Hazards and Protection.
Storage
Store away from incompatible materials. Keep container tightly closed.
Handling
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.
Protection
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.
Respirators
Half-mask respirater with HEPA filter. At high concentrations, use a powered air-purifying respirator with HEPA filter.
Small spills/leaks
Adequately wet with water to form a slurry. Scoop up and place in a container for disposal. Tightly seal the container.
Stability
Stable at normal temperatures and pressures.
Incompatibilities
Strong oxidizing agents.
Decomposition
Toxic and hazardous gases.

Fire.
Fire fighting
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.

Exposure effects
The toxological properties of this substance have not been fully investigated.
   Inhalation

Contact a physician, medical facility, or poison control center for advice about whether to induce vomiting. If possible, do not leave individual unattended.
