minor injury; repeated contact with skin will remove natural oils and may cause dermatitis; General
Trement for Exposure: INHALATION: remove victim to fresh air and obtain medical attention
immediately; keep him warm and at rest, and give artificial respiratory if breathing stops; maintain an
open airway. EYES: flush with water for 15 min. SKIN: flush with water. INGESTION: do NOT
induce vomiting; get medical attention; Toxicity by Inhalation (Threshold Limit Value): 250 ppm
(tentative); Short-Tern Inhalation Limits: Grade 1; oral LD, = 8,470 mglkg (rat); Toxicity by
Ingestion: Data not available; Lute Toxicity: Data not available; Vapor (Gas) Irritant 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: Minimum hazard. If spilled on clothing
and allowed to remain, may cause smarting and reddening of skin; Odor Threshold Data not available.
Fire Hazards - Flash Point (deg. F): -15 OC, -18 CC; Flammable Limits in Air (Z): 1.4 - 7.9; Fire
fitinguishing Agents: Dry chemical, alcohol foam, or carbon dioxide; Fire Extinguishing Agents Not
To Be Used: Water may be ineffective; Special Hazards of Combustion Products: Not pertinent;
Behavior in Fire: Vapor is heavier than air and may travel to a source of ignition and flash back.
Containers may explode; Ignition Temperature (deg. F): 830; Electrical Hazard: No data; Burning
Rate: 5.0 mmlmin.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: No
reactions; stability During Transport: Unstable peroxides may form if the product contacts air for long
time periods. These may explode spontaneously or when heated; Neutralizing Agents for Acids and
Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
