3. HAZARDS IDENTIFICATION
Inhalation Acute Exposure Effects: Dust may be slightly irritating to eyes and respiratory tract at high concentrations.
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.

4. FIRST AID MEASURES
Inhalation: Remove to fresh air. If breathing has stopped, give artificial respiration. Get medical attention immediately.
Skin Contact: Wash affected area 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.

5. FIRE FIGHTING MEASURES
Firefighting Procedures: Not applicable
Hazardous Products / Combustion: None

6. ACCIDENTAL RELEASE PROCEDURES
Clean-up: Follow normal clean up procedures.

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.
