**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. May form explosive peroxides. Repeated exposure
may cause skin dryness or cracking. Vapours may cause drowsiness and
dizziness.Air sensitive.
Potential Health Effects
Eye:
Causes mild eye irritation.
Skin:
May cause skin irritation. Excessive drying of the skin may result
from repeated or prolonged contact.
Ingestion:
Aspiration hazard. 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.
Aspiration of material into the lungs may cause chemical
pneumonitis, which may be fatal.
Inhalation:
May cause respiratory tract irritation. May cause narcotic effects
in high concentration. May cause drowsiness, unconsciousness, and
central nervous system depression.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Chronic
inhalation may cause effects similar to those of acute inhalation.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid if irritation develops or persists. Wash clothing
before reuse. Rinse area with large amounts of water for at least 15
minutes.
Ingestion:
Do not induce vomiting. 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:
Containers can build up pressure if exposed to heat and/or fire. As
in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Use water spray to keep fire-exposed containers
cool. Water may be ineffective. Material is lighter than water and a
fire may be spread by the use of water. Forms peroxides of unknown
stability. Extremely flammable liquid and vapor. Vapor may cause
flash fire. Vapors are heavier than air and may travel to a source of
ignition and flash back. Vapors can spread along the ground and
collect in low or confined areas.
Extinguishing Media:
Use water spray, dry chemical, carbon dioxide, or chemical foam.
**** 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.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Ground and bond containers when
transferring material. Use spark-proof tools and explosion proof
equipment. Loosen closure cautiously before opening. Avoid contact
with eyes, skin, and clothing. Empty containers retain product
residue, (liquid and/or vapor), and can be dangerous. If peroxide
formation is suspected, do not open or move container. Do not
pressurize, cut, weld, braze, solder, drill, grind, or expose empty
containers to heat, sparks or open flames. Use only with adequate
ventilation. Avoid breathing vapor.
Storage:
Keep away from sources of ignition. Store in a tightly closed
container. Keep under a nitrogen blanket. Keep from contact with
oxidizing materials. Store in a cool, dry, well-ventilated area away
from incompatible substances. Keep away from strong acids. Store
protected from light. Containers should be dated when opened and
tested periodically for the presence of peroxides. Test for peroxide
levels in unpreserved product upon expiration. Products with
excessive peroxide must be disposed of promptly and properly.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
