              Health Hazards Information - Recommended Personal Protective Equipment: Safety goggles and face
              shield; acid-type canister gas mask; rubber gloves; protective clothing; Symptoms Following Exposure:
              Inhalation causes irritation of  nose and throat.  Contact of  liquid with eyes or skin causes severe
              irritation. Ingestion causes weakness and severe irritation of mouth and stomach. Overdose can cause
              arsenic poisoning, but symptoms are delayed; General Treatmentfor Exposure: Get medical attention
              after all exposures to the compound. Be alert fro arsenic poisoning symptoms. INHALATION remove
              to fresh air; give artificial respiration if needed. EYES: flush with water for at least 15 min. SKIN:
              flush with water. INGESTION: give large amounts of water, then induce vomiting; give lime water,
              milk, or raw egg; give a cathartic; Toxicity by Inhalation (ThreshoMLimit Value): 0.5 mg/m3 (as
              arsenic);  Short-Tern Exposure Limits: Data not available; Toxicity by Ingestion: Grade 3; oral rat LD50
              138  mg/kg; fatal human dose 70-180 mg, depending on weight; Late Toxicity: Arsenic compounds may
              be carcinogenic; Vapor (Gas) Im’tant Characteristics: Data not  available; Liquid  or solid Irritant
              Characteristics: Data not available; Odor lkreshold  Data not available.
              Fire Hazards - Flash Point: Not  flammable; Flammable Limits in Air (96):  Not  flammable; Fire
              Extinguishing Agents: Not pertinent; Fire Extinguishing Agents Not  To Be  Used  Avoid  water on
              adjacent fires; Special Hazards of Combustion Products: Irritating and toxic hydrogen chloride formed
              when involved in fires; Behavior in Fire: Becomes gaseous and causes irritation. Forms hydrogen
              chloride (hydrochloric acid) by reaction with water used to fight adjacent fires; Ignition Temperature:
              Not pertinent; Electrical Hazard Not pertinent; Burning Rate: Not pertinent.
              Chemical  Reactivity -  Reactivity  with  Water: Reacts  with  water  to  form  hydrogen  chloride
              (hydrochloric acid); Reactivity with Common Materials: Corrodes metal; Stability During Transport:
              Stable; Neutralizing Agentsfor Aciak and Caustics: Flush with water, rinse with sodium bicarbonate
              or lime solution; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
