Health Hazards Information - Recommended Personal Protective Equipment: Rubber gloves, shoes,
and clothing, goggles and face shield, acid-type canister mask or air-line mask; Symptoms Following
Exposure: Inhalation of fumes causes severe irritation of nose and throat. Contact of liquid with eyes
or skin causes very severe burns. Ingestion causes very severe burns of mouth and stomach; General
Treatment for Exposure: Get medical attention quickly following all exposures to this compound.
INHALATION: remove victim to fresh air; if he is unconscious, give artificial respiration. EYES:
flush with water until medical help arrives. SKIN: flush with water until medical help arrives; soak
burned area in strong Epsom salt solution; pay particular attention to area around fingernails.
INGESTION: give large amounts of water; Toxicity by Inhalation (Threshold Limit Value): Data not
available; Wwrt-Tenn Inhalation Limits: Data not available; Toxicity by Ingestion: Data not available;
Late Toxicity: Data not available; Vapor (Gas) Im'tant Characteristics: Vapors cause severe irritation
of eyes and throat and can cause eye and lung injury. They cannot be tolerated even at low
concentrations; Liquid or Solid Irritant Characteristics: Severe skin irritant. Causes second- and third-
degree bums on short contact and very injurious to the eyes; Odor 27zreshold Data not available.
