Health Hazards Information - Recommended Personal Protective Equipment: Organic vapor canister
or air-supplied respirator; synthetic rubber gloves; chemical safety goggles or face splash shield;
Symptoms Following fiposure: INHALATION: vapor irritating to eyes and mucous membranes; acts
as an anesthetic in very high concentrations. INGESTION: low order of toxicity but very irritating to
the mucous membranes. SKIN: prolonged excessive contact causes defatting of the skin, possibly
leading to dermatitis; Generd Treatment for Exposure: INHALATION: if victim is overcome, remove
to fresh air and call a physician; administer artificial respiration if breathing is irregular or stopped.
INGESTION: if victim has swallowed large amounts and is conscious and not having convulsions,
induce vomiting and seek medical help immediately. SKIN: wash with clean running water. EYES:
flush with water immediately for at least 15 min. and .consult a physician; Toxicity by Inhalation
(Threshold Limit Value): 1000 ppm; Short-Tern Exposure Limits: 1000 ppm for 30 minutes; Toxicity
by Ingestion: LD,, 5 to 15 glkg (dog); Late Toxicity: Not pertinent; Vapor (Gas) Irritant
Characteristics: If present in high concentrations, vapors cause moderate irritation of the eyes or
respiratory system. Effects are temporary; Liquid or Solid Irritant Characteristics: No appreciable
hazard. Practically harmless to the skin because it is very volatile and evaporates quickly from the skin;
Odor E3reshold: 100 ppm.
Fire Hazards - Flash Point (deg. F): 4 OC, 0 CC; Flammable Limits in Air (96): 2.6 - 12.8; Fire
Extinguishing Agents: Alcohol foam, dry chemical, carbon dioxide; Fire Extinguishing Agents Not To
Be Used Water in straight hose streams will scatter fire and is not recommended; Special Hazards of
Combustion Products: Not pertinent; Behavior in Fire: Not pertinent; Ignition Temperature (deg. F):
869; Elecm‘cal Hazard Class I, Group D; Buming Rate: 3.9 mmlmin.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Common Materials: No
reaction; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent;
Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
