Parathion

CAS RN:56-38-2

Cleanup Methods

1. Ventilate area of spill or leak. 2. Collect for reclamation, or absorb in vermiculite, dry sand, earth, or a similar material.
If material is not on fire & is not involved in fire ... build dikes to contain flow as necessary. Attempt to stop leak if ... /it can be done/ without hazard. ... If material leaking (not on fire) consider evacuation from downwind area based on amount of material spilled, location & weather conditions.
Air spill: Apply water spray to knock down vapors.
Spills of parathion on floors ... absorbed with an absorbing clay. Sweeping compound ... facilitate the removal of all visible traces of parathion contaminated clay.
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 liquid with fly ash, cement powder, or commercial sorbents. Apply "universal" gelling agent to immobilize spill. /Parathion and compressed gas mixture/
Water spill: Use natural barriers or oil spill control booms to limit spill travel. Use surface active agent (eg, detergent, soaps, alcohols), if approved by EPA. Inject "universal" gelling agent to solidify encircled spill and increase effectiveness of booms. If dissolved, in region of 10 ppm or greater concentration, apply activated carbon at ten times the spilled amount. Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates. /Parathion and compressed gas mixture/
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. /Parathion mixture, dry/
Water spill: Use natural deep water pockets, excavated lagoons, or sand bag barriers to trap material at bottom. If dissolved, in region of 10 ppm or greater concentration, apply activated carbon at ten times the spilled amount. Remove trapped material with suction hoses. Use mechanical dredges or lifts to remove immobilized masses of pollutants and precipitates. /Parathion mixture, dry/
