SECTION 2: Hazards identification

3.1 EMERGENCY OVERVIEW Odor, Color, Grade: Solid Abrasive Product General Physical Form: Solid Immediate health, physical, and environmental hazards: This document covers only the 3M product. For complete assessment, when determining the degree of hazard, the material being abraded must also be considered.

Potential 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. Skin Contact: Mechanical Skin irritation: Signs/symptoms may include abrasion, redness, pain, and itching. Inhalation: Dust from 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 and quartz silica. Cancer of the lungs has been associated with titanium dioxide, and cancer of the lungs and silicosis have been associated with quartz (crystalline) silica. No exposure to titanium dioxide or quartz (crystalline) silica is anticipated during normal intended use of 3M Coated Abrasives and Surface Conditioning Products. No detectable levels of these materials were found when simulated grinding air sampling studies were conducted on analogous coated abrasive and surface conditioning constructions that contained similar to or greater concentrations of titanium dioxide and crystalline silica. Therefore, the associated with titanium dioxide and quartz (crystalline) silica are not expected during the intended use of this product Ingredient C.A.S. No. Class Description Regulation Quartz Silica 14808-60-7 Grp. 1: Carcinogenic to International Agency for Research on Cancer humans SILICA, CRYSTALLINE (AIRBORNE SEQ677 Grp. 1: Carcinogenic to International Agency for Research on Cancer PARTICLES OF RESPIRABLE SIZE) humans SILICA, CRYSTALLINE (AIRBORNE SEQ677 Known human carcinogen National Toxicology Program Carcinogens PARTICLES OF RESPIRABLE SIZE) Titanium Dioxide 13463-67-7 Grp. 2B: Possible human carc. International Agency for Research on Cancer SECTION 4: FIRST AID MEASURES 4.1 FIRST AID PROCEDURES The following first aid recommendations are based on an assumption that appropriate personal and industrial hygiene practices are followed. Eye Contact: Flush eyes with large amounts of water. If signs/symptoms persist, get medical attention. Skin Contact: Wash affected area with soap and water. If signs/symptoms develop, get medical attention. Inhalation: Remove person to fresh air. If signs/symptoms develop, get medical attention. If Swallowed: No need for first aid is anticipated. SECTION 5: FIRE FIGHTING MEASURES 5.1 FLAMMABLE PROPERTIES Autoignition temperature Not Applicable Flash Point Not Applicable Flammable Limits(LEL) Not Applicable Flammable Limits(UEL) Not Applicable 5.2 EXTINGUISHING MEDIA Ordinary combustible material. Use fire extinguishers with class A extinguishing agents (e.g., water, foam). 5.3 PROTECTION OF FIRE FIGHTERS Special Fire Fighting Procedures: Wear full protective equipment (Bunker Gear) and a self-contained breathing apparatus (SCBA). Unusual Fire and Explosion Hazards: None inherent in this product. Note: See STABILITY AND REACTIVITY (SECTION 10) for hazardous combustion and thermal decomposition information. SECTION 6: ACCIDENTAL RELEASE MEASURES 6.1. Personal precautions, protective equipment and emergency procedures Not applicable. 6.2. Environmental precautions Not applicable. Clean-up methods Not applicable. In the event of a release of this material, the user should determine if the release qualifies as reportable according to local, state, and federal regulations. 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.

Storage

Store in a cool, dry place. SECTION 8: EXPOSURE CONTROLS/PERSONAL PROTECTION 8.1 ENGINEERING CONTROLS Provide ventilation adequate to control dust concentrations below recommended exposure limits and/or control dust. Warning: Excessive operating speed or generation of extreme heat may result in harmful emissions. Use local exhaust ventilation. 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 Occupational 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 Glasses 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. Wash hands after handling and before eating. 8.3 EXPOSURE GUIDELINES Ingredient Authority Type Limit Additional Information Quartz Silica ACGIH TWA, respirable 0.025 mg/m3 fraction Quartz Silica OSHA TWA concentration, 0.1 mg/m3 respirable Quartz Silica OSHA TWA concentration, 0.3 mg/m3 as total dust Silicon Carbide Mineral ACGIH TWA, as fiber 0.1 fiber/cc Silicon Carbide Mineral ACGIH TWA, respirable 3 mg/m3 fraction Silicon Carbide Mineral ACGIH TWA, inhalable 10 mg/m3 fraction Silicon Carbide Mineral OSHA TWA, respirable 5 mg/m3 fraction Silicon Carbide Mineral OSHA TWA, as total dust 15 mg/m3 Titanium Dioxide ACGIH TWA 10 mg/m3 Titanium Dioxide CMRG TWA, as respirable 5 mg/m3 dust Titanium Dioxide OSHA TWA, as total dust 15 mg/m3 SOURCE OF EXPOSURE LIMIT DATA: ACGIH: American Conference of Governmental Industrial Hygienists CMRG: Chemical Manufacturer Recommended Guideline OSHA: Occupational Safety and Health Administration AIHA: American Industrial Hygiene Association Workplace Environmental Exposure Level (WEEL)
