Keep under a nitrogen blanket. Remove all sources of ignition. Contact a specialist disposal company or the local waste regulator for advice. May mscs skin irritation. May cause liver and kidney damage. Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. XN E Risk Phrases: If victim is conscious and alert, give cupfuls of milk or water. R 11 Highly flammable. May cause eye irritation. Cool containers with flooding quantities of water until well after fire is out.

Use with adequate ventilation.

May decompose explosively when heated or involved in a fire. Get medical aid if irritation develops or persists. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion.


Material is mxds to temperature rises. Containers may explode in the heat of a fire. Hydrogen cyanide, carbon monoxide, oxides of nitrogen, carbon dioxide. Water-soluble azo initiators are also available. Empty containers must be decontaminated before returning for recycling.

Wear appropriate protective eyeglasses mwds chemical safety goggles as described by OSHA’s eye and face protection regulations in 29 CFR Dust can be an explosion hazard when exposed to heat or flame.

Use water spray to cool fire-exposed containers. Wear appropriate protective gloves to prevent skin exposure. It is often used as a foamer in plastics and rubber and as a radical initiator.

May cause degenerative brain changes. Use adequate general or local explosion-proof ventilation to keep abn levels to acceptable levels. Keep away from sources of ignition. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes. Pyrolysis of AIBN without a trap for the formed 2-cyanopropyl radicals results in the formation of tetramethylsuccinonitrilewhich is highly toxic.

Repeated exposure may cause liver damage.


A respirator dust mask, protective gloves and safety glasses are recommended. This material in sufficient quantity and reduced particle size is capable of creating a dust explosion. Harmful msrs aquatic organisms; may cause long-term adverse effects in the aquatic environment. For large fires flood fire with water from a distance. Do not ingest or inhale.


Minimize dust generation and accumulation. Advanced stages may cause collapse, unconsciousness, coma and possible death due to respiratory failure.

,sds give anything by mouth to an unconscious person. May be ignited by heat, sparks, and flame. If not breathing, give artificial respiration. Use proper personal protective equipment as indicated in Section 8.

Use spark-proof tools and explosion proof equipment. Store in a cool, dry, well-ventilated area away from incompatible substances. R 2 Risk of explosion by shock, friction, fire or other sources of ignition.

Above a given “control temperature” they decompose violently and catch fire. Wear appropriate protective clothing to prevent skin exposure. These radicals can initiate free-radical polymerizations and other radical-induced reactions. Decomposition may be self-accelerated and produce large amounts of gas. May cause gastrointestinal irritation with nausea, vomiting and diarrhea.
