**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Highly flammable.

Potential Health Effects
Eye:
May cause eye irritation.
Skin:
Causes skin irritation. Prolonged and/or repeated contact may cause
defatting of the skin and dermatitis.
Ingestion:
Aspiration hazard. May cause gastrointestinal irritation with
nausea, vomiting and diarrhea. May cause central nervous system
depression, characterized by excitement, followed by headache,
dizziness, drowsiness, and nausea. Advanced stages may cause
collapse, unconsciousness, coma and possible death due to respiratory
failure. Aspiration of material into the lungs may cause chemical
pneumonitis, which may be fatal.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. May cause irritation of the respiratory tract with burning
pain in the nose and throat, coughing, wheezing, shortness of breath
and pulmonary edema.
Chronic:
Prolonged or repeated skin contact may cause defatting and
dermatitis.

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes.
Ingestion:
Do not induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen.
Notes to Physician:

**** SECTION 5 - FIRE FIGHTING MEASURES ****

General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Vapors can travel to a source of ignition and flash
back. Extremely flammable liquid and vapor. Vapor may cause flash
fire. Containers may explode in the heat of a fire. Liquid will float
and may reignite on the surface of water.
Extinguishing Media:
Use water spray to cool fire-exposed containers. This material is
lighter than water and insoluble in water. The fire could easily be
spread by the use of water in an area where the water cannot be
contained. Use dry chemical, carbon dioxide, or alcohol-resistant
foam.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Avoid runoff into storm sewers and
ditches which lead to waterways. Remove all sources of ignition. Use
a spark-proof tool.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Use only in a well-ventilated area. Ground and bond containers when
transferring material. Use spark-proof tools and explosion proof
equipment. Avoid contact with eyes, skin, and clothing. Keep
container tightly closed. Keep away from heat, sparks and flame.
Avoid ingestion and inhalation.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Keep from contact
with oxidizing materials. Store in a cool, dry, well-ventilated area
away from incompatible substances. Flammables-area.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

Engineering Controls:
Local exhaust ventilation may be necessary to control any air
contaminants to within their TLVs during the use of this product.
Ventilation fans and other electrical service must be non-sparking
and have an explosion-proof design.

circumstances where airborne concentrations are
expected. A respiratory protection program that meets
OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or
European Standard EN 149 must be followed whenever
workplace conditions warrant a respirator's use.
