SECTION 2: Hazards identification

29 CFR 1910.1200) 3.1 EMERGENCY OVERVIEW Specific Physical Form: Paste Odor, Color, Grade: smell of mint white colored paste General Physical Form: Solid Immediate health, physical, and environmental hazards: May cause allergic skin reaction. This document has been prepared in accordance with the U.S. OSHA Hazard Communication Standard, which requires the inclusion of all known hazards of the product or ingredients regardless of the potential risk. The risks of the hazards communicated in this document may vary depending on the potential for exposure.

Potential health effects

Eye Contact: Mild Eye Irritation: Signs/symptoms may include redness, pain, and tearing. Skin Contact: Mild Skin Irritation: Signs/symptoms may include localized redness, swelling, and itching. Allergic Skin Reaction (non-photo induced): Signs/symptoms may include redness, swelling, blistering, and itching. Inhalation: This product may have a characteristic odor; however, no adverse health effects are anticipated. Ingestion: Gastrointestinal Irritation: Signs/symptoms may include abdominal pain, stomach upset, nausea, vomiting and diarrhea. Target Organ Effects: This product contains and 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. This product contains Cristobalite (CASRN 14464-46-1). Cancer of the lungs and silicosis has been associated with cristoballite. No exposure to cristobalite is anticipated during normal intended handling of the paste or cured material and therefore, the health effects associated with cristobalite are not expected during the forseeable use of this product. 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: Remove contaminated clothing and shoes. Immediately flush skin with large amounts of water. Get medical attention. Wash contaminated clothing and clean shoes before reuse. Inhalation: No need for first aid is anticipated. 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 No flash point 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: Closed containers exposed to heat from fire may build pressure and explode. 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 Evacuate unprotected and untrained personnel from hazard area. The spill should be cleaned up by qualified personnel. Ventilate the area with fresh air. 6.2. Environmental precautions Place in a closed container approved for transportation by appropriate authorities. Dispose of collected material as soon as possible. Clean-up methods Observe precautions from other sections. Call 3M- HELPS line (1-800-364-3577) for more information on handling and managing the spill. Contain spill. Collect as much of the spilled material as possible. Clean up residue with an appropriate solvent selected by a qualified and authorized person. Ventilate the area with fresh air. Read and follow safety precautions on the solvent label and MSDS. 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. Do not ingest. Wash hands after handling and before eating. Avoid eye contact with dust or airborne particles. 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.

Storage

Store away from heat. Store out of direct sunlight. Store away from areas where product may come into contact with food or pharmaceuticals. SECTION 8: EXPOSURE CONTROLS/PERSONAL PROTECTION 8.1 ENGINEERING CONTROLS Use in an enclosed process area is recommended. Not applicable. Use in a well-ventilated area. Do not use in a confined area or areas with little or no air movement. 8.2 PERSONAL PROTECTIVE EQUIPMENT (PPE) 8.2.1 Eye/Face Protection Avoid eye contact. 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. 8.2.3 Respiratory Protection Under normal use conditions, airborne exposures are not expected to be significant enough to require respiratory protection. 8.2.4 Prevention of Swallowing Not applicable. Do not ingest. Wash hands after handling and before eating. 8.3 EXPOSURE GUIDELINES Ingredient Authority Type Limit
