Incompatibility (Material to avoid):
Avoid acids of all types with a pH < 4.0
Hazardous Decomposition or Byproducts
In use, dust and decomposing odors may be generated. In most cases, the material removed from the workplace 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 VI - Health Hazard Data
Route(s) of Entry: Inhalation? Skin? Ingestion?
During normal use
Affects breathing, irritation Irritation None
Health Hazards (Acute and Chronic)
ACUTE: Dust may be slightly irritating to eyes and respiratory tract at high concentrations. CHRONIC: May affect
breathing capacity. For products containing phenol/formaldehyde resin dust generated from intended use may contain
trace amounts of phenol and formaldehyde which may cause skin sensitization and airway obstruction. For products
containing inorganic fluorides, excessive exposure to inorganic fluorides has been shown to increase bone density.
Signs and Symptoms of Exposure:
INHALATION: May cause airway obstruction, difficulty breathing. EYES: May irritate eyes. SKIN: May experience skin
irritation from dust. INGESTION: No known adverse affects, but ingestion is not recommended.
Medical Conditions Generally Aggravated by Exposure:
N/A
Emergency and First Aid Procedures
INHALATION: Remove to fresh air. If breathing stops, get medical attention immediately and give artificial respiration.
EYES: Wash with large amounts of water and obtain medical attention if needed. SKIN: Wash affected areas with soap
and water and obtain medical attention if needed. INGESTION: Call poison control center, hospital emergency room, or
physician immediately.
Section VII - Precautions for Safe Handling and Use
Steps to Be Taken in Case Material is Released if Spilled
Follow normal clean up procedures.
Waste Disposal Method
Use standard landfill methods consistent with applicable Federal, State, Provincial, and local laws. Products with listed
fluorides may have slightly soluble fluoride swarf.
Precautions to Be Taken in Handling and Storing
Always handle and store wheels in a careful manner
Other Precautions
ALWAYS visually inspect wheels before mounting, check machine speed against the established maximum safe operating
speed marked on the wheel, check mounting flanges for equal and correct diameter, use mounting blotters, be sure work rest is
properly adjusted, use a safety guard covering at least one-half of the grinding wheel, allow newly mounted wheels to run at
operating speed with guard in place for at least one minute before grinding, and turn off coolant before stopping wheel to avoid
an out-of-balance wheel.
