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.

Inhalation

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

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.

 

Refractory Ceramic Fiber Information:  THIS PRODUCT CONTAINS REFRACTORY CERAMIC FIBER.  INHALATION AND INJECTION STUDIES ON LABORATORY ANIMALS HAVE PRODUCED CONFLICTING RESULTS CONCERNING THE CARCINOGENICITY OF REFRACTORY CERAMIC FIBERS.  NO DATA ARE AVAILABLE FROM HUMAN EPIDEMIOLOGICAL STUDIES.  THE INTERNATIONAL AGENCY OF RESEARCH ON CANCER (IARC) HAS RECENTLY REVIEWED THE ANIMAL, HUMAN, AND OTHER RELEVANT EXPERIMENTAL DATA ON MAN MADE MINERAL FIBERS TO EVALUATE AND CLASSIFY THE CANCER CAUSING POTENTIAL OF THESE MATERIALS.  BASED ON ITS REVIEW, THE IARC HAS CLASSIFIED CERAMIC FIBERS, ALONG WITH FIBER GLASS WOOL AND MINERAL WOOL AS GROUP 2B CARCINOGENS, POSSIBLE HUMAN CARCINOGEN.  PENDING RESULTS OF FURTHER STUDIES, STRICT ADHERENCE TO RECOMMENDED SAFE WORK PRACTICES IS ADVISED.

 

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.

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.  Physical abrasion may produce small amounts of respirable dusts. Liquid and moist products (groups 2 and 3) should be stored in a sealed container. See precautions under section 8.

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.

High Temperature Conditions:  Service significantly above the product design temperature may increase friability and the possibility of generating airborne fibers or particulates.  While not considered problematic during use, airborne fibers may complicate removal activities.  It is recommended that product use be carefully matched to design parameters.

After Service: AS MANUFACTURED THIS PRODUCT IS AN ALUMINOSILICATE WHICH MAY TRANSFORM UPON HEATING (TEMPERATURES GREATER THAN 1000oC FOR EXTENDED PERIODS OF TIME) TO NON‑HAZARDOUS MULLITE AND CRISTOBALITE (CAS # 14464‑46‑1), A FORM OF CRYSTALLINE SILICA.  REMOVAL OF THIS PRODUCT AFTER USE MAY GENERATE DUSTS.  PROLONGED OR REPEATED INHALATION OF RESPIRABLE FREE CRYSTALLINE SILICA DUST MAY CAUSE DELAYED LUNG INJURY (SILICOSIS).  THE IARC HAS CLASSIFIED CRYSTALLINE SILICA AS GROUP 2A, PROBABLE HUMAN CARCINOGEN.  THERE IS SUFFICIENT EVIDENCE OF CARCINOGENICITY IN ANIMALS, BUT LIMITED EVIDENCE IN HUMANS.  OSHA'S FINAL RULE LIMIT AND ACGIH'S TLV FOR RESPIRABLE CRISTOBALITE IS .05 mg/m3.  APPROPRIATE VENTILATION AND RESPIRATORY PROTECTION SHOULD BE PROVIDED IN COMPLIANCE WITH OSHA STANDARDS.  STRICT ADHERENCE TO RECOMMENDED SAFE WORK PRACTICES IS ADVISED.  PRODUCT REMOVAL MUST CONSIDER THE POSSIBILITY OF USAGE ABOVE DESIGN TEMPERATURES.

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

 

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.
