**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. Reacts violently with water liberating extremely
flammable gases. May form explosive peroxides. Causes burns.Light
sensitive.Air sensitive.Water-reactive.
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. May be harmful if swallowed.
Inhalation:
Inhalation of high concentrations may cause central nervous system
effects characterized by nausea, headache, dizziness, unconsciousness
and coma. Causes chemical burns to the respiratory tract. Vapors may
cause dizziness or suffocation. Inhalation may cause coughing,
difficulty breathing and loss of consciousness.
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. May cause lung damage.
Narcotic in high concentrations.
**** 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 immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes.
Ingestion:
Do not induce vomiting. Get medical aid immediately. If swallowed,
do not induce vomiting unless directed to do so by medical personnel.
Never give anything by mouth to an unconscious person. Get medical
aid.
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:
Treat symptomatically and supportively. Persons with skin problems
or liver, kidney, lung, or blood diseases may be at increased risk
from exposure to this substance.
**** 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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Will burn
if involved in a fire. Water Reactive. Material will react with water
and may release a flammable and/or toxic gas. May form explosive
peroxides. May re-ignite after fire is extinguished. 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 carbon dioxide. Use dry chemical to fight fire. DO NOT
USE WATER! Contact professional fire-fighters immediately.
**** 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. Avoid runoff into storm sewers and
ditches which lead to waterways. 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:
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. Handle under an inert atmosphere. Do not allow
contact with water. Use only in a chemical fume hood. Do not
pressurize, cut, weld, braze, solder, drill, grind, or expose empty
containers to heat, sparks or open flames. Keep away from heat,
sparks and flame.
Storage:
Keep away from sources of ignition. Store in a cool, dry place. Do
not store in direct sunlight. Store in a tightly closed container.
Keep from contact with oxidizing materials. Flammables-area.
Corrosives area. Water free area. Store under nitrogen. 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:
Facilities storing or utilizing this material should be equipped
with an eyewash facility and a safety shower. Use adequate general or
local explosion-proof ventilation to keep airborne levels to
acceptable levels.

**** SECTION 10 - STABILITY AND REACTIVITY ****
Chemical Stability:
Stable. However, may decompose if exposed to moist air or water.
Combines vigorously or explosively with water. Under normal storage
conditions, peroxidizable compounds can form and accumulate peroxides
which may explode when subjected to heat or shock. This material is
most hazardous when peroxide levels are concentrated by distillation
or evaporation. THF should never be distilled to dryness. Prolonged
exposure to air, even from extended storage time, can deplete BHT
inhibitor and rapidly accelerate THF-peroxide formation.
Conditions to Avoid:
Light, ignition sources, contact with water, excess heat, evaporating
to near dryness, prolonged exposure to air, confined spaces.
Incompatibilities with Other Materials:
Sodium aluminum hydride, sodium tetrahydroaluminate, lithium
tetrahydroaluminate, borane, metal halides, strong oxidizing agents,
strong acids, oxygen, caustic alkalis, bromine, water.
