164 ETHYLENE
INHALATION: remove to fresh air; give artificial respiration if required. EYES: flush with water for
15 min. SKIN: flush with water. INGESTION: do NOT induce vomiting; give large amounts of water,
followed by milk or milk of magnesia; Toxicity by Inhalation (Threshold Limit Value): Data not
available; Short-Term Exposure Limits: Data not available; Toxicity by Ingestion: Grade 3; LD,, 50 to
500 mgkg; Late Toxicity: Data not available; Vqor (Gas) Irritant Characteristics: Vapors causes
severe irritation of eyes and throat and canister cause eye and lung injury. They cannot be tolerated
even at low concentration; Liquid or Solid Im’tant Characteristics: Severe skin irritant. Causes second-
and third-degree burns on short contact and is very injurious to the eyes; Odor 17rreshold Data not
available.
Fire Hazards - Flash Point (deg. F): 30 OC; FIammable Limits in Air (%): 2.9; Fire Extinguishing
Agents: Dry chemical; Fire Extinguishing Agents Not To Be Used: Water, foam; Special Hazards of
Combustion Products: Toxic hydrogen chloride and phosgene gases may be formed; Behavior in Fire:
Difficult to extinguish; re-ignition may occur. Contact with water applied to adjacent fire, produces
irritating hydrogen chloride fumes and flammable hydrogen gas; Ignition Temperature (deg. F): Data
not available; Electrical Hazard: Data not available; Burning Rate: 3.2 mmhin.
Chemical Reactivity - Reactivity with Water: Reacts vigorously, evolving hydrogen chloride
(hydrochloric acid); Reactivity with Common Materials: Reaction with surface moisture will generate
hydrogen chloride, which corrodes common metals; Stability During Transport: Stable; Neutralizing
Agents for Acids and Caustics: Flood with water, rinse with sodium bicarbonate or lime solution;
Polymrimion: Not pertinent; Inhibitor of Polymerization: Not pertinent.

Health Hazards Information - Recommended Personal Protective Equipment: Organic vapor canister
or air-supplied mask; Symptoms Following Exposure: Moderate concentration inhalation causes
drowsiness, dizziness, and unconsciousness. Overexposure causes headache, drowsiness, muscular
weakness; General Treatment for Exposure: Remove victim to fresh air, give artificial respiration and
oxygen if breathing has stopped, and call a physician; Toxicity by Inhalation: Simple asphyxiate; Short-
Term ,%posure Limits: Not pertinent; Toxicity by Ingestion: Not pertinent; Lute Toxicity: Not pertinent;
Vapor (Gas) Irritant Characteristics: Vapors are nonirritating to the eyes and throat; Liquid or Solid
Irritant Characteristics: No appreciable hazard. Practically harmless to the skin, but may cause
frostbite; Odor 17rreshold: Data not available.
Fire Hazards - Flash Point (deg. F): -213 (approx.) CC; Flammable Limits in Air (%): 2.75 - 28.6;
Fire Extinguishing Agents: Stop flow of gas if possible. Use carbon dioxide, dry chemical, water fog;
Fire Extinguishing Agents Not To Be Used: Not pertinent; aecial Hazards of Combustion Products:
Vapors are anesthetic; Behavior in Fire: Container may explode; Ignition Temperature (deg. F): 842;
Electrical Hazard: Class I, Group D; Burning Rate: 7.4 mm/min.
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;
