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

EMERGENCY OVERVIEW
Highly flammable. Contact with water liberates extremely flammable
gases. May form explosive peroxides. Causes
burns.Corrosive.Water-reactive.Moisture sensitive.

Potential Health Effects
Eye:
Causes eye burns.
Skin:
Causes skin burns.
Ingestion:
Causes gastrointestinal tract burns. May cause central nervous
system depression, characterized by excitement, followed by headache,
dizziness, drowsiness, and nausea. Advanced stages may cause
collapse, unconsciousness, coma and possible death due to respiratory
failure.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. May cause irritation of the respiratory tract with burning
pain in the nose and throat, coughing, wheezing, shortness of breath
and pulmonary edema. Causes chemical burns to the respiratory tract.
May cause abdominal pain, nausea, vomiting, and inflammation of the
gums and mouth.
Chronic:
May cause liver and kidney damage.

**** 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 immediately. Immediately 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. Reacts violently with water giving off flammable
gas which may explode. Vapors can travel to a source of ignition and
flash back. Water Reactive. Material will react with water and may
release a flammable and/or toxic gas. Containers may explode in the
heat of a fire.
Extinguishing Media:
Do NOT use water directly on fire. Use dry chemical to fight fire.

**** 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. Remove all sources of ignition.
Use a spark-proof tool.

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

Handling:
Do not breathe dust, vapor, mist, or gas. Do not get in eyes, on
skin, or on clothing. Use only in a chemical fume hood.
Storage:
Keep away from heat, sparks, and flame. Store in a cool, dry place.
Store in a tightly closed container. Keep under a nitrogen blanket.
Keep away from water. Flammables-area.

**** 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.

Personal Protective Equipment

Eyes:
Wear safety glasses and chemical goggles if splashing
is possible.
Skin:
Wear appropriate gloves to prevent skin exposure.
Clothing:
Wear a chemical apron.
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.

**** SECTION 10 - STABILITY AND REACTIVITY ****

Chemical Stability:
Prolonged exposure to air and sunlight may form unstable peroxides.
Explosive peroxides may form on concentration. Peroxides can be
detonated by friction, impact, or heating. Peroxide formation may
occur in containers that have been opened and remain in storage.
Normally stable; however, on long term storage, materials containing
similar functional groups form peroxides of unknown stability.
Conditions to Avoid:
Exposure to air, contact with water.
Incompatibilities with Other Materials:
Oxidizing agents, oxygen, alcohols, acids, moist air or water.
Hazardous Decomposition Products:
Carbon monoxide, carbon dioxide, oxides of boron, hydrogen gas.
Hazardous Polymerization: Has not been reported.
