Prolonged or repeated exposure may cause: Kidney/Bladder Effects: Signs/symptoms may include changes in urine production, abdominal or lower back pain, increased protein in urine, increased blood urea nitrogen (BUN), blood in urine, and painful urination. Carcinogenicity: Contains a chemical or chemicals which can cause cancer. Ingredient C.A.S. No. Class Description Regulation ETHYLBENZENE 100-41-4 Group 2B 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: 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. SECTION 5: FIRE FIGHTING MEASURES 5.1 FLAMMABLE PROPERTIES Autoignition temperature No Data Available Flash Point 103 ºF [Test Method: Pensky-Martens Closed Cup] [Details: ASTM D93] Flammable Limits - LEL 1.00 % Flammable Limits - UEL 7.00 % OSHA Flammability Classification: Class II Combustible Liquid 5.2 EXTINGUISHING MEDIA Use fire extinguishers with class B extinguishing agents (e.g., dry chemical, carbon dioxide). 5.3 PROTECTION OF FIRE FIGHTERS Special Fire Fighting Procedures: Wear full protective equipment (Bunker Gear) and a self-contained breathing apparatus (SCBA). Water may not effectively extinguish fire; however, it should be used to keep fire-exposed containers and surfaces cool and prevent explosive rupture. Unusual Fire and Explosion Hazards: Combustible liquid and vapor. Closed containers exposed to heat from fire may build pressure and explode. Vapors may travel long distances along the ground or floor to an ignition source and flash back. Note: See STABILITY AND REACTIVITY (SECTION 10) for hazardous combustion and thermal decomposition information. SECTION 6: ACCIDENTAL RELEASE MEASURES Accidental Release Measures: Refer to other sections of this MSDS for information regarding physical and health hazards, respiratory protection, ventilation, and personal protective equipment. Call 3M-HELPS line (1-800-364-3577) for more information on handling and managing the spill. Evacuate unprotected and untrained personnel from hazard area. The spill should be cleaned up by qualified personnel. Remove all ignition sources such as flames, smoking materials, and electrical spark sources. Use only non- sparking tools. Ventilate the area with fresh air. For large spill, or spills in confined spaces, provide mechanical ventilation to disperse or exhaust vapors, in accordance with good industrial hygiene practice. Warning! A motor could be an ignition source and could cause flammable gases or vapors in the spill area to burn or explode. Contain spill. For larger spills, cover drains and build dikes to prevent entry into sewer systems or bodies of water. Cover spill area with a fire-extinguishing foam designed for use on solvents, such as alcohols and acetone, that can dissolve in water. An AR - AFFF type foam is recommended. Working from around the edges of the spill inward, cover with bentonite, vermiculite, or commercially available inorganic absorbent material. Mix in sufficient absorbent until it appears dry. Remember, adding an absorbent material does not remove a toxic, corrosivity or flammability hazard. Collect as much of the spilled material as possible using non-sparking tools. Clean up residue with detergent and water. Collect the resulting residue containing solution. Place in a metal container approved for transportation by appropriate authorities. Seal the container. Dispose of collected material as soon as possible. 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 eye contact with vapors, mists, or spray. Avoid skin contact. Avoid breathing of vapors, mists or spray. Use general dilution ventilation and/or local exhaust ventilation to control airborne exposures to below Occupational Exposure Limits. If ventilation is not adequate, use respiratory protection equipment. Do not ingest. Do not eat, drink or smoke when using this product. Wash exposed areas thoroughly with soap and water. Keep away from heat, sparks, open flame, pilot lights and other sources of ignition. Ground containers securely when transferring contents. Wear low static or properly grounded shoes. Avoid static discharge. Avoid contact with oxidizing agents.

