Sources of ignition, such as smoking and open flames, areprohibited where 2,2-Azobisisobutyronitrile is used, handled, or stored in amanner that could create a potential fire or explosion hazard.

Safety Profile Of 2,2-Azobisisobutyronitrile:
Poison by intraperitoneal route.
Moderately toxic by ingestion.
2,2-Azobisisobutyronitrile violent exothermic decomposition when heated.

Solution in acetone may decompose explosively.
Explodes when heated with heptane.
When heated to decomposition it emits toxic fumes of NO, and CN-.

2,2-Azobisisobutyronitrile is safer to use than benzoyl peroxide (another radical initiator) because the risk of explosion is far less.
However, 2,2-Azobisisobutyronitrile is still considered as an explosive compound, decomposing above 65 °C.

A respirator dust mask, protective gloves and safety glasses are recommended.
Pyrolysis of 2,2-Azobisisobutyronitrile without a trap for the formed 2-cyanopropyl radicals results in the formation of tetramethyl succinonitrile, which is highly toxic.
