Hazards and Protection.
Storage
Keep in a tightly closed container, stored in a cool, dry, ventilated area. Protect against physical damage. Containers of this material may be hazardous when empty since they retain product residues (dust, solids); observe all warnings and precautions listed for the product.
Protection
Wear protective gloves and clean body-covering clothing. Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
Respirators
If the exposure limit is exceeded, a half-face dust/mist respirator may be worn for up to ten times the exposure limit or the maximum use concentration specified by the appropriate regulatory agency or respirator supplier, whichever is lowest. A full-face piece dust/mist respirator may be worn up to 50 times the exposure limit, or the maximum use concentration specified by the appropriate regulatory agency, or respirator supplier, whichever is lowest. For emergencies or instances where the exposure levels are not known, use a full-facepiece positive-pressure, air-supplied respirator. WARNING: Air-purifying respirators do not protect workers in oxygen-deficient atmospheres.
Small spills/leaks
Ventilate area of leak or spill. Wear appropriate personal protective equipment. Sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust dispersal.
Stability
Stable under ordinary conditions of use and storage.
Incompatibilities
Chlorine trifluoride, Ethylene oxide.
Decomposition
Carbon dioxide and carbon monoxide may form when heated to decomposition.

Fire.
Fire fighting
Use any means suitable for extinguishing surrounding fire. In the event of a fire, wear full protective clothing and NIOSH-approved self-contained breathing apparatus with full facepiece operated in the pressure demand or other positive pressure mode.
Fire potential
Not considered to be a fire hazard.
Hazards
Fine dust dispersed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard.

Health.
Exposure limit(s)
OSHA Permissible Exposure Limit (PEL) - alpha alumina (aluminum oxide): 15 mg/m3 total dust, 5 mg/m3 respirable fraction.
Exposure effects
   Ingestion
Extremely large oral dosages may produce gastrointestinal disturbances.
   Inhalation
Hazard is principally that of a nuisance dust. Coughing or shortness of breath may occur in cases of excessive inhalation.
   Skin
May cause irritation with redness and pain.
   Eyes
No adverse effects expected but dust may cause mechanical irritation.

First aid
 
   Ingestion
Give several glasses of water to drink to dilute. If large amounts were swallowed, get medical advice.
   Inhalation
Remove to fresh air. Get medical attention for any breathing difficulty
   Skin
Immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing and shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention if irritation develops.
   Eyes
Immediately flush eyes with plenty of water for at least 15 minutes, lifting upper and lower eyelids occasionally. Get medical attention if irritation persists.