Storage

Store away from acids. Store away from heat. Store away from oxidizing agents. Store out of direct sunlight. Keep container in well-ventilated area. SECTION 8: EXPOSURE CONTROLS/PERSONAL PROTECTION 8.1 ENGINEERING CONTROLS Use general dilution ventilation and/or local exhaust ventilation to control airborne exposures to below Occupational Exposure Limits and/or control mist, vapor, or spray. If ventilation is not adequate, use respiratory protection equipment. Provide local exhaust ventilation at transfer points. Provide appropriate local exhaust ventilation on open containers. 8.2 PERSONAL PROTECTIVE EQUIPMENT (PPE) 8.2.1 Eye/Face Protection Avoid eye contact with vapors, mists, or spray. The following eye protection(s) are recommended: Safety Glasses with side shields. 8.2.2 Skin Protection Avoid skin contact. 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. Gloves made from the following material(s) are recommended: Fluoroelastomer (Viton), Nitrile Rubber. 8.2.3 Respiratory Protection Avoid breathing of vapors, mists or spray. Select one of the following NIOSH approved respirators based on airborne concentration of contaminants and in accordance with OSHA regulations: Half facepiece or fullface air-purifying respirator with organic vapor cartridges and P100 particulate prefilters. Consult the current 3M Respiratory Selection Guide for additional information or call 1-800-243-4630 for 3M technical assistance. 8.2.4 Prevention of Swallowing Do not eat, drink or smoke when using this product. Wash exposed areas thoroughly with soap and water. 8.3 EXPOSURE GUIDELINES Ingredient Authority Type Limit Additional Information ALUMINUM OXIDE ACGIH TWA, particulate 10 mg/m3 Table A4 matter, < 1% crystalline silica ALUMINUM OXIDE CMRG TWA 1 fiber/cc ALUMINUM OXIDE OSHA TWA, respirable 5 mg/m3 Table Z-1 ALUMINUM OXIDE OSHA TWA, Vacated, as 10 mg/m3 dust ALUMINUM OXIDE OSHA TWA, as total dust 15 mg/m3 Table Z-1 ETHYLBENZENE ACGIH TWA 100 ppm Table A3 ETHYLBENZENE ACGIH STEL 125 ppm Table A3 ETHYLBENZENE OSHA TWA 100 ppm Table Z-1A ETHYLBENZENE OSHA STEL 125 ppm Table Z-1A GLYCERIN ACGIH TWA, as mist 10 mg/m3 GLYCERIN OSHA TWA, as mist, 5 mg/m3 Table Z-1 respirable GLYCERIN OSHA TWA, Vacated, as 10 mg/m3 mist, total dust GLYCERIN OSHA TWA, as mist, total 15 mg/m3 Table Z-1 dust HYDROTREATED HEAVY NAPHTHA 3M TWA 100 ppm (PETROLEUM) HYDROTREATED HEAVY NAPHTHA CMRG TWA 300 ppm (PETROLEUM) HYDROTREATED LIGHT PETROLEUM CMRG TWA 300 ppm DISTILLATES ISOPROPYL ALCOHOL ACGIH TWA 200 ppm Table A4 ISOPROPYL ALCOHOL ACGIH STEL 400 ppm Table A4 ISOPROPYL ALCOHOL OSHA TWA 400 ppm Table Z-1A ISOPROPYL ALCOHOL OSHA STEL 500 ppm Table Z-1A KEROSENE ACGIH TWA, as total 200 mg/m3 Skin Notation*;Table A3 hydrocarbon vapor KEROSENE CMRG TWA 500 ppm MEDIUM ALIPHATIC SOLVENT CMRG TWA 100 ppm NAPHTHA OIL MIST, MINERAL ACGIH TWA, as mist 5 mg/m3 OIL MIST, MINERAL ACGIH STEL, as mist 10 mg/m3 OIL MIST, MINERAL OSHA TWA, as mist 5 mg/m3 Table Z-1 STODDARD SOLVENT ACGIH TWA 100 ppm STODDARD SOLVENT OSHA TWA, Vacated 100 ppm Table Z-1A STODDARD SOLVENT OSHA TWA 500 ppm Table Z-1 TRIETHANOLAMINE ACGIH TWA 5 mg/m3 VEGETABLE OIL MISTS OSHA TWA, as mist 10 mg/m3 Table Z-1A VEGETABLE OIL MISTS (EXCEPT ACGIH TWA, as mist 10 mg/m3 CASTOR, CASHEW, OR SIMILAR IRRITANT OILS) WHITE MINERAL OIL (PETROLEUM) CMRG TWA 5 mg/m3 WHITE MINERAL OIL (PETROLEUM) CMRG STEL 10 mg/m3 * Substance(s) refer to the potential contribution to the overall exposure by the cutaneous route including mucous membrane and eye, either by airborne or, more particularly, by direct contact with the substance.
