SECTION 2: Hazards identification

OSHA 3.1 EMERGENCY OVERVIEW Specific Physical Form: Paste imbedded on knit fiberglass. Odor, Color, Grade: Liquid resin impregnated on knit fiberglass; slight odor; color varies. General Physical Form: Solid Immediate health, physical, and environmental hazards: May cause allergic skin reaction. May cause allergic respiratory reaction. Air sampling indicates that Isocyanate vapors (4,4'-Methylenediphenyl diisocyanate, CAS# 101-68-8 / 26447- 40-5) are not detectable during use. The limit of detection is 0.00002 parts per million (0.00021 mg/m3). Those people with bronchial problems or with isocyanate sensitivity may respond to low isocyanate concentrations,although no known occurrences have occurred with this product.

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 OSHA Flammability Classification: Not Applicable 5.2 EXTINGUISHING MEDIA DO NOT USE WATER 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: Not applicable. 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 safety precautions on the solvent label and MSDS. Collect the resulting residue containing solution. Place in a closed container approved for transportation by appropriate authorities. 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.
