Steps to be taken in case material is released or spilled:
Wear appropriate respiratory and protective equipment specified in section VIII. Isolate spill area, provide ventilation and extinguish sources of ignition. Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal. Takecare not to raise dust.
Waste disposal method:
Dispose of in accordance with state, local, and federal regulations.
Hazard Label Information:
Store in cool, dry area and in tightly sealed container. Wash thoroughly after handling.
