SECTION 2: Hazards identification

29 CFR 1910.1200) 3.1 EMERGENCY OVERVIEW Specific Physical Form: Paste Odor, Color, Grade: Odorless, white General Physical Form: Solid Immediate health, physical, and environmental hazards:

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. Inhalation: No health effects are expected. Ingestion: Gastrointestinal Irritation: Signs/symptoms may include abdominal pain, stomach upset, nausea, vomiting and diarrhea. Target Organ Effects: This product contains Cristobalite (CASRN 14464-46-1). Cancer of the lungs and silicosis has been associated with cristobalite. 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: Wash affected area with soap and water. If signs/symptoms develop, get medical attention. 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 Not Applicable Flammable Limits - LEL Not Applicable Flammable Limits - UEL Not Applicable 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). 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 Accidental Release Measures: Observe precautions from other sections. 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. Ventilate the area with fresh air. 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

NFPA Hazard Classification Health 1 Flammability 1 Reactivity 0 Special 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.
