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.
Chemical splash goggles in compliance with OSHA regulations are advised; however, OSHA regulations also permit other type safety glasses. Whre chemical resistant gloves. To prevent repeated or prolonged skin contact, wear impervious clothing and boots.
Use NIOSH/MSHA approved respirator appropriate for exposure of concern.
Keep material out of water sources and sewers. Build dikes to contain flow as necessary.
Incompatible with acids and bases Incompatible with oxidizing agents.
(Non-Specific -- Arsenic Compound, Solid, n.o.s.) Stay upwind; keep out of low areas. Wear self-contained (positive pressure if available) breathing apparatus and full protective clothing.(Non-Specific -- Arsenic Compound, Solid, n.o.s.) Small fires: dry chemical, carbon dioxide, water spray, or foam. Large fires: water spray, fog, or foam. Move container from fire area if you can do so without risk.
Abnormally low blood pressure and rapid heart rate may develop with acute arsenic poisoning. Toxic delirium and encephalopathy are complications of acute arsenic poisoning; encephalopathy may be permanent. Peripheral neuropathy leading to profound muscular weakness and wasting may be delayed by several weeks after acute exposure; recovery is usually slow or incomplete. No reproductive studies were found for OBPA, but arsenic compounds have been fetotoxic and teratogenic in animals. Arsenic can most likely cross the placenta. One neonatal fatality and several uneventful births have occurred in cases of acute arsenic poisoning in pregnancy. <br>Arsenic is excreted in the breast milk. Lower doses of arsenic have not affected male fertility in animals, but toxic doses have produced effects on the testes.
Induction of vomiting is one of the bases for its use as a military agent. Gastroenteritis, sometimes with watery or bloody diarrhea, occurs with acute exposure to arsenic.
Severe respiratory irritation leading to pulmonary edema would be expected from acute exposure to obpa. Respiratory failure and adult respiratory distress syndrome have occurred in acute arsenic intoxication.
Tearing and burns or strong irritation occur to the eyes. A garlic-like odor may be apparent on the breath.
Do not induce emesis - dilution: following ingestion and/or prior to gastric evacuation, immediately dilute with 4 to 8 ounces (120 to 240 ml) of milk or water (not to exceed 15 ml/kg in a child). The possible benefit of early removal of some ingested material by cautious gastric lavage must be weighed against potential complications of bleeding or perforation.
If symptoms develop, move individual away from exposure and into fresh air. If symptoms persist, seek medical attention. If breathing is difficult, administer oxygen. Keep person warm and quiet; seek immediate medical attention.
Remove all exposed clothing and jewelry taking necessary precautions to prevent secondary exposure to health care providers. Irrigate exposed areas promptly with copious amounts of water for at least 30 minutes. Wash the skin, including hair and nails, vigorously; do repeated soap washings. Discard contaminated clothing.
If symptoms develop, immediately move individual away from exposure and into fresh air. Flush eyes gently with water for at least 15 minutes while holding eyelids apart; seek immediate medical attention.
