Gas: colorless. Liquid: greenish-yellow; Odor: Acrid; strong, pungent, sweetish; sweet and irritating.
Physical and Chemical Properties - Physical State at 15 rand I atm. : Gas; Molecular Weight: 92.5;
Boiling Point at I abn.: 53, 11.6, 284.8; Freezing Point: -105, -76.1, 197.1; Critical Temperature:
307, 153,426; Critical Pressure: 837,56.9,5.77; Specijic Gravity: 1.85 at 11 “C (liquid); Vqor (Gas)
Density: 3.2; Ratio of SpeciJc Heats of Vapor (Gas): 1.2832; L.utent Heat of Vaporization: 128,71.2,
2.98; Heat of Combustion: Not pertinent; Heat of Decomposition: Not pertinent.
Health Hazards Information - Recommended Personal Protective Equipment: Neoprene gloves and
protective clothing made of glass fiber and Teflon, including full hood; self-contained breathmg
apparatus with full face mask; Symptoms Following Exposure: Inhalation causes extreme irritation of
respiratory tract; pulmonary edema may result. Vapors are very irritating to eyes and skin; liquid
causes severe burns; General Treament for Exposure: Call physician at once after any exposure to this
compound. INHALATION: remove victim to fresh air and keep him quiet; give artificial respiration
if breathing has stopped; give oxygen; enforce rest for 24 hours. EYES: flush with water for at least
15 min.; get medical attention, but do not interrupt flushing for at least 10 min. SKIN: flush with
water, then with 2-376 aqueous ammonia, then again with water; apply ice-cold pack of saturated
Epsom salt or 70% ethyl alcohol; Toxicity by Inhalation (Threshold Limit Value): 0.1 ppm (ceiling
point); Short-Tern Exposure Limits: 0.1 ppm for 5 min. ; Toxicity by Ingestion: Grade 4; LD,, < 50
mg/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 Threshold Data not available.
Fire Hazards - Flash Point: Not flammable, but can cause fire when mixed or in contact with some
materials; Flammable Limits in Air (9%): Not pertinent; Fire Extinguishing Agents: Dry chemical; Fire
Extinguishing Agents Not To Be Used Do not use water on adjacent fires unless well protected against
hydrogen fluoride gas; Special Hazards of Combustion Products: Fumes are highly toxic and irritating;
Behavior in Fire: Can greatly increase the intensity of fires. Containers or vessels may explode;
Ignition Temperature: Not pertinent; Electrical Hazard Not pertinent; Burning Rate: Not pertinent.
Chemical Reactivity - Reactivity with Water: Reacts explosively with water, producing hydrogen
fluoride (hydrofluoric acid) and chlorine; Reactivity with Common Materials: Causes ignition of all
combustible materials and some inerts such as sand and concrete. The chemical is very similar to
fluorine gas; Stability During Tramport: Stable; Neutralizing Agents forAcids and Caustics: Flood with
water; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
