**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. Contact with water liberates extremely flammable
gases. May form explosive peroxides. Irritating to eyes, respiratory
system and skin.Water-reactive.Moisture sensitive.Stench.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation.
Ingestion:
May cause irritation of the digestive tract. May cause liver and
kidney damage. 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.
May cause headache. May be harmful if swallowed.
Inhalation:
Causes respiratory tract irritation. May cause effects similar to
those described for ingestion. May be harmful if inhaled. Exposure
to high concentrations may produce narcosis, nausea and loss of
consciousness.
Chronic:
Prolonged or repeated skin contact may cause defatting and
dermatitis.
**** 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. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes.
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:
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:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Reacts violently with water giving off flammable
gas which may explode. Extremely flammable liquid and vapor. This
substance reacts with water to form gases which might cause closed
containers to rupture. Will be easily ignited by heat, sparks or
flame. Vapors may form an explosive mixture with air. Containers may
explode when heated. 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 dry chemical to fight fire. DO NOT USE WATER!
**** 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. Clean up spills immediately,
observing precautions in the Protective Equipment section. Remove all
sources of ignition. Use a spark-proof tool. Provide ventilation.
Approach spill from upwind.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Do not allow water to get into the container
because of violent reaction. Ground and bond containers when
transferring material. Use spark-proof tools and explosion proof
equipment. 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. Container should be opened by a technically
qualified person. 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 heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Store in a dry area.
Keep under a nitrogen blanket. Store in a cool, dry, well-ventilated
area away from incompatible substances. Refrigerator/flammables.
Regularly check inhibitor levels to maintain peroxide levels below
1%. After opening, purge container with nitrogen before reclosing.
Periodically test for peroxide formation on long-term storage.
Addition of water or appropriate reducing materials will lessen
peroxide formation. Containers should be dated when opened and tested
periodically for the presence of peroxides. Should crystals form in a
peroxidizable liquid, peroxidation may have occurred and the product
should be considered extremely dangerous. In this instance, the
container should only be opened remotely by professionals. All
peroxidizable substances should be stored away from heat and light
and be protected from ignition sources.
**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****
Engineering Controls:
Use adequate general or local exhaust ventilation to keep airborne
concentrations below the permissible exposure limits.
