2. Hazards Identification
EMERGENCY OVERVIEW: DANGER!Flammable liquid and vapor. Vapors may cause flash fire or explosion. Vapors can form an
ignitable mixture with air. Vapors can flow along surfaces to a distant ignition source and flash back. Do not smoke. Extinguish all
flames and pilot lights, and turn off stoves, heaters, electric motors and other sources of ignition during use and until all vapors are
gone. Keep container closed and away from heat, sparks, and open flame. Store away from caustics and oxidizers. Avoid breathing
vapor. Avoid skin and eye contact. Use only with adequate ventilation. Prevent build-up of vapors by opening all windows and doors
to achieve cross-ventilation. Irritating to eyes, respiratory system and skin. Harmful or fatal if swallowed. Aspiration hazard if
swallowed - can enter lungs and cause damage. May affect the brain or nervous system causing dizziness, headache or nausea.

4. First-aid Measures
FIRST AID - INHALATION: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give
oxygen. Get medical attention immediately. NOTE: Only trained personnel should administer artificial respiration or give oxygen.
FIRST AID - SKIN CONTACT: Wash skin with soap and water for 15 minutes. Get medical aid if symptoms persist. Remove and
wash contaminated clothing. DO NOT try to peel the solidified material from the skin or use solvents or thinners to dissolve it. The
use of vegetable oil or mineral oil is recommended for removal of this material from the skin. Flush exposed area with water while
removing contaminated clothing. Get medical attention if irritation persists. To remove from skin, remove completely with a dry cloth
or paper towel, before washing with detergent and water.
FIRST AID - EYE CONTACT: If material gets into eyes, flush with water immediately for 15 minutes. Consult a physician.
FIRST AID - INGESTION: If swallowed, DO NOT INDUCE VOMITING. Get medical attention immediately.
5. Fire-fighting Measures
UNUSUAL FIRE AND EXPLOSION HAZARDS: Eliminate sources of ignition: heat, electrical equipment, sparks and flames. Vapors
can form an ignitable mixture with air. Vapors can flow along surfaces to a distant ignition source and flash back. Vapors may form
explosive mixtures with air. Containers may explode if exposed to extreme heat. Empty containers retain product residue (liquid
and/or vapor). Vapor can ignite potentially causing an explosion.
SPECIAL FIREFIGHTING PROCEDURES: Wear self-contained breathing apparatus pressure-demand (NIOSH approved or
equivalent) and full protective gear. Use water spray to cool exposed surfaces. Cool fire-exposed containers using water spray.
EXTINGUISHING MEDIA: Carbon Dioxide, Dry Chemical, Foam
6. Accidental Release Measures
ENVIRONMENTAL MEASURES: No Information
STEPS TO BE TAKEN IF MATERIAL IS RELEASED OR SPILLED: NOTE: Review fire hazards before proceeding with clean up.
Immediately eliminate sources of ignition. Keep people away from and upwind of spill/leak. Scrape up dried material and place into
containers. Prevent product from entering drains. Soak up with inert absorbent material and dispose of as hazardous waste. Read
all product instructions before using. Personal protective equipment should include impervious gloves, protective eye wear, and
suitable work clothes.
7. Handling and Storage
HANDLING: KEEP OUT OF REACH OF CHILDREN!DO NOT TAKE INTERNALLY. Remove all sources of ignition. Keep away from
open flames, hot surfaces and sources of ignition. Provide adequate ventilation. Avoid heat, sparks and open flames. Wear
appropriate personal protection. Avoid breathing vapor and contact with eyes, skin and clothing. Use in well ventilated area. Open
all windows and doors or use other means to ensure cross-ventilation and fresh air entry during application and drying. Odor is not an
adequate warning for hazardous conditions. Empty containers retain product residue (liquid and/or vapor). Vapor can ignite
potentially causing an explosion. Wash thoroughly after handling. Do not use in areas where static sparks may be generated.
Intentional misuse by deliberately concentrating and inhaling vapors may be harmful or fatal. Construction and repair activities can
adversely affect indoor air quality. Consult with occupants or a representative (i.e. maintenance, building manager, industrial
hygienist, or safety officer) to determine ways to minimize impact.
STORAGE: Store away from sources of ignition and heat. Do not store at temperatures above 120 degrees F. Store containers
away from excessive heat and freezing. Store away from caustics and oxidizers. Keep containers tightly closed.

