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

EMERGENCY OVERVIEW
Highly flammable. Irritating to skin. Very toxic to aquatic
organisms, may cause long-term adverse effects in the aquatic
environment. Harmful: may cause lung damage if swallowed. Vapours
may cause drowsiness and dizziness.

Potential Health Effects
Eye:
Causes eye irritation. Causes redness and pain. Exposure to high
vapor concentrations may cause irritation.
Skin:
Causes skin irritation. Prolonged and/or repeated contact may cause
defatting of the skin and dermatitis. A single prolonged skin
exposure is not likely to result in the material being absorbed in
harmful amounts.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. Aspiration of material into the lungs may cause chemical
pneumonitis, which may be fatal. May cause central nervous system
depression.
Inhalation:
Causes respiratory tract irritation. May cause narcotic effects in
high concentration. Aspiration may lead to pulmonary edema.
Chronic:
Prolonged or repeated skin contact may cause defatting and
dermatitis.

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

Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid.
Skin:
In case of contact, immediately flush skin with plenty of water.
Remove contaminated clothing and shoes. Get medical aid. Wash
clothing before reuse.
Ingestion:
Potential for aspiration if swallowed. Get medical aid immediately.
Do not induce vomiting unless directed to do so by medical
personnel. Never give anything by mouth to an unconscious person.
Inhalation:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
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. Liquid will float and may reignite on the surface
of water. Extremely flammable liquid and vapor. Vapor may cause flash
fire. Vapors are heavier than air and may travel to a source of
ignition and flash back. Vapors can spread along the ground and
collect in low or confined areas. May accumulate static electricity.
Extinguishing Media:
Water may be ineffective. 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. Do NOT use
straight streams of water. Dry chemical, alcohol foam, carbon
dioxide.

**** 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. Provide ventilation. A vapor suppressing foam
may be used to reduce vapors.

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

Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Use spark-proof tools and explosion proof equipment. Avoid
contact with eyes, skin, and clothing. Empty containers retain
product residue, (liquid and/or vapor), and can be dangerous. Take
precautionary measures against static discharges. Keep container
tightly closed. Do not pressurize, cut, weld, braze, solder, drill,
grind, or expose empty containers to heat, sparks or open flames. Use
only with adequate ventilation. Keep away from heat, sparks and
flame. Avoid breathing vapor or mist.
Storage:
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:
Use process enclosure, local exhaust ventilation, or other
engineering controls to control airborne levels below recommended
exposure limits. Facilities storing or utilizing this material should
be equipped with an eyewash facility and a safety shower. Ventilation
fans and other electrical service must be non-sparking and have an
explosion-proof design.

Wear chemical splash goggles.
Skin:
Wear appropriate gloves to prevent skin exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
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 respirator use.
