Avoid sources of extreme heat or ignition including sparks or fire. Isobutyronitrile will liberate toxic nitrogen oxide fumes when heated to decomposition. Heart palpitation may occur within minutes after exposure. High doses can stop breathing. Vital signs should be monitored closely.
Caution is advised.
Lung hemorrhage and pulmonary edema may occur. Isobutyronitrile is irritating to the skin and mucous membranes. Acute exposure to isobutyronitrile may require decontamination and life support for the victims. All exposed persons should be transported to a health care facility as quickly as possible. Emergency personnel should wear protective clothing appropriate to the type and degree of contamination.