Personal Protection
RESPIRATORY PROTECTION: A NIOSH-approved air purifying respirator with an organic vapor cartridge or canister
may be necessary under certain circumstances where airborne concentrations are expected to exceed exposure limits.
If concentrations exceed the exposure limits specified, use of a NIOSH-approved supplied air respirator is
recommended. Where the protection factor is exceeded, use of a Self Contained Breathing Apparatus (SCBA) may be
necessary. If you experience eye watering, headache or dizziness or if air monitoring demonstrates vapor/mist levels
are above applicable limits, wear and appropriate, properly fitted respirator (NIOSH approved) during and after
application. A respiratory protection program that meets the OSHA 1910.134 and ANSI Z88.2 requirements must be
followed whenever workplace conditions warrant a respirator's use.
SKIN PROTECTION: Solvent-resistant gloves.
EYE PROTECTION: Goggles or safety glasses with side shields.
OTHER PROTECTIVE EQUIPMENT: Provide eyewash and solvent impervious apron if body contact may occur.
HYGIENIC PRACTICES: Remove and wash contaminated clothing before re-use.

11. Toxicological Information
EFFECT OF OVEREXPOSURE - INHALATION: Inhalation of vapors may cause irritation of the nose, throat, lungs and respiratory
tract. Inhalation of vapors in high concentration may cause shortness of breath (lung edema). Intentional misuse by deliberately
concentrating and inhaling the contents may be harmful or fatal. Prolonged, repeated or high exposures may cause central nervous
system depression leading to headaches, nausea, drowsiness, dizziness, and possibly narcosis. In extreme cases, may cause loss
of consciousness.
EFFECT OF OVEREXPOSURE - SKIN CONTACT: Harmful if absorbed through the skin. May cause skin irritation. Prolonged and
repeated skin contact may cause dermatitis, drying and defatting due to the solvent properties.
EFFECT OF OVEREXPOSURE - EYE CONTACT: May cause eye irritation. Signs and symptoms may include: pain, tears, swelling,
redness and blurred vision.
EFFECT OF OVEREXPOSURE - INGESTION: Harmful or fatal if swallowed. Ingestion may cause gastrointestinal irritation, nausea,
vomiting and diarrhea. May cause gastrointestinal disturbances with dizziness and central nervous system depression. If ingested,
may cause depressed respiration. Aspiration hazard if swallowed. Aspiration of material into the lungs due to vomiting can cause
chemical pneumonitis, which can be fatal.
CARCINOGENICITY: No Information
EFFECT OF OVEREXPOSURE - CHRONIC HAZARDS: Repeated or prolonged exposure may cause skin, respiratory, kidney and
liver damage. May cause kidney and liver damage as well as developmental and reproductive toxicity. Prolonged or repeated
inhalation of solvent vapors may cause irregular heartbeat. NOTICE: Reports have associated repeated and prolonged occupational
overexposure to solvents with permanent brain and nervous system damage. Symptoms include: loss of memory, loss of intellectual
ability and loss of coordination. Intentional misuse by deliberately concentrating and inhaling the contents may be harmful or fatal.
Overexposure or misuse of toluene can cause liver, kidney, and brain damage as well as cardiac abnormalities. There have been
cases of aplastic anemia from toluene in industrial exposures (ACGIH, 1992). Increased coagulation time and reduced clotting factors
have also been found, which are indicators of damage to the bone marrow (Clayton & Clayton, 1994). Symptoms include: loss of
memory, loss of intellectual ability and loss of coordination.
