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. Vapors can travel to a source of ignition and flash
back. Will burn if involved in a fire. Wear appropriate protective
clothing to prevent contact with skin and eyes. Wear a
self-contained breathing apparatus (SCBA) to prevent contact with
thermal decomposition products. Extremely flammable liquid and vapor.
Forms peroxides of unknown stability.
Extinguishing Media:
For small fires, use dry chemical, carbon dioxide, water spray or
alcohol-resistant foam. Use water spray to cool fire-exposed
containers. Water may be ineffective. Do NOT use halogenated agents.
DO NOT USE WATER! Use dry chemical.

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. Remove all sources of ignition. Use a
spark-proof tool.
|
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Use only in a well-ventilated area.
Avoid contact with eyes, skin, and clothing. Do not breathe dust,
vapor, mist, or gas. Empty containers retain product residue,
(liquid and/or vapor), and can be dangerous. Keep container tightly
closed. Keep away from heat, sparks and flame. Avoid ingestion and
inhalation. Use and store under nitrogen. Container should be opened
by a technically qualified person. Use only in a chemical fume hood.
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.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a cool place in the original container and
protect from sunlight. Store in a cool, dry place. Store in a
tightly closed container. Keep from contact with oxidizing
materials. Flammables-area. Regularly check inhibitor levels to
maintain peroxide levels below 1%.
|
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 exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.

Personal Protective Equipment
Eyes:
Wear chemical splash goggles. Wear safety glasses and
chemical goggles if splashing is possible.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to minimize
contact with skin.
Respirators:
A NIOSH/MSHA approved or European Standard EN 149 air
purifying respirator with an organic vapor cartridge
or canister may be permissible under certain
circumstances where airborne concentrations are
expected. Follow the OSHA respirator regulations
found in 29 CFR 1910.134 or European Standard EN 149.
Use a NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.

Section 10 - Stability and Reactivity
|
Chemical Stability:
Prolonged exposure to air and sunlight may form unstable peroxides.
Explosive peroxides may form on concentration. Peroxides can be
detonated by friction, impact, or heating. Peroxide formation may
occur in containers that have been opened and remain in storage.
Normally stable; however, on long term storage, materials containing
similar functional groups form peroxides of unknown stability.
Conditions to Avoid:
Normally stable; however, on long term storage, materials containing
similar functional groups form peroxides of unknown stability.,
incompatible materials, light, ignition sources.
Incompatibilities with Other Materials:
It is explosive with potassium hydroxide, sodium hydroxide, and
sodium tetrahydroaluminate since caustic alkalies deplete the
inhibitor. Reacts with potassium dioxide 2-aminophenol to form an
explosive product. Reacts violently with metal halides. Forms
explosive hydrogen gas with borane or lithium tetrahydroaluminate and
reacts vigorously with bromine and calcium hydride+heat. Incompatible
with sulfinyl chloride and oxidizing materials. Hazardous
polymerization may occur in the presence of cationic initiators such
as strong proton acids or selected Lewis acids.
Hazardous Decomposition Products:
Carbon monoxide, carbon dioxide, oxides of boron.
Hazardous Polymerization: Has not been reported.

flow-through bioassay, wt 0.12 g, water hardness 45.5 mg/l CaCO3,
temp:25 +/- 1 deg C, pH 7.5, dissolved oxygen greater than 60% of
saturation.
Environmental:
If released to the atmosphere, tetrahydrofuran will exist solely in
the vapor phase and is degraded in the atmosphere by reaction with
photochemically-produced hydroxyl radicals and nitrate radicals with
half-lives of about 1 and 3 days, respectively. Measured Koc values
of 23 and 18 indicate that tetrahydrofuran will have very high
mobility in soil.
Physical:
Tetrahydrofuran is not expected to adsorb to suspended matter in the
water based on its measured Koc values. This compound should
volatilize from water surfaces. An estimated BCF value of 1 suggests
that tetrahydrofuran will not bioconcentrate in aquatic organisms.
Other:
None
