FIRST AID MEASURES
INHALATION: Remove to fresh air. Give artificial respiration
if not breathing. Get immediate medical attention.
EYE CONTACT: Immediately flush eyes with lots of running water for
15 minutes, lifting the upper and lower eyelids occasionally. Get
immediate attention.
SKIN CONTACT: Immediately wash skin with lots of soap and water.
Remove contaminated clothing and shoes; wash before reuse. Get
medical attention if irritation persists after washing.
INGESTION: Do not induce vomiting. If conscious, give lots of
water. Get immediate medical attention. Do not give anything by
mouth to an unconscious or convulsing person.
NOTES TO PHYSICIAN: The danger of aspiration must be weighed against
toxicity when considering emptying the stomach. Stomach contents should be
emptied quickly in a manner which avoids the vomitus from entering the
lungs.

HEALTH HAZARD INFORMATION
PRIMARY ROUTES OF EXPOSURE: Inhalation, skin or eye contact.
SIGNS AND SYMPTOMS OF EXPOSURE:
INHALATION: Prolonged or repeated exposure or breathing very high
concentration may cause headaches, nausea, vomiting, dizziness,
other central nervous system effects, convulsions, and in extreme
cases, unconsciousness and death.
EYE CONTACT: Vapors will irritate the eyes. Liquid and mists will
irritate and may burn the eyes.
SKIN CONTACT: Brief contact may dry the skin. Prolonged or repeated
contact may irritate the skin causing dermatitis.
INGESTION: Swallowing large quantities causes headaches, nausea,
vomiting, and perhaps unconsciousness. Can also cause liver and
kidney injury.
CHRONIC EFFECTS OF EXPOSURE: No specific information available.
MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE:
Preexisting eye or skin disorders may be aggravated by acetone
exposure. Also, use of alcoholic beverages enhances toxic effects.

CARCINOGENICITY: This material is not considered to be a carcinogen by
the National Toxicology Program, the International Agency for Research on
Cancer, or The Occupational Safety and Health Administration.
OTHER DATA: Development of cataracts has been reported in laboratory
animals after prolonged repeated skin exposure.

ECOLOGICAL INFORMATION SECTION

PERSONAL PROTECTION
VENTILATION: Local mechanical exhaust ventilation capable of
maintaining emissions at the point of use below the PEL.
RESPIRATORY PROTECTION: If use conditions generate vapors or mists, wear a
NIOSH- approved respirator appropriate for those emission levels.
Appropriate respirators may be a full facepiece or half mask air-purifying
cartridge respirator equipped for organic vapors/mists, a self-contained
breathing apparatus in the pressure demand mode, or a supplied-air
respirator.
EYE PROTECTION: Chemical goggles unless a full facepiece respirator is
also worn. It is generally recognized that contact lenses should not be
worn when working with chemicals because contact lenses may contribute to
the severity of an eye injury.
PROTECTIVE CLOTHING: Long-sleeved shirt, trousers, safety shoes,
rubber gloves, and rubber apron.
OTHER PROTECTIVE MEASURES: An eyewash and safety shower should
be nearby and ready for use.

FIRE AND EXPLOSION INFORMATION
FLASH POINT: -15oF METHOD USED: TCC
FLAMMABLE LIMITS IN AIR: LOWER: 2% UPPER: 13%
AUTOIGNITION TEMPERATURE: No data found
EXTINGUISHING MEDIA: Use water spray, dry chemical, CO2 or alcohol foam.
SPECIAL FIREFIGHTING PROCEDURES: Fire fighters should wear self-contained
breathing apparatus and full protective clothing. Use water spray to cool
nearby containers and structures exposed to fire.
UNUSUAL FIRE AND EXPLOSION HAZARDS: Acetone is extremely flammable.
Extinguish all nearby sources of ignition. Avoid accumulation of
water or acetone vapors because aqueous solutions containing more
than 2.5% acetone vapors are flammable. Vapors formed from this
product are heavier than air and may travel along the surface to
a distant sources of ignition and flashback. Explosive vapor-
air mixtures may be formed above the flash point or between the
lower and upper flammable limits.

HAZARDOUS REACTIVITY
STABILITY: Stable
POLYMERIZATION: Will not occur
CONDITIONS TO AVOID: Heat, Sparks, and Open Flames.
MATERIALS TO AVOID: Oxidizers, acids, alkalis, chlorinated compounds.
HAZARDOUS DECOMPOSITION PRODUCTS: May liberate carbon monoxide, carbon
dioxide, and unidentified organic compounds in black smoke.

SPILL, LEAK AND DISPOSAL PROCEDURES
Action to take for spills or leaks: wear protective equipment including
rubber boots, rubber gloves, rubber apron, and a self-
contained breathing apparatus in the pressure demand mode or a supplied-air
respirator. If the spill or leak is small, a full facepiece air-purifying
cartridge respirator equipped for organic vapors may be satisfactory.
In any event, always wear eye protection. Extinguish all ignition
sources and ensure that all handling equipment is electrically grounded.
For small spills or drips, mop or wipe up and dispose of in DOT-approved
waste containers. For large spills, contain by diking with soil or
other non-combustible absorbent materials and then pump into DOT-approved
waste containers; or absorb with non-combustible sorbent material,
place residue in DOT-approved waste containers. Keep out of sewers,
storm drains, surface waters,
and soil.
Comply with all applicable governmental regulations on spill reporting,
and handling and disposal of waste.
DISPOSAL METHODS: Dispose of contaminated product and materials used in
cleaning up spills or leaks in a manner approved for this material.
Consult with appropriate Federal, State and local regulatory agencies.
NOTE: Empty containers can have residues, gases and mists and are
subject to proper waste disposal, as above.
________________________________________________________________
SPECIAL PRECAUTIONS
HANDLING AND STORAGE PRECAUTIONS: Keep away from heat, sparks, and flames.
Store in a cool, dry, well-ventilated place away from incompatible
materials. Vent container frequently, and more often in warm weather, to
relieve pressure. Electrically ground all equipment when handling this
product and use only non-sparking tools. Keep container tightly closed
when not in use.
Do not use pressure to empty container. Wash thoroughly after
handling. Do not get in eyes, on skin, or on clothing.
REPAIR AND MAINTENANCE PRECAUTIONS: Do not cut, grind, weld, or drill on
or near this container.
OTHER PRECAUTIONS: Containers, even those that have been emptied, will
retain product residue and vapors. Always obey hazard warnings and handle
empty containers as if they were full.
