3. Hazard Identification


TARGET ORGANS: Skin, eyes, and lungs
Emergency Overview

CAUTION: Handling or machining of these products may produce respirable dust particles.  Dust may irritate eyes, skin respiratory tract.


Dust may cause irritation or soreness of throat and nose.

Eye Contact

Dust may cause temporary irritation or inflammation.

Skin Contact

May cause temporary dryness, irritation or rash.


Ingestion is unlikely.  May cause gastrointestinal disturbances.  Never induce vomiting without the advice of a physician.

Medical Conditions Aggravated by Exposure: Respiratory effects may be aggravated by smoking.  Pre-existing respiratory problems may be aggravated by dust.


4. First Aid Measures


Inhalation:   Remove to fresh air.  Rinse mouth to clear throat and expel liquid.  Blow nose to evacuate dust.  Consult a physician if irritation persists.

Eye Contact:   Do not rub eyes.  Keep hands or contaminated body parts away from eyes.  Remove contact lenses.  Flush with water.  If irritation persists, consult a physician.

Skin Contact:   Wash with soap and water.  For dryness, a skin cream may be helpful.  Do not apply anything to a rash.  Consult a physician if irritation persists.

Ingestion:   Do not induce vomiting without advice of a physician.  Seek medical attention.

Note to Physicians:   Aluminum Oxide dusts have caused no systemic or pathological problems.  The material is inert in the body.  Some individuals may experience allergic sensitivity reactions.  These are generally limited to mild occupational dermatitis.  Chronic inhalation may result in pleural plaques not associated with cancers.  Other effects principally derived from physical abrasion.

These products contain a small percentage of amorphous silica, however, not in sufficient quantity to produce free crystalline silica upon heating.  Dusts are therefore considered of the inert (nuisance) type and would not be expected to cause permanent damage to tissues on inhalation unless the exposure is severe.  Chronic exposure may produce radioplaque deposits in the pulmonary system with little or no parenchymal  reactions.  Some individuals may exhibit allergenic reactions ranging from asthmatic symptoms to benign pneumoconiosis.




5. Fire Fighting Measures

Materials are not combustible.



6. Accidental Release Measures


Spill Procedures:  Clean up procedures should minimize formation of airborne dusts.  Remove dust by vacuuming using HEPA filtration where possible. Liquid products (groups 3 & 4)  should be cleaned up with sponge, mop or cloth.

Release into Air:  Prevent release of airborne particulates where possible.  Not a regulated hazardous substance.  See section 8 for appropriate engineering controls.

Release into Water:  Release into water is not appropriate.  Not a regulated hazardous substance.  Landfill dusts and debris consistent with local regulations.



7. Handling and Storage


Storage:  These materials are stable and may be stored indefinitely.

Normal Use:  Materials are stable under normal use and are not expected to produce significant hazardous by-products or emissions.

Machining and Cutting:  These materials may produce respirable and nuisance dusts when machined or cut.  See section 8 for exposure controls and personal protection during machining or installation procedures.

After Service:  Product removal must consider the possibility of usage above design temperatures.  See section 8 for appropriate respiratory protection during removal.

Before Service:  See C in Section 15 and MSDS Attachment 1.



8. Exposure Controls


Engineering Controls:

Use dust suppression controls.  Local exhaust ventilation, point of generation dust collection, and/or down-draft work stations to minimize airborne dust generation are recommended when machining product.

Respiratory Protection:

Use appropriate protection pursuant to OSHA 29CFR 1910.134 and 29CFR 1926.103.  The following information is provided as a guide and reflects industry recommendations for control of dust.

PPE < 1.0  f/cc

No specific recommendation, use personal protective equipment based on local conditions.

PPE  1.0 f/cc to 5.0 f/cc

Half-face, air purifying respirator equipped with a high efficiency particulate air (HEPA) filter cartridge.

PPE 5.0 to 25 f/cc

Full-facepiece, air purifying respirator equipped with a high-efficiency particulate air (HEPA) filter cartridge

PPE > 25 f/cc

Full-facepiece, positive pressure, supplied air respirator.

PPE Other

Work clothes should be washed separately and the washing machine rinsed following use.  If possible, do not take work clothes home following machining or removal activities that produce significant amounts of dust.

Skin Protection

Wear gloves, head coverings, and full body clothing to prevent skin irritation.  Disposable clothing may be used.  Store work clothes and street clothes separately.

Eye Protection

Wear safety glasses or chemical goggles to prevent eye contact.  Do not wear contact lenses without goggles.  Do not get dust or liquids into eyes.  Have eye washing facilities available when using products.

These products are generally not hazardous during normal use.  These guidelines are provided for special circumstances involved in machining , use and or after service removals.

See section 7 for after service and section 13 for disposal recommendations.
