be accompanied by complaints of photophobia and pain in the eyeball; pain may not begin until 6 hours
after exposure. Liquid may cause first- and second-degree burns of the skin, with blister formation;
underlying part will become swollen and painful, and local muscle spasms may occur; General
Treatment for Exposure: INHALATION: remove victim from contaminated area and administer
oxygen; get medical attention immediately. SKIN: remove liquid with soap and water. EYES: flush
with continuous stream of water for 15 min.; Toxicity by Inhalation (ThresholdLimit Value): 2 ppm;
Short-Term Exposure Limits: 5 ppm for 30 min; Toxicity by Ingestion: Grade 3; LD,, 50 to 500 mg/kg
(mouse, rat); Late Toxicity: Data not available; Vapor (Gas) Irritant Characteristics: Vapor is
moderately irritating such that personnel will not usually tolerate moderate or high vapor concentration;
Liquid or Solid Irritant Characteristics: Causes smarting of the skin and first-degree burns on short
exposure; may cause secondary burns on a long exposure; Odor Threshold: 0.78 ppm.
Fire Hazards - Flash Point (deg. F): 72 CC; 90 OC; Flammable Limits in Air (96): 2.5 - 18; Fire
Extinguishing Agents: Dry chemical, alcohol foam, carbon dioxide; Fire Extinguishing Agents Not To
Be Used Water may be ineffective; special Hazards of Combustion Products: Toxic vapor is generated
when heated; Behavior in Fire: Vapor heavier than air and may travel a considerable distance to a
source of ignition and flash back; Ignition Temperature (deg. F) 2329; Electrical Hazard: Not pertinent;
Burning Rate: 2.7 mdmin.
Chemical Reactivity - Reactivity with Water: No reaction; Reactivity with Comn Materials: No
reaction; Stability During Transport: Stable at ordinary temperatures and pressures; Neutralizing Agents
for Acids and Caustics: Not pertinent; Polymerizah’on: Not pertinent; Inhibitor of Polymerization: Not
pertinent.

Health Hazards Information - Recommended Personal Protective Equipment: Vapor-proof protective
goggles and face shield; plastic or rubber gloves, shoes and clothing; gas mask or self-contained
breathq apparatus; Symptoms Following Exposure: Vapor irritates eyes and respiratory tract. Contact
with liquid causes eye and skin irritation, and ingestion irritates mouth and stomach; General Treatment
for Exposure: INHALATION remove from exposure; support respiration if necessary; call physician.
EYES: if irritated by either vapor or liquid, flush with water for at least 15 min. SKIN: wash with
large amounts of water for at least 15 min. INGESTION: do NOT induce vomiting; give water; call
physician; Toxicity by Inhalation (Threshold Limit Value) : Data not available; Short-Tern Exposure
Limits: Data not available; Toxicity by Ingestion: Grade 3; LD,, 50 to 500 mg/kg; Late Toxicity: Data
not available; Vapor (Gas) Im*tant Characteristics: Vapors are moderately irritating such that personnel
will not usually tolerate moderate or high vapor concentrations; Liquid or Solid Zm-tm Characteristics:
Fairly severe skin irritant. May cause pain and second-degree burns after a few minutes’ contact; Odor
Threshold: 1.4 ppm.
