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

EMERGENCY OVERVIEW
Highly flammable. Contact with water liberates extremely flammable
gases. May form explosive peroxides. Irritating to eyes and
respiratory system.Moisture sensitive.

Potential Health Effects
Eye:
Contact with eyes may cause severe irritation, and possible eye
burns. Vapors may cause eye irritation.
Skin:
May cause skin irritation. May be absorbed through the skin in
harmful amounts. Prolonged and/or repeated contact may cause
defatting of the skin and dermatitis.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May cause headache. May cause unconsciousness. May be
harmful if swallowed. May cause central nervous system depression.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. Causes respiratory tract irritation. May cause narcotic
effects in high concentration.
Chronic:
Prolonged or repeated eye contact may cause conjunctivitis.
Prolonged or repeated skin contact may cause defatting and
dermatitis. 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:
Immediately flush skin with plenty of water for at least 15 minutes
while removing contaminated clothing and shoes. Get medical aid if
irritation develops or persists. Discard contaminated clothing in a
manner which limits further exposure.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Get medical
aid. Wash mouth out with water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:

**** SECTION 5 - FIRE FIGHTING MEASURES ****

General Information:
Vapors can travel to a source of ignition and flash back. Wear
appropriate protective clothing to prevent contact with skin and
eyes. Wear a self-contained breathing apparatus (SCBA) to prevent
contact with thermal decomposition products. Extremely flammable
liquid and vapor. Forms peroxides of unknown stability.
Extinguishing Media:
Do NOT use water directly on fire. Use water spray to cool
fire-exposed containers. Use foam, dry chemical, or carbon dioxide.
Water may be ineffective.

**** 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. Empty containers retain product residue,
(liquid and/or vapor), and can be dangerous. Keep container tightly
closed. Keep away from heat, sparks and flame. Avoid ingestion and
inhalation. Use only in a chemical fume hood. Prevent build up of
vapors to explosive concentration. 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. Store in a cool place in the original container and
protect from sunlight. Store in a tightly closed container.
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 exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.
Exposure Limits
CAS# 45376-40-7:


Personal Protective Equipment

Eyes:
Wear safety glasses and chemical goggles if splashing
is possible.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to minimize
contact with skin.
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.
Conditions to Avoid:
Prolonged exposure to air and sunlight may form unstable peroxides.,
incompatible materials, light, ignition sources, exposure to moist
air or water.
Incompatibilities with Other Materials:
It is explosive with potassium hydroxide, sodium hydroxide, and
sodium tetrahydroaluminate since caustic alkalies deplete the
inhibitor. Reacts with potassium dioxide 2-aminophenol to form an
explosive product. Reacts violently with metal halides. Forms
explosive hydrogen gas with borane or lithium tetrahydroaluminate and
reacts vigorously with bromine and calcium hydride+heat. Incompatible
with sulfinyl chloride and oxidizing materials. Hazardous
polymerization may occur in the presence of cationic initiators such
as strong proton acids or selected Lewis acids.
Hazardous Decomposition Products:
Nitrogen oxides, carbon monoxide, carbon dioxide, oxides of boron,
borane.
Hazardous Polymerization: Has not been reported.
