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

EMERGENCY OVERVIEW
Highly flammable. Causes burns. Harmful by inhalation.Corrosive.

Potential Health Effects
Eye:
Causes severe eye irritation and burns. May cause chemical
conjunctivitis and corneal damage.
Skin:
Contact with liquid is corrosive and causes severe burns and
ulceration. May cause skin discoloration. May be harmful if absorbed
through the skin. Substance is readily absorbed through the skin.
May cause cyanosis of the extremities. May cause skin rash (in
milder cases), and cold and clammy skin with cyanosis or pale color.
Ingestion:
May cause severe and permanent damage to the digestive tract. Causes
gastrointestinal tract burns. May cause perforation of the digestive
tract. May cause nausea and vomiting. May be harmful if swallowed.
Ingestion of large amounts may cause CNS depression.
Inhalation:
Causes chemical burns to the respiratory tract. Inhalation may be
fatal as a result of spasm, inflammation, edema of the larynx and
bronchi, chemical pneumonitis and pulmonary edema. Aspiration may
lead to pulmonary edema. Vapors may cause dizziness or suffocation.
May cause burning sensation, coughing, wheezing, laryngitis,
shortness of breath, headache, nausea, and vomiting. Harmful if
inhaled.
Chronic:
Effects may be delayed.

**** 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. 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. Do not use mouth-to-mouth resuscitation if victim
ingested or inhaled the substance; induce artificial respiration with
the aid of a pocket mask equipped with a one-way valve or other
proper respiratory medical device.
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. Containers may
explode in the heat of a fire. Flammable liquid and vapor. Vapors
may be heavier than air. They can spread along the ground and
collect in low or confined areas. Contact with metals may evolve
flammable hydrogen gas. Water hydrolyzes material liberating acidic
gas which in contact with metal surfaces can generate flammable
and/or explosive hydrogen gas. Runoff from fire control or dilution
water may cause pollution.
Extinguishing Media:
Use water spray to cool fire-exposed containers. DO NOT USE WATER!
Do NOT get water inside containers. Most foams will react with the
material and release corrosive/toxic gases. Use dry powder or carbon
dioxide.

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

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Clean up spills immediately, observing precautions in the Protective
Equipment section. Cover with sand, dry lime or soda ash and place in
a closed container for disposal. Remove all sources of ignition. Use
a spark-proof tool. Provide ventilation. Do not get water on spilled
substances or inside containers.

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

Handling:
Ground and bond containers when transferring material. Use
spark-proof tools and explosion proof equipment. Empty containers
retain product residue, (liquid and/or vapor), and can be dangerous.
Keep container tightly closed. Keep away from heat, sparks and
flame. Do not get on skin or in eyes. Do not ingest or inhale. Use
with adequate ventilation. Use and store under nitrogen. 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.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Keep container closed when not in use.
Refrigerator/flammables.

**** 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 explosion-proof ventilation to keep airborne levels to
acceptable levels.
Exposure Limits
CAS# 75-94-5:


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:
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.
