Health Hazards Information -Recommended Personal Protective Equipment: Rubber gloves; chemical
resistant splash-proof goggles; rubber boots; chemical protective clothing for splash protection,
chemical cartridge type respirator or other suitable protection against vapor must be worn when
working in poorly ventilated areas or where overexposure by inhalation could occur.; Symptoms
Following Exposure: Personnel can be overexposed to this chemical by ingestion, absorption through
the skin, or inhalation. The earliest symptoms of cyano-compound intoxication may be weakness,
headaches, confusion, and occasionally nausea and vomiting. The respiratory rate and depth will usually
be increased at the beginning and at later stages become slow and gasping. Blood pressure is usually
normal, especially in mild or moderately severe cases, although the pulse rate is usually more rapid
than normal.; General Treatment for Exposure: INHALATION: Remove patient to fresh air; seek
immediate medical attention. INGESTION: Call physician immediately. Until doctor arrives, take the
following steps: a) Provide for inhalation by amyl nitrate vapor from ampules crushed in a handkerchief
and held to nose of victim. b) Induce vomiting unless patient is unconscious. (Gastric lavage should be
employed by, or under the supervision of a physician). c) Keep patient warm and quiet until medical
attention arrives. EYES: Immediately flush with large volumes of fresh water for ate least 15 minutes.
SKIN: Wash thoroughly at once, without scrubbing, with large amounts of soap and water. OTHER:
Exposed personnel should be checked periodically for chronic toxic effects.; Toxicity by Inhalation
(Threshold Limit Value): No data; Short-Term Exposure Limits: No data; Toxicity by Ingestion: LD,,
