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 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.
Hazardous Decomposition Products:
Carbon monoxide, carbon dioxide, hydrogen bromide, oxides of magnesium.
