3. Hazard Identification
EMERGENCY OVERVIEW
No unusual fire or spill hazard; nuisance-level health risk. Solid abrasive product with no odor.
Potential Health Effects
EYES: Dust from abraded surface may cause mechanical irritation.
SKIN: Some may experience skin irritation from dust.
INHALATION: Overexposure to dust from abraded surface may cause respiratory system irritation.
Hazard degree based on material being abraded.
INGESTION: No adverse health effects expected.
CARCINOGENICITY: None.
4. First Aid Measures
EYES: Flush eyes with plenty of water and call a physician if irritation persists.
P/N: 810-033-100
MATERIAL SAFETY DATA SHEET 02380 Pg. 2
SKIN: Wash affected areas with soap and water. Seek medical assistance.
INHALATION: Provide fresh air, treat for substrate material being abraded.
INGESTION: Call poison control center, hospital emergency room, or physician immediately.
5. Fire Fighting Measures
FLAMMABLE PROPERTIES: Non-flammable.
Flash Point: None. Method Used: Not applicable.
Flammable Limits (% by Volume in Air):
Lower: None. Upper: None.
AUTO-IGNITION TEMPERATURE: Not applicable.
HAZARDOUS COMBUSTION PRODUCTS: Thermal degradation will produce carbon monoxide,
carbon dioxide, and smoke particulates.
EXTINGUISHING MEDIA: Water, carbon dioxide, foam.
FIREFIGHTING INSTRUCTIONS: None.
6. Accidental Release Measures
SMALL/LARGE SPILL: No special procedures.
7. Handling and Storage
HANDLING: Handle with adequate ventilation for nuisance dust.
STORAGE: Keep container closed.
8. Exposure Controls/Personal Protection
VENTILATION PROTECTION: Recommend local exhaust ventilation when general ventilation
can not keep the airborne concentration below the TLV.
ENGINEERING CONTROLS: Not available.
RESPIRATORY PROTECTION: Avoid breathing dust from material being ground. Wear a
particulate respirator where dust is generated.
SKIN AND HAND PROTECTION: Prevent skin contact with dust created from grinding substrate.
EYE AND FACE PROTECTION: Prevent eyes contact with dust created from grinding substrate.
Wear eye protection where dust is generated.
OTHER PROTECTIVE EQUIPMENT: 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).
