Health Hazards Information - Recommended Personal Protective Equipment: Fresh air mask; rubber
gloves; goggles; safety shower and eye bath, Symptoms Following Exposure: No significant irritation
from brief exposure of skin; prolonged or repeated exposure may cause a rash or burn and absorption
of toxic amounts leading to serious injury of liver and kidney. Chemical has poor warning properties;
illness may be delayed. Moderately irritating to eyes; overexposure may cause corneal injury; General
Treatment for Exposure: INHALATION: promptly remove victim to fresh air, keep him quiet and
warm, and call physician; start artificial respiration if breathing stops. INGESTION: if large amounts
are swallowed, quickly induce vomiting and get medical attention; no specific antidote known. SKIN
AND EYES: flush with plenty of water for 15 min.; remove contaminated clothing and wash before
reuse; get medical attention for eyes and if ill effects occur from skin contact; Toxicity by Inhalation
(Threshold Limit Value): 100 ppm; Short-Term Exposure Limits: 100 ppm for 60 min.; Toxicity by
Ingestion: Grade 2; LD,, 0.5 to 5 glkg (guinea pig: 3.90 glkg); Late Toxicity: Causes cancer in rats;
Vapor (Gas) Zm’tm Characteristics: Vapors cause a slight of the eyes or respiratory system if present
in high concentrations. The effect is temporary; Liquid or Solid Zm’tant Characteristics: Minimum
hazard. If spilled on clothing and allowed to remain, may cause smarting and reddening of the skin;
Odor Threshold 620 mg/m3.
Fire Hazards - Flash Point (deg. F): 54 CC; 74 OC; Flammuble Limits in Air (%): 1.9 - 22.5 by vol;
Fire Extinguishing Agents: Alcohol foam, carbon dioxide, dry chemical; Fire Extinguishing Agents Not
to be Used: Not pertinent; Special Hazards of Combustion Products: Toxic vapors are generated when
heated; Behavior in Fire: Vapor is heavier than air and may travel to a source of ignition and flash
back; Ignition Temperature (deg. F): 356; Electrical Hard: Not pertinent; Burning Rate: Data not
available.
Chemical Reactivity - Reactivity with Water : No reaction; Reactivity with Comn Materials: No
reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent;
Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
