Hazards and Protection.
Store away from incompatible materials. Keep container tightly closed.
Work with material in a wet state to prevent emission of airborne fibers. Do not breathe dust, get in eyes or on skin and clothing.
In the laboratory, gloves and protective clothing should always be worn but should not be assumed to provide full protection. Carefully fitted masks or respirators may be necessary when working with particulates or gases, and disposable plastic aprons might provide additional protection. Protective clothing should be of distinctive color, as a reminder not to be worn outside the laboratory.
Half-mask respirater with HEPA filter. At high concentrations, use a powered air-purifying respirator with HEPA filter.
Adequately wet with water to form a slurry. Scoop up and place in a container for disposal. Tightly seal the container.
Stable at normal temperatures and pressures.
Strong oxidizing agents.
Toxic and hazardous gases.
Wear a self-contained breathing apparatus in pressure-demand, MSHA/NIOSH (approved or equivalent), and full protective gear. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Use agent most appropriate to extinguish fire.
