• Acrylonitrile is highly flammable and gives off toxic fumes in a fire.
• A closed system, ventilation, explosion-proof electrical equipment and lighting can be used to prevent explosion.

In case of fire, responders should use powder, alcohol-resistant foam, water spray, or carbon dioxide. Acrylonitrile is highly flammable. It gives off irritating or toxic fumes or gases in a fire. To prevent fire, no open flames, sparks, smoking or contact with strong oxidants or strong bases should be allowed.

In case of explosion and subsequent fire, it is necessary to keep drums etc., cool by spraying them with water. The vapor/air mixtures of acrylonitrile are explosive. The risk of fire and explosion occurs upon polymerization on contact with strong bases and strong oxidants. A closed system, ventilation, explosion-proof electrical equipment and lighting can be used to prevent explosion.

Acrylonitrile should be stored in unbreakable, fireproof containers away from strong oxidants, strong bases, food, and light. AN should be ventilated along the floor and stored only if stabilized.

If acrylonitrile should spill, personnel should evacuate the danger area and consult an expert. The area should be ventilated, if possible, and leaking liquid collected in covered containers. The remaining liquid should be absorbed in sand or inert absorbent and removed to a safe place. It is important not to wash this chemical into the sewer or let it enter the environment.
