followed.

_________________________________________________________________________________________________
3M MATERIAL SAFETY DATA SHEET 3M(TM) Safety-Walk(TM) Brand Edge Sealing Compound 03/08/2006

Eye Contact: Flush eyes with large amounts of water. If signs/symptoms persist, get medical attention.

attention. Wash contaminated clothing and clean shoes before reuse.

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.

OSHA Flammability Classification:

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: Water may not effectively extinguish fire; however, it should be used to keep fire-exposed
containers and surfaces cool and prevent explosive rupture. Wear full protective equipment (Bunker Gear) and a self-contained
breathing apparatus (SCBA).

Unusual Fire and Explosion Hazards: Flammable 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. An aqueous film
forming foam (AFFF) 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 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 metal container approved for transportation by appropriate authorities. Seal the container. Dispose of collected
material as soon as possible.
