Arsenic Trichloride

CAS RN: 7784-34-1

Cleanup Methods

Environmental consideration: Air spill: Apply water spray or mist to knock down vapors. Vapor knockdown water is corrosive or toxic and should be diked for containment.
Environmental consideration: Land spill: Dig a pit, pond, lagoon, holding area to contain liquid or solid material. /SRP: If time permits, pits, ponds, lagoons, soak holes, or holding areas should be sealed with an impermeable flexible membrane liner./ Dike surface flow using soil, sand bags, foamed polyurethane, or foamed concrete. Absorb bulk with fly ash or cement powder.
Environmental consideration: Water spill: Adjust pH to neutral (pH 7). Add calcium hypochlorite. Neutralize with agricultural lime, crushed limestone, or sodium bicarbonate. Add ferric chloride (FeCl3). Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates.
Stop or control the leak, if this can be done without undue risk. Use water spray to disperse vapors and protect personnel. Control runoff and isolate discharged material for proper disposal.
Prompt cleanup and removal are necessary. Control runoff and isolate discharged material for proper disposal.
Floors and other accessible surfaces contaminated with inorganic arsenic may not be cleaned by the use of compressed air, and shoveling and brushing may be used only where vacuuming or other relevant methods have been tried and found not to be effective. /Inorganic arsenic compounds/
