**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. May form explosive peroxides. Irritating to eyes
and respiratory system.Hygroscopic (absorbs moisture from the air).
Potential Health Effects
Eye:
Contact with eyes may cause severe irritation, and possible eye
burns. Vapors may cause eye irritation. Contact may cause
ulceration of the conjunctiva and cornea.
Skin:
May cause skin irritation. 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.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. Causes respiratory tract irritation.
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 immediately.
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:
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. Forms peroxides of
unknown stability. Flammable liquid and vapor.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. Use water spray to cool fire-exposed
containers. 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.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Use only in a well-ventilated area. Avoid contact with eyes, skin,
and 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.
Prevent build up of vapors to explosive concentration.
Storage:
Keep away from heat, sparks, and flame. Store in a cool place in the
original container and protect from sunlight. Keep refrigerated.
(Store below 4C/39F.) 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:
Use adequate ventilation to keep airborne concentrations low.
