Eye Contact:
Mechanical eye irritation: Signs/symptoms may include pain, redness, tearing and corneal abrasion.
Dust created by cutting, grinding, sanding, or machining may cause eye irritation. Signs/symptoms may include redness, swelling,
pain, tearing, and blurred or hazy vision.
Skin Contact:
Mechanical Skin irritation: Signs/symptoms may include abrasion, redness, pain, and itching.
No health effects are expected.
Inhalation:
Dust from cutting, grinding, sanding or machining may cause irritation of the respiratory system. Signs/symptoms may include cough,
sneezing, nasal discharge, headache, hoarseness, and nose and throat pain.
Prolonged or repeated exposure may cause:
Pneumoconiosis: Sign/symptoms may include persistent cough, breathlessness, chest pain, increased amounts of sputum, and changes
in lung function tests.
Ingestion:
No health effects are expected.
This product contains titanium dioxide. Cancer of the lungs has been associated with titanium dioxide. No exposure to titanium
dioxide is anticipated during normal intended use of 3M Coated Abrasives, Surface Conditioning, and Ceramic Grain Products. No
detectable respirable titanium dioxide was found when simulate d grinding air sampling studies were conducted on analogous coated
abrasive and surface conditioning constructions that contained similar to or greater concentrations of titanium dioxide. No detectable
respirable titanium dioxide was noted when air sampling studies were conducted on processing ceramic grains containing similar to or
greater concentrations of titanium dioxide. Therefore, the health effects associated with titanium dioxide are not expected during the
intended use of this product.

SECTION 7: HANDLING AND STORAGE
7.1 HANDLING
For industrial or professional use only. Avoid breathing of dust created by sanding, grinding or machining. Avoid eye contact with
dust or airborne particles. Damaged product can break apart during use and cause serious injury to face or eyes. Check product for
damage such as cracks or nicks prior to use. Replace if damaged. Always wear eye and face protection when working at sanding or
grinding operations or when near such operations. Sparks and particles flying from the product during sanding or grinding can cause
injury and fire.
7.2 STORAGE
Store in a cool, dry place.
SECTION 8: EXPOSURE CONTROLS/PERSONAL PROTECTION
8.1 ENGINEERING CONTROLS
Provide ventilation adequate to control dust concentrations belowrecommended exposure limits and/or control dust. Provide
appropriate local exhaust ventilation for sanding, grinding or machining. Use general dilution ventilation and/or local exhaust
ventilation to control airborne exposures to belowOccupational Exposure Limits and/or control dust, fume, or airborne particles. If
ventilation is not adequate, use respiratory protection equipment.
8.2 PERSONAL PROTECTIVE EQUIPMENT (PPE)

8.2.1 Eye/Face Protection
Avoid eye contact. To minimize the risk of injury to face and eyes, always wear eye and face protection when working at sanding or
grinding operations or when near such operations.
The following eye protection(s) are recommended: Safety G lasses with side shields
.
8.2.2 Skin Protection
Avoid skin contact. Wear appropriate gloves to minimize risk of injury to skin from contact with dust or physical abrasion from
grinding or sanding.
8.2.3 Respiratory Protection
Avoid breathing of dust created by sanding, grinding or machining. Assess exposure concentrations of all materials involved in the
work process. Consider material being abraded when determining the appropriate respiratory protection. Select and use appropriate
respirators to prevent inhalation overexposure.
An exposure assessment may be needed to decide if a respirator is required. If a respirator is needed, use respirators as part of a full
respiratory protection program. Based on the results of the exposure assessment, select from the following respirator type(s) to reduce
inhalation exposure:
Half facepiece or full facepiece air-purifying respirator suitable for particulates
For questions about suitability for a specific application, consult with your respirator manufacturer.
8.2.4 Prevention of Swallowing
Not an expected route of exposure. Do not eat, drink or smoke when using this product. Wash exposed areas thoroughly with soap
and water.

National Fire Protection Association (NFPA) hazard ratings are designed for use by emergency response personnel to address the hazards that are
presented by short-term, acute exposure to a material under conditions of fire, spill, or similar emergencies. Hazard ratings are primarily based on the
inherent physical and toxic properties of the material but also include the toxic properties of combustion or decomposition products that are known to
be generated in significant quantities.
