Health Hazards Iuformation - Recommended Personal Protective Equipment: Approved respirator;
rubber gloves; splash proof goggles; Symptoms Following Exposure: Inhalation causes dizziness and
headache. Ingestion causes bluish discoloration (cyanosis) of lips, ear lobes, and fingernail beds. Liquid
irritates eyes. Absorption through skin produces same symptoms as for ingestion; General Treatment
for Exposure: INHALATION: remove victim to fresh air and call a physician at once; administer
oxygen until physician arrives. INGESTION. give large amount of water; get medical attention at once.
EYES or SKIN: flush with plenty of water for at least 15 min.; if cyanosis is present, shower with soap
and warm water, with special attention to scalp and finger nails; remove any contaminated clothing;

Ertinguishing Agents: Dry chemical, foam, carbon dioxide; Fire Extinguishing Agents Not To Be Used:
Water may be ineffective; Special Hazardr of Combustion Products: Toxic vapors are generated when
heated; Behavior in Fire: Data not available; Ignition Temperature : Data not available; Electrical
Hazard: Data not available; Burning Rate: 3.65 mm/min.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Comn Materials: May
attack some forms of plastic; Stability Dluing Transporl: Stable; Neutralizing Agents for Acidr and

59.7, 2.50; Heat of Combustion: -3188, -1771, -74.15; Heat ofDecomposition: Not pertinent.
Health Hazards Information - Recommended Personal Protective Equipment: Self-contained
breathing apparatus; goggles; Symptoms Following Ecposure: Inhalation of vapor causes lung
congestion and pulmonary edema. Higher concentrations cause rapid narcosis and death. Contact with
liquid irritates eyes and burns skin; General Treatment for Exposure: INHALATION remove victim
to fresh air; give artificial respiration if needed. SKIN OR EYES: flush with water for at least 15 min.;
Toxicity by Inhalation (Threshold Limit Value): 15 ppm; Short-Tern Inhalation Limits: 20 ppm for 5
min.; Toxicity by Ingestion: Data not available; Late Toxicity: Data not available; Vapor (Gar) Irritant
Characteristics: Vapors are moderately irritating such that personnel will not usually tolerate moderate
or high concentrations; Liquid or Solid Im'tant Characteristics: Fairly severe skin irritant; may cause
pain and second-degree bums after a few minutes contact; Odor Threshold Data not available.
