Most important symptoms/effects, acute and delayed
Excerpt from ERG Guide 150 [Substances (Self-Reactive / Temperature Controlled)]: Inhalation or contact with vapors, substance or decomposition products may cause severe injury or death. May produce irritating, toxic and/or corrosive gases. Runoff from fire control may cause pollution. (ERG, 2016)
Indication of immediate medical attention and special treatment needed, if necessary
no data available
SECTION 5: Firefighting measures
Suitable extinguishing media
Excerpt from ERG Guide 150 [Substances (Self-Reactive / Temperature Controlled)]: The temperature of the substance must be maintained at or below the "Control Temperature" at all times. SMALL FIRE: Dry chemical, CO2, water spray or regular foam. LARGE FIRE: Flood fire area with water from a distance. Move containers from fire area if you can do it without risk. FIRE INVOLVING TANKS OR CAR/TRAILER LOADS: BEWARE OF POSSIBLE CONTAINER EXPLOSION. Fight fire from maximum distance or use unmanned hose holders or monitor nozzles. Cool containers with flooding quantities of water until well after fire is out. Withdraw immediately in case of rising sound from venting safety devices or discoloration of tank. ALWAYS stay away from tanks engulfed in fire. (ERG, 2016)
Specific hazards arising from the chemical
Excerpt from ERG Guide 150 [Substances (Self-Reactive / Temperature Controlled)]: Self-decomposition, self-polymerization, 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. Above a given "Control Temperature" they decompose or polymerize violently and may catch fire. May be ignited by heat, sparks or flames. Those substances designated with a (P) may polymerize explosively when heated or involved in a fire. Some may decompose 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)
Special protective actions for fire-fighters
Use water in large amounts, water spray. In case of fire: keep drums, etc., cool by spraying with water.
SECTION 6: Accidental release measures
Personal precautions, protective equipment and emergency procedures
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.
Environmental precautions

SECTION 10: Stability and reactivity
Reactivity
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.
Chemical stability
no data available
Possibility of hazardous reactions
If dry, it can be charged electrostatically by swirling, pneumatic transport, pouring, etc.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.
