**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. Contact with water liberates extremely flammable
gases. May form explosive peroxides. Causes burns.
Potential Health Effects
Eye:
Causes eye burns.
Skin:
Causes skin burns. May be absorbed through the skin. If absorbed,
causes symptoms similar to those of inhalation.
Ingestion:
Causes gastrointestinal tract burns. May cause central nervous
system depression.
Inhalation:
Causes chemical burns to the respiratory tract.
Chronic:
May cause liver and kidney damage. May cause lung damage. Narcotic
in high concentrations.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at least 15 minutes. Get medical aid immediately.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
Ingestion:
If swallowed, do NOT induce vomiting. Get medical aid immediately.
If victim is fully conscious, give a cupful of water. Never give
anything by mouth to an unconscious person.
Inhalation:
If inhaled, remove to fresh air. 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. Forms peroxides of unknown stability. Contact with
water liberates highly flammable gases. 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:
Do NOT use water directly on fire. Use dry chemical to fight fire.
**** 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.
Use a spark-proof tool. Isolate area and deny entry. Provide
ventilation. Do not expose spill to water.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Use spark-proof tools and explosion proof equipment. 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. Take precautionary measures against
static discharges. Keep container tightly closed. Keep away from
heat, sparks and flame. Do not allow contact with water. Prevent
build up of vapors to explosive concentration. Do not pressurize,
cut, weld, braze, solder, drill, grind, or expose empty containers to
heat, sparks or open flames. Use only with adequate ventilation.
Storage:
Keep away from sources of ignition. Store in a cool, dry place.
Store in a tightly closed container. Keep under a nitrogen blanket.
Water free area. 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 explosion-proof ventilation equipment. Facilities storing or
utilizing this material should be equipped with an eyewash facility
and a safety shower. Use adequate general or local exhaust
ventilation to keep airborne concentrations below the permissible
exposure limits.
