Health Hazards Information - Recommended Personal Protective Equipment: Safety goggles; gloves;
adequate ventilation; provisions for flushing eyes or skin with water; Symptoms Following Exposure:
Inhalation results in primary irritation of the respiratory tract; symptoms of lung damage may be
delayed. Contact with liquid produces primary irritation of eyes and severe skin damage; delayed
blistering of the skin often occurs; General Treatment for Exposure: INHALATION: Remove the
victim from the contaminated area. If breathing has stopped, give artificial respiration. If breathing is
difficult, give oxygen. Watch victim carefully for any signs of delayed lung damage. EYES: Flush with
water for at least 15 min. and seek medical attention. SKIN: Flush with water and treat chemical burns
as needed; Toxicity by Inhalation (llreshold Limit Value): No data; Short-Term Exposure Limits: No
data; Toxicity by Ingestion: Oral rat LD50 3,310 mg/kg (acetic acid). Note that this chemical
decomposes violently in water, forming bromic acid and acetic acid; Late Toxicity: No data; Vapor
(Gas) Irritant Characteristics: No data; Liquid or Solid Irritant Characteristics: No data; Odor
i%reshold 5.0 X lo4 ppm.
Fire Hazards - Flash Point: Data not available; Flammable Limits in Air (%): Data not available; Fire
Extinguishing Agents: Carbon dioxide; Fire Extinguishing Agents Not To Be Used Water; slpecial
Hazards of Combustion Products: Toxic and irritating hydrogen bromide fumes may form in fires;
Behavior in Fire: Do not apply water to adjacent fires. Reacts with water to produce toxic and irritating
gases; Ignition Temperature: Data not available; Electrical Hazard Data not available: Bunring Rate:
Data not available.
Chemical Reactivity - Reactivity with Water: Reacts violently, forming corrosive and toxic fumes of
hydrogen bromide; Reactivity with Common Materials: Attacks and corrodes wood and most metals in
the presence of moisture. Flammable hydrogen gas may collect in enclosed spaces; Stability During
Transport: Stable if protected from moisture; Neutralizing Agents for Acids and Caustics: Flood with
water, rinse with dilute sodium bicarbonate or soda ash solution; Polymerization: Not pertinent;
Inhibitor of Polymerization: Not pertinent.
