Hazards and Protection.
Keep in a cool, dry location. Keep container closed when not in use.
Maintain good housekeeping procedures to prevent accumulation of dust. Use clean up methods which minimize dust generation such as vacuuming or wet cleanup. Wash thoroughly after handling and before eating or smoking and at the end of the work shift. Do not shake clothing or other items to remove dust. Use a vacuum cleaner. Avoid dust inhalation and direct skin contact. Do not ingest.
Safety glasses or goggles are necessary. Gloves are recommended when contact is likely.
Use an appropriate NIOSH approved respirator if airborne dust concentration exceeds the appropriate PEL or TLV.
Remove all sources of ignition. Ventilate area of spill. Clean up using methods which avoid dust generation such as vacuuming (with appropriate filter to prevent airborne dust levels which exceed the PEL or TLV). If airborne dust is generated, use an NIOSH approved respirator.
Cover burning material with an inert powder, such as dry sand or limestone, to exclude oxygen. In case the powder is in drums seal with a suitable lid. For powder fire confined to a small area, use a respirator approved for toxic dust and fumes. For a large fire involving this material, fire fighters should use self-contained breathing apparatus
Dust may present a fire or explosion hazard under favorable conditions. However, this is not expected to be a problem under normal handling conditions.
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. Current scientific evidence indicates no adverse effects are likely from accidental ingestion of small amount of this material.
If substantial quantities are swallowed dilute with a large amount of water, induce vomiting. Seek medical attention.
If any pulmonary symptoms develop, (coughing, wheezing, shortness of breath, etc.) remove from exposure and seek medical attention.
If irritation occurs, thoroughly wash affected area with mild soap and water and prevent further contact. If irritation persists, seek medical attention.
If contact occurs, flush with copious amounts of water. If irritation persists, seek medical attention.
