Extinguishing Agents: Not pertinent; Fire Extinguishing Agents Not to be Used: Do not use water on
adjacent fire; Special Hazards of Combustion Products: Irritating hydrogen bromide and phosphoric
acid vapors may form in fire; Behavior in Fire: Acids formed by reaction with water will attack metals
and generate flammable hydrogen gas, which may form explosive mixtures in enclosed spaces; Ignition
Temperature : Not pertinent; Electrical Hazard: Not pertinent; Burning Rate: Not pertinent.
Chemical Reactivity - Reactivity with Water: Reacts violently with water, evolving hydrogen bromide,
an irritating and corrosive gas apparent as white fumes; Reactivity with Common Materials: In the
presence of moisture, highly corrosive to most metals except lead and nickel; Stability During
Transport: Unstable if heated; Neutralizing Agentsfor Acids and Caustics: Flush with water, rinse with
dilute aqueous sodium bicarbonate or soda ash; Polymerization: Not pertinent; Inhibitor of
Polymerization: Not pertinent.

Health Hazards Information - Recommended Personal Protective Equipment: Chemical safety
goggles; plastic face shield; self-contained or air-line respirator; safety hat; rubber gloves and clothing;
Symptoms Following Exposure: Vapors cause severe irritation of eyes and respiratory tract. Liquid
burns eyes and skin; General Treamnt for Exposure: CAUTION: persons doing treannent should
protect themselves against exposure. INHALATION: remove victim from contaminated area at once;
if breathing has stopped, start artificial respiration; call a doctor. INGESTION: if victim is conscious,
give large quantities of water; do NOT induce vomiting. SKIN: remove contaminated clothii and
flood exposed skin surfaces with water. EYES: retract eyelids and wash with water for at least 15 min.;
call a doctor; Toxicity by Inhalation (Threshold Limit Value): 0.5 ppm; Short-Term Inhalation Limits:
Data not available; Toxicity by Ingestion: Grade 2, oral rat LD,,550 mglkg; Late Toxicity: None; Vapor
(Gas) Irritant Characteristics: Vapor cause severe irritation of eyes and throat and can cause eye and
lung injury. They camt 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; Flammable Limits in Air (%): Not flammable; Fire
Extinguishing Agents: Sand, carbon dioxide and dry chemicals on adjacent fires; Fire Extinguishing
Agents Not to be Used: Water; Special Hazards of Combustion Products: Not pertinent; Behavior in
Fire: Generates toxic, irritating gases; Ignition Temperature : Not flammable; Electrical Hazard Not
pertinent; Burning Rate: Not flammable.
Chemical Reactivity - Reactivity with Water: Reacts violently and may cause flashes of fire.
Hydrochloric acid fumes are formed in the reaction; Reactivity with Comn Materials: Corrodes most
common construction materials. Reacts with water to form hydrochloric acid, which reacts with most
metals to form flammable hydrogen gas; Stability During Transport: Stable; Neutralizing Agents for
Acids and Caurtics: Flush with water; neutralize acids formed with lime or soda ash; Polymerizm.on:
Not pertinent; Inhibitor of Polymerization: Not pertinent.
