First Aid Measures

Ingestion

Seek medical attention. If individual is drowsy or unconscious, do not give anything by mouth; place individual on the left side with the head down. Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting. If possible, do not leave individual unattended.

Inhalation

If symptoms develop, immediately move individual away from exposure and into fresh air. Seek immediate medical attention; keep person warm and quiet. If person is not breathing, begin artificial respiration. If breathing is difficult, administer oxygen. A cyanide antidote kit must be available at all times. Immediate first aid, including administration of oxygen and amyl nitrite, may be given by a trained layman. Medical treatment involves intravenous injection and must be administered by qualified medical personnel. Speed of treatment is very important. First aid given promptly is often the only treatment needed.
