**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Highly flammable. Reacts violently with water liberating extremely
flammable gases. May form explosive peroxides. Causes severe
burns.Water-reactive.
Potential Health Effects
Eye:
Causes eye burns.
Skin:
Causes skin burns. May be absorbed through the skin.
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. Do NOT allow victim to rub eyes or keep eyes closed.
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. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. Do NOT use
mouth-to-mouth resuscitation. If breathing has ceased apply
artificial respiration using oxygen and a suitable mechanical device
such as a bag and a mask.
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. Will burn if involved in a fire. Water Reactive.
Material will react with water and may release a flammable and/or
toxic gas. Use water spray to keep fire-exposed containers cool.
Forms peroxides of unknown stability. Flammable liquid and vapor. May
form explosive peroxides. 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 approved class D extinguishing agents or smother with dry sand,
clay, or sodium bicarbonate. Do NOT use water, carbon dioxide, or
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. Use water spray to dilute spill to
a non-flammable mixture. 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. A vapor suppressing foam may be used
to reduce vapors.
**** SECTION 7 - HANDLING and STORAGE ****
Handling:
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. 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. 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.
Store in a tightly closed container. Flammables-area. Corrosives
area. Water free area. Regularly check inhibitor levels to maintain
peroxide levels below 1%. 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.

Eyes:
Wear chemical splash goggles.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.

Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
A respiratory protection program that meets OSHA's 29

**** SECTION 10 - STABILITY AND REACTIVITY ****
Chemical Stability:
Air sensitive. Reacts violently with water. Moisture sensitive.
Light sensitive. 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:
Ignition sources, exposure to air, excess heat, exposure to moist air
or water, evaporating to near dryness, confined spaces, direct
sunlight..
Incompatibilities with Other Materials:
Sodium aluminum hydride, sodium tetrahydroaluminate, lithium
tetrahydroaluminate, borane, metal halides, strong oxidizing agents,
strong acids, oxygen, caustic alkalis, bromine.
