Health Hazards Information -Recommended Personal Protective Equipment: Self-contained breathing
apparatus; goggles; rubber gloves; Symptoms Following Exposure: Inhalation, ingestion, or skincontact
causes weakness, headache, confusion, nausea, vomiting; acute cyanide poisoning may result. Contact
with eyes causes irritation; General Treamzent for Exposure: Get medical attention following all
overexposures to this chemical. Watch for symptoms of cyanide poisoning. INHALATION: move
patient to fresh air; apply artificial respiration if breathing stops. INGESTION break an amyl nitrite
pearl in a cloth and hold lightly under patient's nose for 15 sec.; if he is conscious, induce vomiting
and repeat until vomit is clear; repeat inhalation of amyl nitrite 5 times at 15-sec. intervals. EYES:
