 MATERIAL SAFETY DATA SHEET 16-101 3M General Purpose Contact Cleaner 06/23/09

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: 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.

SECTION 5: FIRE FIGHTING MEASURES

5.1 FLAMMABLE PROPERTIES

Flash Point 53.0 ºF [Test Method: Tagliabue Closed Cup]

Flammable Limits - LEL 6.0 % volume
Flammable Limits - UEL 36.5 % volume
OSHA Flammability Classification: 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: Water may not effectively extinguish fire; however, it should be used to keep fire-exposed
containers and surfaces cool and prevent explosive rupture. See Hazardous Decomposition section for products of combustion. 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. Contact with aluminum or zinc in a pressurized system may generate hydrogen gas which could create an
explosion hazard. Vapors may travel long distances along the ground or floor to an ignition source and flash back. Aerosol container
contains gas under pressure. Aerosol container contains flammable material under pressure.

Note: See STABILITY AND REACTIVITY (SECTION 10) for hazardous combustion and thermal decomposition
information.

SECTION 6: ACCIDENTAL RELEASE MEASURES

Accidental Release Measures: If possible, seal leaking container. Place leaking containers in a well-ventilated area, preferably an
operating exhaust hood, or if necessary outdoors on an impermeable surface until appropriate packaging for the leaking container or
its contents is available.

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. Avoid contact with incompatible materials listed in the Reactivity Data Section. 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. Collect the resulting residue containing solution. Seal the container. 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.

SECTION 7: HANDLING AND STORAGE

7.1 HANDLING
Do not eat, drink or smoke when using this product. Wash exposed areas thoroughly with soap and water. Keep away from aluminum
and zinc. Contents may be under pressure, open carefully. Keep away from heat, sparks, open flame, pilot lights and other sources of
ignition. Ground containers securely when transferring contents. Wear low static or properly grounded shoes. Do not pierce or burn
container, even after use. No smoking while handling this material. Do not spray near flames or sources of ignition. Avoid breathing
of vapors, mists or spray. Avoid prolonged or repeated skin contact. Avoid vapor contact with open flame, welding arcs or other high
temperature sources which may cause vapor decomposition to produce toxic gases. Aerosol container contains flammable gas under
pressure. Avoid breathing of airborne material. Avoid static discharge. Avoid eye contact with vapors, mists, or spray. Keep out of
the reach of children. For industrial use only. Not intended for use as a medical device or drug. For industrial or professional use
only. Not intended for consumer sale or use. No smoking: Smoking while using this product can result in contamination of the
tobacco and/or smoke and lead to polymer fume fever caused by the formation of the hazardous decomposition products mentioned in
the Reactivity Data section of this MSDS. Avoid contact with oxidizing agents.

7.2 STORAGE
Store away from acids. Store away from heat. Store out of direct sunlight. Keep container in well-ventilated area. Keep container

pharmaceuticals. Store away from oxidizing agents.

SECTION 8: EXPOSURE CONTROLS/PERSONAL PROTECTION

8.1 ENGINEERING CONTROLS

Use with appropriate local exhaust ventilation. Provide appropriate local exhaust ventilation on open containers. Use in an enclosed
process area is recommended. Use with functioning spray booth or local exhaust. Do not use in a confined area or areas with little or
no air movement. Local exhaust ventilation with a minimum capture velocity of 100 linear feet per minute should be provided for
applications at or above the boiling temperature. Use general dilution ventilation and/or local exhaust ventilation to control airborne
exposures to below Occupational Exposure Limits and/or control mist, vapor, or spray. If ventilation is not adequate, use respiratory
protection equipment.

8.2 PERSONAL PROTECTIVE EQUIPMENT (PPE)

8.2.1 Eye/Face Protection
Avoid eye contact with vapors, mists, or spray.
The following eye protection(s) are recommended: Indirect Vented Goggles.

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.

HMIS Hazard Classification
