Hazards and Protection.
Tightly closed containers. Keep away from heat and water.
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.
Wear appropriate protective gloves, clothing and goggles.
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. Water spill: Neutralize with agricultural lime (CaO), crushed limestone (CaCO3), or sodium bicarbonate (NaHCO3). Remove trapped material with suction hoses. Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
Stable to air, light.
Unstable in acids, bases, and toward hydrogen sulfide
Stay upwind; keep out of low areas. Wear self-contained (positive pressure if available) breathing apparatus and full protective clothing.For small fires, use dry chemical, water spray, or foam. For large fires, use water spray, fog, or foam. Use of water may result in generation of toxic fumes.
Poisonous, volatile arsenic oxide may be formed in fires. Exposure of dust to flame may cause explosion. When heated, or on contact with acid or acid fumes, it emits highly toxic fumes. Decomposes readily in the presence of water and carbon dioxide to yield phytotoxic arsenical compounds. Can react vigorously with oxidizing materials. Unstable in acids and bases.
Volatile arsenic oxide may be formed in fires.

Patients may rapidly become hypotensive. Rapid heart rate may develop secondary to pain, hypovolemia, cardiac effects of arsenic or anxiety. Toxic delirium and encephalopathy are possible complications. Peripheral neuropathy is common. Seizures may occur. Trivalent arsenicals have caused teratogenic and embryotoxic effects in the offspring of pregnant mice, rats, and hamsters when administered orally or parenterally. Fetotoxicity and fetal death are possible, but arsenic is NOT likely to be a significant risk to human reproduction at permissible occupational exposure limits. <br>Arsenic is excreted in the breast milk in both experimental animals and humans. <br>Systemic toxicity was present before any effects were noted on the testes.
Early symptoms within hours following arsenic ingestion include abdominal pain, vomiting, profuse bloody or watery (rice-water-like) diarrhea, pain in the extremities and muscles, weakness, and flushing of the skin.
Upper respiratory tract irritation and hoarse voice may result. Acute respiratory failure was seen in a patient with severe arsenic poisoning. Pulmonary edema may occur and be life-threatening. Adult respiratory distress syndrome (ards) has been reported.
Avoid any skin contact. See Inhalation.
Inflammation of the eye, photophobia, dimness of vision, diplopia, and tearing may occur. A garlic-like odor may be detected on the breath.
Gastric decontamination - aggressive decontamination with gastric lavage is recommended. Activated charcoal: administer charcoal as a slurry (240 ml water/30 g charcoal). Usual dose: 25 to 100 g in adults/adolescents.
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.
