382 TRIPROPYLENE GLYCOL

pertinent; Critical Pressure: Not pertinent; Specific Gravity: 0.846 at 20 "C (liquid); Vapor (Gas)
Density: 3.7; Ratio of Specij?c Heats of Vapor (Gas): (est.) 1.0683; Latent Heat of Vaporization: 126,
70, 2.9; Heat of Combustion: (est.) -10,300, -5,700, -240; Heat of Decomposition: Not pertinent.
Health Hazards Information - Recomnded Personal Protective Equipment: Acid-vapor-type
respiratory protection; rubber gloves; chemical worker's goggles; other protective equipment as
necessary to protect skin and eyes; Symptom Following Exposure: Inhalation of vapor irritates mucous
membranes. Contact of liquid with eyes or skin causes severe burns of mouth and stomach; General
Treafmentfor Exposure: Get medical attention all exposures to this compound. INHALATION: remove
victim from exposure; if breathing is difficult or stopped, give artificial respiration. EYES: flush with
water for 15 min. SKIN: flush with water. INGESTION: do NOT induce vomiting; give large amount
of water; Toxicity by Inhalation (Threshold Limit Value): Data not available; Short-Tern Exposure
Limits: Data not available; Toxicity by Ingestion: Grade 3, LD,, 0.5 to 5 g/kg; Late Toxicity: Data not
available; Vapor (Gas) Irritant Characteristics: Vapors cause severe irritation of eyes and throat and
can cause eye and lung injury. They cannot be tolerated even at low concentrations; Liquid or Solid
Irritant Characteristics: Severe skin irritant. Causes second- and third-degree burns on short contact
and is very injurious to the eyes; Odor i%reshold Data not available.
Fire Hazards - Flash Point (deg. F): 0 OC; FIammable Limits in Air (W): 1.8 &EL); Fire
Extinguishing Agents: Dry chemical; Fire Extinguishing Agents Not To Be Used: Water, foam; Special
Hazards of Combustion Products: Toxic and irritating hydrogen chloride and phosgene may form in
fires; Behavior in Fire: Difficult to extinguish; material easily re-ignites. Contact with water on
adjacent fires should be avoided as irritating and toxic hydrogen chloride gas will form; Ignition
Temperature (deg. F): 743; Electrical Hazard: No data; Burning Rate: 5.3 mm/min.
Chemical Reactivity - Reactivio with Water: Reacts vigorously forming hydrogen chloride
(hydrochloric acid); Reactivity with Common Materials: Reacts with surface moisture evolving
hydrogen chloride, which will corrode common metals and form flammable hydrogen gas; Stability
During Transport: Stable; Neutralking Agents for Acids and Caustics: Flush with water and rinse with
sodium bicarbonate or lime solution; Polymerization: Not pertinent; Inhibitor of Polymerization: Not
pertinent.
