Health Hazards Information - Recommended Personal Protective Equipment: Air pack or organic
canister mask; chemical goggles; Symptoms Following Exposure: Contact with eyes is extremely
irritating and may cause burns. Breathing vapors will be irritating to the nose and throat. In high
concentrations, may cause nausea, dizziness, headache, and stupor; General Trearment for Exposure:
INHALATION: if victim is overcome by vapors, remove him from exposure immediately; call a
physician; if breathing is irregular or has stopped, start resuscitation; administer oxygen. EYES: flush
with water for at least 15 minutes; Toxicity by Inhalation (Threshold Limit Value): 100 ppm; Short-
Term Inhalation Limits: 200 ppm for 60 min.; Toxicity by Ingestion: Grade 2, LD,, 0.5 to 5 glkg (rat);
Late Toxicity: Data not available; Vapor (Gas) Im'tant Characteristics: Vapors causes a slight smarting
of the eyes or respiratory system if present in high concentrations. The effect is temporary; Liquid or
Solid Irritant Characteristics: No appreciable hazard. Practically harmless to the skin; Odor Threshold:

Health Hazards Information -Recommended Personal Protective Equipment: Self-contained breathing
apparatus; butyl rubber gloves; chemical face shield; butyl rubber apron; Symptoms Following
Exposure: Inhalation causes severe coughing and chest pain due to irritation of air passages; can cause
lung edema. Compound is sympathomimetic and is also a cardiac depressant and convulsant; ingestion
causes nausea and profuse salivation. Contact with skin causes severe irritation; General Treatment for
Exposure: INHALATION: remove victim to fresh air; if he is not breathing, give artificial respiration;
if breathing is difficult, give oxygen; call a physician. INGESTION: give large amount of water
followed by dilute vinegar or lemon juice; keep patient warm. EYES: flush with water for 15 min.
SKIN: flush with water; Toxicity by Inhalation (ThresholdLimit Value): 5 ppm; Short-Term Inhalatian
Limits: Data not available; Toxicity by Ingestion: Grade 3; oral LD50 = 120 mg/kg (rabbit), 250 mglkg
(rat); Late Toxicity: Data not available; Vapor (Gas) Irritant Characteristics: Vapors are moderately
irritating such that personnel will not usually tolerate moderate or high concentrations; Liquid or Solid
Im'tant Characteristics: Severe skin irritant. Causes second- and third-degree burns on short contact
and is very injurious to the eyes; Odor Threshold Data not available.
Fire Hazards - Flash Point (deg. F): 15 CC; Flammable Limits in Air (%): 3.4 - 9; Fire Extinguishing
Agents: Dry chemical, alcohol foam, or carbon dioxide; Fire Entinguishing Agents Not To Be Used:
Water may be ineffective; aecial Hazards of Combustion Products: Toxic oxides of nitrogen form in
