prior to use. Replace if damaged. Always wear eye and face protection when working at sanding or grinding operations or
when near such operations. Combustible dust may form by action of this product on another material (substrate). Dust
generated from the substrate during use of this product may be explosive if in sufficient concentration with an ignition source.
Dust deposits should not be allowed to accumulate on surfaces because of the potential for secondary explosions.

8.2. Exposure controls
8.2.1. Engineering controls
Provide appropriate local exhaust ventilation for sanding, grinding or machining. Use general dilution ventilation and/or
local exhaust ventilation to control airborne exposures to below relevant Exposure Limits and/or control
dust/fume/gas/mist/vapors/spray. If ventilation is not adequate, use respiratory protection equipment. Provide local exhaust at
process emission sources to control exposure near the source and to prevent the escape of dust into the work area. Ensure that
dust-handling systems (such as exhaust ducts, dust collectors, vessels, and processing equipment) are designed in a manner to
prevent the escape of dust into the work area (i.e., there is no leakage from the equipment).
8.2.2. Personal protective equipment (PPE)
Eye/face protection
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. Select and use eye/face protection to prevent contact based on the results of an
exposure assessment. The following eye/face protection(s) are recommended:
Safety Glasses with side shields
Skin/hand protection
Wear appropriate gloves to minimize risk of injury to skin from contact with dust or physical abrasion from grinding or
sanding.
Respiratory protection
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.

SECTION 11: Toxicological information
The information below may not be consistent with the material classification in Section 2 if specific ingredient
classifications are mandated by a competent authority. In addition, toxicological data on ingredients may not be
reflected in the material classification and/or the signs and symptoms of exposure, because an ingredient may be
present below the threshold for labeling, an ingredient may not be available for exposure, or the data may not be
relevant to the material as a whole.
11.1. Information on Toxicological effects
Signs and Symptoms of Exposure
Based on test data and/or information on the components, this material may produce the following health effects:

Eye Contact:
Mechanical eye irritation: Signs/symptoms may include pain, redness, tearing and corneal abrasion.
Dust created by grinding, sanding, or machining may cause eye irritation. Signs/symptoms may include redness, swelling,
pain, tearing, and blurred or hazy vision.
Ingestion:

Carcinogenicity:
Ingredient C.A.S. No. Class Description Regulation

Additional Information:
This document covers only the 3M product. For complete assessment, when determining the degree of hazard, the material
being abraded must also be considered.
This product contains quartz silica. Quartz silica is a form of crystalline silica. Occupational exposure to inhaled crystalline
silica has been associated with silicosis and lung cancer. No exposure to crystalline silica is expected during the normal
handling and use of this product. Crystalline silica was not detected when air sampling was conducted during simulated use of
similar products containing crystalline silica. Therefore, the health effects associated with crystalline silica are not expected
during normal use of this product.

Health: 0 Flammability: 1 Instability: 0 Special Hazards: None
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.
