5.2 EXTINGUISHING MEDIA
Material will not burn. 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: Water may be used to blanket the fire. Wear full protective equipment (Bunker Gear) and a
self-contained breathing apparatus (SCBA).
Unusual Fire and Explosion Hazards: No unusual fire or explosion hazards are anticipated.
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. 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. 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. 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.
