44.05; Boiling Point at I atm.: 68.7, 20.4, 293.6; Freezing Point: -189, -123, 150; Critical
Temperature: 370, 188,461; Critical Pressure: 820,56,5.7; Specijic Gravity: 0.780 at 20 "C (liquid);
Vapor (Gas) Density: 1.5; Ratio of Specijic Heats of Vapor (Gas): 1.182; Latent Heat of Vaporization:
245, 136, 5.69; Heat of Combustion: -10600, -5890, -246.4; Heat of Decomposition: Not pertinent.
Health Hazards Information - Recommended Personal Protective Equipment: Rubber gloves, eye
goggles, and other equipment to prevent contact with the body. Organic canister or air pack as
required; Symptoms Following Exposure: Breathing vapors will be irritating and may cause nausea,
vomiting, headache, and unconsciousness. Contact with eyes may cause burns. Skin contact from
clothing wet with the chemical causes burns or severe irritation; General Treatment for Exposure:
INHALATION: remove victim to fresh air; if breathing has stopped, give artificial respiration; if
breathing is difficult, give oxygen; call a physician at once. SKIN: wash with soap and water. EYES:
flush with water; Toxicity by Inhalation (Threshold Limit Value): 100 pprn; Short-Tenn Exposure
Limits: 50 ppm for 60 min.; Toxicity by Ingestion: LD, 0.5 to 5 glkg (cat); Late Toxicity: No data
found; Vapor (Gas) Irritant Chamcteristics: Vapor is moderately irritating such that workers will not
usually tolerate moderate to high concentrations; Liquid or Solid Irritant Characteristics: Minimum
hazard. If spilled on clothing and allowed to remain, may cause smarting and reddening of the skin;
Odor Threshold 0.21 pprn.
Fire Hazards - Flash Point (deg. F): -36 CC; -59 OC; Flammable Limits in Air (56): 4 - 60; 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: Produces irritating
vapors when heated; Behavior in Fire: Vapors are heavier than air and may travel to a considerable
distance for a source of ignition and flash back; Ignition Temperature (deg. F): 365; Electrical Hazard
Class 1, Group C; Burning Rate: 3.3 dmin.
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: May occur. Avoid contact with heat, dust, strong oxidizing and reducing agents, strong
acids and bases; Inhibitor of Polyrnerimtion: None.

ACETIC ACID
Chemical Designations - Synonyms: Ethanoic Acid, Glacial Acetic Acid, Vinegar acid; Chemical

Health Hazards Information - Recommended Personal Protective Equipment: Protective clothing
should be worn when skin contact can occur. Respiratory protection is necessary when exposed to
vapor. Complete eye protection is recommended; @mptoms Following Exposure: Breathing of vapors
