Section VI - Health Hazard Data
Primary Route(s) of Entry
Acute and Chronic Health Effects and Effects of Overexposure
First Aid and
Medical Information
Inhalation (during grinding)
Acute: Possible cough.
Chronic: May effect breathing capacity.
Remove to fresh air, artificial respiration as needed; Obtain medical assistance.
Ingestion (during grinding)
No known adverse affects, but ingestion not recommended.
Obtain medical assistance.
Skin (during grinding)
Some may experience skin irritation from dust.
Wash affected areas with soap and water; obtain medical assistance.
Eye (during grinding)
Dust may irritate eyes.
Wash with large amounts of water; obtain first aid and medical assistance, if needed.
Other Potential
Health Risks (during grinding)
Grinding may create elevated sound levels which may affect hearing and may aggravate pre-existing respiratory conditions.
Obtain medical assistance, if needed. Remove to fresh air.
Section VII - Precautions For Safe Handling And Use Normal Storage and Handling: See ANSI B7.1.
Normal Use: Handle with adequate ventilation - see OSHA 29CFR1910.94 (Ventilation) and 29CFR1910.1000 (Air Contaminants).
Other Precautions: None.
Steps to be taken in case material is released or spilled: Normal clean up procedures. Evaluate all product in accordance with ANSI B7.1.
Waste disposal method: Standard landfill methods consistent with applicable Federal, State and Local laws. Products containing fluorides may leach a very slight amount in landfills.
