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

EMERGENCY OVERVIEW
Harmful if swallowed. Causes burns.

Potential Health Effects
Eye:
Causes eye burns.
Skin:
Causes skin burns.
Ingestion:
Causes gastrointestinal tract burns. May be harmful if swallowed.
Inhalation:
May cause severe irritation of the respiratory tract with sore
throat, coughing, shortness of breath and delayed lung edema.
Chronic:
Effects may be delayed. Ethanol is mainly metabolized in the liver,
which is also one of the primary target organs. While ethanol is
well known to cause cirrhosis of the liver in alcoholics, liver
cirrhosis has also been produced in rabbits exposed by inhalation.

**** 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. Do NOT allow victim to rub eyes or keep eyes closed.
Extensive irrigation with water is required (at least 30 minutes).
Skin:
Get medical aid immediately. Flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse. Destroy contaminated 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 breathing is difficult, give oxygen. Do NOT use
mouth-to-mouth resuscitation. If breathing has ceased apply
artificial respiration using oxygen and a suitable mechanical device
such as a bag and a mask.
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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Contact
with water liberates highly flammable gases.
Extinguishing Media:
Do NOT use water directly on fire. Use foam, dry chemical, or carbon
dioxide. Do NOT get water inside containers.

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

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

Handling:
Do not get in eyes, on skin, or on clothing. Keep container tightly
closed. Do not ingest or inhale. Use with adequate ventilation. Do
not allow contact with water. Discard contaminated shoes. Keep from
contact with moist air and steam.
Storage:
Keep container closed when not in use. Store in a cool, dry,
well-ventilated area away from incompatible substances. Corrosives
area. Store protected from moisture. Store under nitrogen.

**** 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 general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
Exposure Limits
CAS# 919-30-2:


Personal Protective Equipment

Eyes:
Wear chemical splash goggles.
Skin:
Wear appropriate protective 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. Wear a NIOSH/MSHA
or European Standard EN 149 approved full-facepiece
airline respirator in the positive pressure mode with
emergency escape provisions.
