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
Chronic: May affect breathing capacity.
For products containing phneol/formaldehyde resin, dust generated
from intended use may contain trace amounts of phenol and
formaldehyde which under excessive exposure may cause skin
sensitization and airway obstruction.
For products containing inorganic fluorides,
excessive exposure to inorganic fluorides have been shown to increase
bone density.
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

NORTON USA FORMAT MSDS: ALSICNZRESIN052 Page 2 of 4
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 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
Recommend using local exhaust ventilation when general ventilation is
not keeping the airborne concentration below the TLV.
RESPIRATORY PROTECTION
Respirators are required when airborne contaminant levels exceed the

NORTON USA FORMAT MSDS: ALSICNZRESIN052 Page 3 of 4
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, 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 prodcuts containing inorganic fluorides, thermal decomposition
may produce trace amounts of fluorides.
SECTION 11. TOXICOLOGICAL INFORMATION
CARCINOGENICITY
For wheels containing fiberglass, fiber diameters are greater than
10um, therefore considered non-respirable.
Fiberglass - IARC-3
LD50/LC50
Values are not appropriate or available.
SECTION 12. ECOLOGICAL INFORMATION
CHEMICAL FATE
Resin bonded materials demonstrate similar degradation rates as
Phenolic plastics.
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.
RECYCLING PROGRAM - the Company has developed a grinding
wheel recycling program. If you are interested in returning your
stubs, information can be obtained by dialing Customer Service.
