||| MSDS "  Alumina Oxide
Product Name : Aluminium Oxide
Other Designations : Activated Alumina, Alpha Alumina
Chemical Formula : Al2O3(contains about 11-12% bound water)
Ingredient CAS No. Percent Hazardous
Aluminium Oxide 1344 - 28 - 1 90 - 100 % Yes

Potential Health Effects
Inhalation : Hazard is principally that of a nuisance dust.
Coughing or shortness of breath may occur in cases of excessive inhalation.

Ingestion : No adverse effects expected.

Eyes : No adverse effects expected but dust may cause mechanical irritation.

Skin : May cause irritation with redness and pain.

Chronic Exposure: No adverse effects expected.

Aggravation of pre-existing Conditions: Not expected to be health hazard.


After inhalation
Remove to fresh air. Get medical attention for any breathing difficulty.

Give several glasses of water to drink to dilute. If large amounts were swallowed, get medical advice.

After skin contact
Immediately flush skin with plenty of water for at least 15 minutes. Remove contaminated clothing & shoes. Wash clothing before reuse. Thoroughly clean shoes before reuse. Get medical attention if irritation develops.

After eye contact
Immediately flush eyes with plenty of water for atleast 15 minutes, lifting upper and lower eyelids occasionally. Get medical attention if irritation persists.


Fire :
Not considered to be a fire hazard.

Explosion :
Not considered to be an explosion hazard.

Fire Extinguishing Media:
Use any means suitable for extinguishing surrounding fire.

Special Information:
Use protective clothing and breathing equipment appropriate for the surrounding fire and to protect against the Aluminium oxide dust that may be dispersed in the air.


Ventilate area of leak or spill. Wear appropriate personal protective equipment as specified in Section 8. Spills: Sweep up and containerize for reclamation or disposal. Vacuuming or wet sweeping may be used to avoid dust dispersal.


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 warning and precautions listed for the product.

Airborne Exposure Limits:
Alumina (Aluminium Oxide)
OSHA Permissible Exposure Limit (PEL):
Activated Alumina, 15 mg/m3 total dust, 5 mg/m3 respirable fraction
ACGIH Threshold Limit Value (TLV) :
Aluminium oxide, 10mg/m3 (TWA) inhalable (total) particulate matter containing no asbestos and < 1% crystalline silica, A4.
Ventilation System:
A system of local and / or general exhaust is recommended to keep employee exposures below the Airborne Exposure Limits. Local exhaust ventilation is generally preferred because it can control the emissions of the contaminant at its source, preventing dispersion of it into the general work area. Please refer to the ACGIH document, Industrial Ventilation, A Manual of Recommended Practices, most recent edition, for details.

Personal Respirators (NIOSH Approved):
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.

Skin Protection
Wear protective gloves and clean body - covering clothing.
Eye Protection
Use chemical safety goggles. Maintain eye wash fountain and quick-drench facilities in work area.
