Hazards and Protection.
Storage
Keep in a cool, dry location in a tightly closed container.
Handling
Keep the container closed, whenever possible. Maintain good housekeeping procedures to prevent accumulation of dust. Use clean up methods which minimize dust generation such as vacuuming or wet clean up. Use an appropriate NIOSH approved respirator if airborne dust concentrations exceed the appropriate PEL or TLV.
Protection
Wear appropriate chemical protective clothing.
Respirators
Wear positive pressure self-contained breathing apparatus.
Small spills/leaks
Remove all sources off ignition. Ventilate the area of the spill. Clean up using methods which avoid the generation of dusts. Such methods include wet mopping or vacuuming (assuring that the vacuum is equipped with the proper filter to prevent airborne dust levels which exceed the PEL or TLV). If airborne dust is generated, use the appropriate NIOSH approved respiratory protection.
Stability
No data.
Incompatibilities
May react vigorously with oxidizing materials. Contact with acids can generate flammable hydrogen gas.

Fire.
Fire fighting
Do not extinguish fire unless flow can be stopped. Do not use water. Use graphite, soda ash, powdered sodium chloride, or suitable dry powder.
Fire potential
Produce flammable gases on contact with water.
Hazards
Produce flammable gases on contact with water. May ignite on contact with water or moist air. Some react vigorously or explosively on contact with water. May be ignited by heat, sparks or flames. May re-ignite after fire is extinguished. Some are transported in highly flammable liquids. Runoff may create fire or explosion hazard.
Combustion products
Fire will produce irritating, corrosive and/or toxic gases.

Exposure effects
The toxological properties of this substance have not been fully investigated.
   Inhalation
Dust inhalation may cause mild irritation of the nose and throat. Skin and eye contact may cause irritation due to abrasive action of the dust.
   Skin
See inhalation.
   Eyes
See Inhalation.

First aid
 
   Ingestion
If substantial quantities are swallowed, dilute with a large amount of water, induce vomiting and seek medical attention.
   Inhalation
Move victim to fresh air. Apply artificial respiration if victim is not breathing. Administer oxygen if breathing is difficult.
   Skin
Remove and isolate contaminated clothing and shoes. In case of contact with substance, wipe from skin immediately. Flush with running water for at least 20 minutes.
   Eyes
Flush with running water for at least 20 minutes.
