First Aid Measures

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.

Handling and Storage

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.

Hazards Identification

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.

Hazards

Fine dust dispersed in air in sufficient concentrations, and in the presence of an ignition source is a potential dust explosion hazard.

Exposure Controls/Personal Protection

Personal 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.

Exposure limit(s)

OSHA Permissible Exposure Limit (PEL) - alpha alumina (aluminum oxide): 15 mg/m3 total dust, 5 mg/m3 respirable fraction.

Fire Fighting Measures

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.

Accidental Release Measures

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 and Reactivity

Incompatibilities

Chlorine trifluoride, Ethylene oxide.

Stability

Stable under ordinary conditions of use and storage.

Decomposition

Carbon dioxide and carbon monoxide may form when heated to decomposition.
