**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. May form explosive peroxides. Causes burns. Toxic
to aquatic organisms, may cause long-term adverse effects in the
aquatic environment.Hygroscopic (absorbs moisture from the air).
Potential Health Effects
Eye:
Causes eye burns. Vapors may cause eye irritation. Contact may
cause ulceration of the conjunctiva and cornea.
Skin:
Causes skin burns. Prolonged and/or repeated contact may cause
defatting of the skin and dermatitis.
Ingestion:
Harmful if swallowed. May cause gastrointestinal irritation with
nausea, vomiting and diarrhea. Causes gastrointestinal tract burns.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. Causes chemical burns to the respiratory tract.
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:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes. Discard contaminated clothing in a manner which limits
further exposure.
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:
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. Will burn if involved in a fire. 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. Forms peroxides of unknown stability.
Flammable liquid and vapor.
Extinguishing Media:
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. Use water spray to dilute spill to
a non-flammable mixture. 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. Use only in a
chemical fume hood. Prevent build up of vapors to explosive
concentration.
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 cool, dry place. Store in a
tightly closed container. Keep from contact with oxidizing
materials. Flammables-area. Regularly check inhibitor levels to
maintain peroxide levels below 1%.
**** 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.
