Cleanup Methods

ACCIDENTAL RELEASE MEASURES: Personal precautions, protective equipment and emergency procedures: Wear respiratory protection. Avoid breathing vapors, mist or gas. Ensure adequate ventilation. Remove all sources of ignition. Evacuate personnel to safe areas. Beware of vapors accumulating to form explosive concentrations. Vapors can accumulate in low areas. Environmental precautions: Prevent further leakage or spillage if safe to do so. Do not let product enter drains. Discharge into the environment must be avoided. Methods and materials for containment and cleaning up: Contain spillage, and then collect with an electrically protected vacuum cleaner or by wet-brushing and place in container for disposal according to local regulations.
Evacuate and restrict persons not wearing protective equipment from area of spill or leak until cleanup is complete. Remove all ignition sources. Establish forced ventilation to keep levels below explosive limit. Take up very small spills for disposal by absorbing it in vermiculite, dry sand, or earth and disposing in a secured landfill or combustion chamber. Alternatively, cover with sodium bisulfite, add small amount of water, and mix. Then, after 1 hr, flush with large amounts of water and wash site with soap solution. Liquid should not be allowed to enter confined space, such as a sewer, because of potential for explosion. 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.
Initial isolation and protective action distances: Distances shown are likely to be affected during the first 30 minutes after materials are spilled and could increase with time. If more than one tank car, cargo tank, portable tank, or large cylinder involved in the incident is leaking, the protective action distance may need to be increased. You may need to seek emergency information from CHEMTREC at (800) 424-9300 or seek professional environmental engineering assistance from the US EPA Environmental Response Team at (908) 548-8730 (24-hr response line). Small spills (from a small package or a small leak from a large package): First: Isolate in all directions (feet/meters) 300/100. Then: Protect persons downwind (miles/kilometers): Day 0.7/1.1, Night 2.0/3.2. Large spills (from a large package or from many small packages): First: Isolate in all directions (feet/meters) 3000/1000. Then: Protect persons downwind (miles/kilometers): Day 7.0+/11.0+, Night 7.0+/11.0+.
1. Remove all ignition sources. 2. Ventilate the area of spill or leak. 3. for small quantities, absorb on paper towels. evaporate in safe place (such as fume hood). Allow sufficient time for evaporating vapors to completely clear hood ductwork. Burn paper in suitable location away from combustible materials. For large quantities, cover with sodium bisulfite add small amount of water, and mix. Then, after 1 hr, flush with large amt of water, and wash site with soap solution. Liquid should not be allowed to enter confined space, such as sewer, because of possibility of explosion.
Environmental considerations: Land spill: Dig a pit, pond, lagoon, or 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. Neutralize with sodium bisulfate. Apply appropriate foam to diminish vapor and fire hazard. /Acrolein, stabilized/
Environmental considerations: Air spill: Apply water or mist to knock down vapors. Combustion products include corrosive or toxic vapors. /Acrolein, stabilized/
Environmental considerations: Water spill: Use natural barriers or oil spill control booms to limit spill travel. Add sodium bisulfate. 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. /Acrolein, stabilized/
Spills of liquid acrolein are handled by covering the acrolein with 6 inches of National 99 Aero-O-Foam to suppress evaporation; Polymerization of the spilled acrolein by adding a dilute, 5-10% aqueous sodium carbonate solution should then be ... /applied/. Dilute aqueous sodium bisulfite may be used on small spills.
