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

EMERGENCY OVERVIEW
Flammable. Causes burns.Moisture sensitive.Lachrymator (substance
which increases the flow of tears).

Potential Health Effects
Eye:
Causes eye burns. Lachrymator (substance which increases the flow
of tears).
Skin:
Causes skin burns.
Ingestion:
Causes gastrointestinal tract burns.
Inhalation:
Causes chemical burns to the respiratory tract.
Chronic:
Chronic exposure may cause effects similar to those of acute
exposure.

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

Eyes:
Do NOT allow victim to rub eyes or keep eyes closed. In case of
contact, immediately flush eyes with plenty of water for at least 15
minutes. Get medical aid immediately.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
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. Do NOT use mouth-to-mouth
resuscitation.
Notes to Physician:
Treat symptomatically and supportively.

**** 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. During a fire, irritating and highly toxic gases may be
generated by thermal decomposition or combustion. Flammable liquid
and vapor. Combustible liquid. Vapors may be heavier than air. They
can spread along the ground and collect in low or confined areas.
Runoff from fire control or dilution water may cause pollution.
Extinguishing Media:
Use carbon dioxide or dry chemical.

**** 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. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation. Do
not get water inside containers.

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

Handling:
Ground and bond containers when transferring material. Use
spark-proof tools and explosion proof equipment. Do not breathe dust,
vapor, mist, or gas. Do not get in eyes, on skin, or on clothing.
Empty containers retain product residue, (liquid and/or vapor), and
can be dangerous. Keep container tightly closed. Do not ingest or
inhale. Use only in a chemical fume hood. Discard contaminated shoes.
Do not pressurize, cut, weld, braze, solder, drill, grind, or expose
empty containers to heat, sparks or open flames. Keep from contact
with moist air and steam. Keep away from heat, sparks and flame.
Storage:
Keep away from heat, sparks, and flame. Store in a cool, dry place.
Store in a tightly closed container. Flammables-area. Store
protected from moisture.

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

Engineering Controls:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate
ventilation to keep airborne concentrations low.
Exposure Limits
CAS# 98-31-7:

Personal Protective Equipment

Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
