Used as blowing agent (elastomers and plastics), catalyst (vinyl polymerizations), curing agent (unsaturated polyester resins), and fumigant (when heated); [HSDB]
