Sodium azide poisoning in five laboratory technicians

Abstract
Five laboratory technicians accidentally ingested sodium azide, 20-80 mg, in tea made from distilled water kept in a laboratory. Four had short-lived symptoms of dizziness, pounding heart and faintness, while another developed myocardial ischemia. He had further episodes of chest pains necessitating admission to a hospital. These later symptoms were thought to be psychogenic in origin.
