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

EMERGENCY OVERVIEW
Highly flammable. Harmful if swallowed.Flammable liquid.Toxic.

Potential Health Effects
Eye:
May cause eye irritation. May cause chemical conjunctivitis and
corneal damage.
Skin:
May cause irritation and dermatitis. May cause cyanosis of the
extremities.
Ingestion:
Harmful if swallowed. May cause gastrointestinal irritation with
nausea, vomiting and diarrhea. Ingestion of large amounts may cause
CNS depression. Ingestion may cause headache, nausea, and vomiting.
Inhalation:
Harmful if inhaled. May cause respiratory tract irritation.
Aspiration may lead to pulmonary edema. Vapors may cause dizziness
or suffocation. May cause burning sensation in the chest.
Chronic:
No information found.

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

Eyes:
Immediately flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid
immediately.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid immediately. Do NOT induce vomiting. If conscious and alert,
rinse mouth and drink 2-4 cupfuls of milk or water.
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 may form an explosive mixture with air.
Vapors can travel to a source of ignition and flash back. During a
fire, irritating and highly toxic gases may be generated by thermal
decomposition or combustion. Will burn if involved in a fire. Use
water spray to keep fire-exposed containers cool. Water may be
ineffective. Material is lighter than water and a fire may be spread
by the use of water. Flammable liquid and vapor. Will be easily
ignited by heat, sparks or flame. Containers may explode if exposed
to fire.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Water may be
ineffective. Do NOT use straight streams of water. In case of fire,
use carbon dioxide, dry chemical powder or appropriate foam.

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

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Avoid runoff into storm sewers and ditches which lead to waterways.
Wash area with soap and water. Clean up spills immediately,
observing precautions in the Protective Equipment section. Cover
with an activated carbon adsorbent and place into a closed container
for disposal. Remove all sources of ignition. Use a spark-proof
tool. Provide ventilation.

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

Handling:
Wash thoroughly after handling. Use with adequate ventilation.
Ground and bond containers when transferring material. Use
spark-proof tools and explosion proof equipment. Do not get in eyes,
on skin, or on clothing. Empty containers retain product residue,
(liquid and/or vapor), and can be dangerous. Keep away from heat,
sparks and flame. Store protected from light. Do not pressurize, cut,
weld, braze, solder, drill, grind, or expose empty containers to
heat, sparks or open flames. Do not breathe vapor.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a cool, dry place. Refrigerator/flammables. Keep
containers tightly closed.

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

Engineering Controls:
Use adequate general or local explosion-proof ventilation to keep
airborne levels to acceptable levels.
Exposure Limits
CAS# 1072-43-1:


Personal Protective Equipment

Eyes:
Wear safety glasses and chemical goggles if splashing
is possible.
Skin:
Wear appropriate protective gloves and clothing to
prevent skin exposure.
Clothing:
Wear appropriate protective clothing to minimize
contact with skin.
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. Wear a NIOSH/MSHA
or European Standard EN 149 approved full-facepiece
airline respirator in the positive pressure mode with
emergency escape provisions.
