SECTION 2. COMPOSITION/INFORMATION ON INGREDIENTS

SUBSTANCE DESCRIPTION PERCENT CAS# -------------------------------------------------------------------------------- Aluminum Oxide, Non-fibrous 30.000- 95.000 1344-28-1 Chrome oxide(*) 1.000- 2.000 1308-38-9 Cobalt Aluminate (*) 0.100- 2.000 1345-16-0 Amorphous Silica, Fused 2.000- 30.000 60676-86-0 Silicon Carbide 30.000- 95.000 409-21-2 Sulfur 15.000- 40.000 7704-34-9 OTHER (*)This substance is regulated under Section 313 of the Emergency Planning and Community Right-to-Know Act of 1986 and the Canadian National Pollution Reduction Initiative (NPRI). The grinding wheel may be comprised of only some of the above.

SECTION 3. HAZARDS IDENTIFICATION

INHALATION ACUTE EXPOSURE EFFECTS Dust may be slightly irritating to eyes and respiratory tract at high concentrations. INHALATION CHRONIC EXPOSURE EFFECTS May affect breathing capacity. For products containing Amorphous Silica, Fused, there is limited evidence in animals that excessive and prolonged exposure to this chemical may cause pulmonary fibrosis The chrome and Cobalt are fused into the glass matrix and are expected to pose little risk. EYE CONTACT ACUTE EXPOSURE EFFECTS Dust may irritate eyes. SKIN CONTACT ACUTE EXPOSURE EFFECTS Some may experience skin irritation from dust. INGESTION ACUTE EXPOSURE EFFECTS No known adverse effects, but ingestion not recommended.

SECTION 4. FIRST AID MEASURES

INHALATION Remove to fresh air. If breathing has stopped, give artificial respiration. Get medical attention immediately. SKIN CONTACT Wash affected areas with soap and water. Obtain medical assistance. EYE CONTACT Wash with large amounts of water. Obtain first aid and medical assistance, if needed. INGESTION Call poison control center, hospital emergency room or physician immediately.

SECTION 5. FIRE FIGHTING MEASURES

FIRE FIGHTING PROCEDURES Not Applicable HAZARDOUS PRODUCTS/COMBUSTION None. HAZARD RATING SOURCE NFPA HEALTH 1 FLAMMABILITY 0 REACTIVITY 0 OTHER

SECTION 6. ACCIDENTAL RELEASE MEASURES

CLEAN-UP Follow normal clean up procedures.

SECTION 7. HANDLING AND STORAGE

HANDLING Always HANDLE AND STORE wheels in a CAREFUL manner. Always VISUALLY INSPECT all wheels before mounting. Always CHECK MACHINE SPEED against the established maximum safe operating speed MARKED ON THE WHEEL. Always CHECK MOUNTING FLANGES for equal and correct diameter. Always USE MOUNTING BLOTTERS. Always be sure WORK REST is properly adjusted. Always USE A SAFETY GUARD covering at least one-half of the grinding wheel. Always allow NEWLY MOUNTED WHEELS to run at operating speed, with guard in place, for at least one minute before grinding. Always TURN OFF COOLANT before stopping wheel to avoid creating an out-of-balance wheel

SECTION 8. EXPOSURE CONTROLS/PERSONAL PROTECTION

VENTILATION PROTECTION Handle with adequate ventilation. See OSHA 29 CFR 1910.94 (ventilation) and 29 CFR 1910.1000 (Air contaminants). RESPIRATORY PROTECTION Respirators are required when airborne contaminant levels exceed the TLV(s). EYE PROTECTION Always WEAR SAFETY GLASSES or some type of eye protection when grinding. OTHER PROTECTION Use of this product may create elevated sound levels. Hearing protection should be worn where required (see OSHA 29 CFR 1910.134 and other applicable regulations).

SECTION 9. PHYSICAL AND CHEMICAL PROPERTIES

APPEARANCE & ODOR Solid article. Odorless.

SECTION 10. STABILITY AND REACTIVITY

INCOMPATIBILITIES Avoid acids of all types with a pH < 4.0. DECOMPOSITION In use, dusts and decomposing odors may be generated. In most cases, the material removed from the workpiece will be significantly greater than the grinding wheel components. Coolants may produce other decomposition products. For products containing phenol and formaldehyde resin, thermal decomposition may produce trace amounts of phenol and formaldehyde. For products containing inorganic fluorides, thermal decomposition may produce trace amounts of fluorides.

SECTION 11. TOXICOLOGICAL INFORMATION

CARCINOGENICITY Silica, Amorphous, Fused - IARC-3, NIOSH-X Cobalt-IARC 2B, Chrome (III) - IARC-3 LD50/LC50 Values are not appropriate or available.

SECTION 12. ECOLOGICAL INFORMATION

CHEMICAL FATE Vitrified products do not appreciably decay.

SECTION 13. DISPOSAL CONSIDERATIONS

WASTE DISPOSAL Use standard landfill methods consistent with applicable Federal, State, Provincial and local laws. Products with listed flourides may have slightly soluble flouride swarf.
