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: Physical Blockage: Signs/symptoms may include cramping, abdominal pain, and constipation.

Environmental effects

This substance does not leach metals or other RCRA (Resource Conservation and Recovery Act) listed TCLP (Toxic Characteristic Leaching Procedure) hazardous substances at concentrations that would make the product a hazardous waste. 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: Do not induce vomiting unless instructed to do so by medical personnel. Give victim two glasses of water. Never give anything by mouth to an unconscious person. Get medical attention.

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 clothing, including helmet, self-contained, positive pressure or pressure demand breathing apparatus, bunker coat and pants, bands around arms, waist and legs, face mask, and protective covering for exposed areas of the head. Unusual Fire and Explosion Hazards: Not applicable. Note: See STABILITY AND REACTIVITY (SECTION 10) for hazardous combustion and thermal decomposition information. SECTION 6: ACCIDENTAL RELEASE MEASURES Accidental Release Measures: 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 Avoid breathing of dust created by cutting, sanding, grinding or machining. For industrial or professional use only.

Storage

Store in a cool place. SECTION 8: EXPOSURE CONTROLS/PERSONAL PROTECTION 8.1 ENGINEERING CONTROLS Use with appropriate local exhaust ventilation. Provide appropriate local exhaust for cutting, grinding, sanding 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. Use in a well- ventilated area. 8.2 PERSONAL PROTECTIVE EQUIPMENT (PPE) 8.2.1 Eye/Face Protection Avoid eye contact. 8.2.2 Skin Protection Select and use gloves and/or protective clothing to prevent skin contact based on the results of an exposure assessment. Consult with your glove and/or protective clothing manufacturer for selection of appropriate compatible materials. 8.2.3 Respiratory Protection Avoid breathing of dust created by cutting, sanding, grinding or machining. 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 ALUMINUM OXIDE MINERAL ACGIH TWA - 10 mg/m3 as particulate; Table A4 specific form ALUMINUM OXIDE MINERAL CMRG TWA 1 fiber/cc ALUMINUM OXIDE MINERAL OSHA TWA - 5 mg/m3 Table Z-1 respirable ALUMINUM OXIDE MINERAL OSHA TWA, 10 mg/m3 Vacated - as dust ALUMINUM OXIDE MINERAL OSHA TWA - as total 15 mg/m3 Table Z-1 dust VAC Vacated PEL:Vacated Permissible Exposure Limits [PEL] are enforced as the OSHA PEL in some states.
