**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Extremely flammable. May form explosive peroxides. Irritating to
eyes, respiratory system and skin.
Potential Health Effects
Eye:
Contact with eyes may cause severe irritation, and possible eye
burns. Contact may cause ulceration of the conjunctiva and cornea.
Lachrymator (substance which increases the flow of tears).
Skin:
Causes 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. Extremely flammable
liquid and vapor. Forms peroxides of unknown stability. Containers
may explode in the heat of a fire.
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. Use a
spark-proof tool.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Use only in a well-ventilated area. Use spark-proof tools and
explosion proof equipment. Avoid contact with eyes, skin, and
clothing. 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.
Storage:
Keep away from heat, sparks, and flame. Store in a cool place in the
original container and protect from sunlight. Flammables-area.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
