Azo compounds Polymer chemistry Aibm for organic chemistry Radical initiators. Wash hands before eating. Related azo compounds behave similarly, e. May cause gastrointestinal irritation with nausea, vomiting and diarrhea. AIBN is safer to use than benzoyl peroxide another radical initiator because the risk of explosion is far less. Views Read Edit View history. XN E Risk Phrases: Wear appropriate protective clothing to prevent skin exposure.

May be ignited by heat, sparks, and flame.


Substance is shock sensitive and thermally unstable. Use proper personal protective equipment as indicated in Section msrs. Get medical aid if irritation develops or persists. Wash thoroughly after handling.

Use water spray to cool fire-exposed containers. Vapors or dust may form explosive mixture with air. If victim is conscious and alert, give cupfuls of milk or water. Effects may be delayed.


May decompose explosively when heated or involved in a fire. For small fires, use dry chemical, carbon dioxide, water spray or regular foam.

Empty containers must be decontaminated before returning for recycling. May cause central nervous system depression, characterized by excitement, followed by headache, dizziness, drowsiness, and nausea. Ainb stages may cause collapse, unconsciousness, coma and possible death due to respiratory failure.

Use spark-proof tools and explosion proof equipment.

Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower. Use with adequate ventilation.

Never give anything by mouth to an unconscious person. These radicals can initiate free-radical polymerizations and other radical-induced reactions. Use adequate general or local explosion-proof ventilation to keep airborne levels to acceptable levels. Self-accelerating decomposition may occur if the temperature is not maintained. R 2 Risk of explosion by shock, friction, fire or other sources of ignition. Keep container tightly closed. Do not ingest or msd. May cause degenerative brain changes.

Keep away from sources of ignition. If breathing is difficult, give oxygen. Another example of a radical reaction that can be initiated by AIBN is the anti-Markovnikov hydrohalogenation of alkenes.

May cause skin irritation. Personal Protective Equipment Eyes: Has not been reported. Dust can be an explosion hazard when exposed to heat or flame.

Repeated exposure may cause liver damage. Store in a mxds, dry, well-ventilated area away from incompatible substances. Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA’s eye and face protection regulations in 29 CFR Get medical aid immediately.

In other projects Wikimedia Commons. Store in a tightly closed container.


This material in sufficient quantity and reduced particle size is capable of creating a dust explosion. S 61 Avoid release to the environment. Avoid contact with heat, sparks and flame.

Cool containers with flooding quantities of water until well after fire is out.
