Barium permanganate

Spill Handling: Evacuate and restrict persons not wearing protective equipment from area of spill or leak until cleanup is complete. Remove all ignition sources. Collect powdered material in the most convenient and safe manner and deposit in sealed containers. Ventilate area of spill or leak after cleanup is complete. It may be necessary to contain and dispose of this chemical as a hazardous waste. If material or contaminated runoff enters waterways, notify downstream users of potentially contaminated waters. Contact your Department of Environmental Protection or your regional office of the federal EPA for specific recommendations.

The sulfate may be brushed up and treated as normal refuse. Soluble barium salts should be scooped up and treated as for waste disposal. Wash the spill area thoroughly with water. /Soluble barium salts/

Environmental considerations - 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./ 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. Absorb bulk liquid with fly ash, cement powder, or commercial sorbents. /Barium/

Environmental considerations - 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. /Barium/

Environmental considerations - air spill: Apply water spray or mist to knock down vapors. /Barium/

If soluble barium compounds are spilled, the following steps should be taken: 1. Ventilate area of spill. 2. Collect spilled material in the most convenient and safe manner and deposit in sealed containers for reclamation or for disposal in a secured sanitary landfill. Liquid containing soluble barium compounds should be absorbed in vermiculite, dry sand, earth, or a similar material. /Soluble barium compounds (as barium)/

The European Community guidelines regard sol barium salts as moderately dangerous for water quality (LD50 5-50 mg/kg) and their removal may be accomplished by diluted sulfuric acid and subsequent neutralization. /Sol barium salts/
