ACCIDENTAL RELEASE MEASURES PERSONAL PRECAUTIONS : Restrict access to area as appropriate until clean-up operations are complete. Stop or reduce any leaks if it is safe to do so. Ventilate spill area if possible. Do not touch spilled material. Remove sources of ignition. Have emergency equipment (for fires, spills, leaks, etc.) readily available. Use personal protective equipment recommended in Section 8 (Exposure Controls/Personal Protection). Notify appropriate government, occupational health and safety and environmental authorities. METHODS FOR CLEANING UP : SMALL SPILLS: Soak up spill with absorbent material. Place residues in a suitable, covered, properly labeled container. Wash affected area. LARGE SPILLS: Contain liquid using absorbent material, by digging trenches or by diking. Reclaim into recovery or salvage drums or tank truck for proper disposal. Clean contaminated surfaces with water or aqueous cleaning agents. Contact an approved waste hauler for disposal of contaminated recovered material. Dispose of material in compliance with regulations indicated in Section 13 (Disposal Considerations). ENVIRONMENTAL PRECAUTIONS : Do not contaminate surface water. 7. HANDLING AND STORAGE HANDLING : Use with adequate ventilation. Keep the containers closed when not in use. Do not take internally. Do not get in eyes, on skin, on clothing. Have emergency equipment (for fires, spills, leaks, etc.) readily available. STORAGE CONDITIONS : Store away from heat and sources of ignition. Store separately from oxidizers.

I'm not in any way supporting dispersants but to be fair - this is NOT being sprayed on men, women, and children... it is being injected into the oil at 5,000 feet under the gulf. Still bad, just making a point of clarification.
