Hazards and Protection.
Keep in a cool, dry, dark location in a tightly sealed container or cylinder. Keep away from incompatible materials, ignition sources and untrained individuals. Secure and label area. Protect containers/cylinders from physical damage.
All chemicals should be considered hazardous. Avoid direct physical contact. Use appropriate, approved safety equipment. Untrained individuals should not handle this chemical or its container. Handling should occur in a chemical fume hood.
Protective gloves and clothing. Face shield or eye protection in combination with breathing protection if in powdered form.
Wear positive pressure self-contained breathing apparatus (SCBA).
Keep material out of water sources and sewers. Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. Cover solids with a plastic sheet to prevent dissolving in rain or fire fighting water. Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Water spill: Use natural barriers or oil spill control booms to limit spill travel. Use natural deep water pockets, excavated lagoons, or sand bag barriers to trap material at bottom. Remove trapped material with suction hoses.
Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use water in flooding quantities as fog. Use alcohol foam, dry chemical or carbon dioxide.
Containers may explode when heated. Runoff may pollute waterways.
Non-combustible, substance itself does not burn but may decompose upon heating to produce corrosive and/or toxic fumes.
TLV (as As): ppm; 0.2 mg/m3 (ACGIH 1991-1992).

Abdominal pain, diarrhea, vomiting. See inhalation.
Actue effects - Cough, sore throat, headache, burning sensation in the throat and chest, labored breathing, weakness, shock or collapse. Irritates the eyes, skin and respiratory tract. May cause effects on the gastrointestinal tract, central nervous and cardiovascular systems and kidneys, resuling in severe gastroenteritis, loss of fluids and electrolytes, shock, cardiac disorders, kidney impairment. Exposure above OEL may result in death. Effects may be delayed.<BR>Chronic effects - dermatitis, skin sensitization. May have effects on the skin, mucous membranes, peripheral nervous system, bone marrow and liver, resulting in pigmentation disorders, perforation of the nasal septum, neuropathy, liver impairment. Carcinogenic to humans.
Seek medical assistance.
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Do not use mouth-to-mouth method if victim ingested or inhaled the substance; induce artificial respiration with the aid of a pocket mask equipped with a one-way valve or other proper respiratory medical device. Administer oxygen if breathing is difficult.
Remove and isolate contaminated clothing and shoes. Remove material from skin immediately. Immediately flush with running water for at least 20 minutes. For minor skin contact, avoid spreading material on unaffected skin.
Immediately flush with running water for at least 20 minutes.
