EMERGENCY OVERVIEW
Appearance: clear, colorless liquid. Flash Point: 15 deg C.
Danger! Flammable liquid and
vapor. Causes eye and skin irritation. Repeated
exposure may cause skin dryness or cracking. May cause respiratory
tract irritation. May cause central nervous system depression.

system, eyes, skin.
Potential Health Effects
Eye:
Causes eye irritation.
Skin:
Causes skin irritation. May be harmful if absorbed through the skin.

May cause irritation of the digestive tract. May be harmful if
swallowed.
Inhalation:
May cause respiratory tract irritation. May be harmful if inhaled.
Chronic:
Prolonged or repeated skin contact may cause dermatitis. Chronic
exposure may cause blood effects. Kidney, lung and central nervous
system effects may also occur.
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.
Skin:
Get medical aid. 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.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:
Treat symptomatically and supportively.
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 may form an explosive mixture with air.
Vapors can travel to a source of ignition and flash back. Will burn
if involved in a fire. Containers may explode in the heat of a fire.
Flammable liquid and vapor.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Use water spray,
dry chemical, carbon dioxide, or chemical foam.
Flash Point: 15 deg C ( 59.00 deg F)
Autoignition Temperature: Not available.
Explosion Limits, Lower:1.70 vol %
Upper: 9.80 vol %
NFPA Rating:
(estimated) Health: 2; Flammability: 3; Instability: 0
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. Do not let this chemical enter the
environment.
Section 7 - Handling and Storage
|
Handling:
Use with adequate ventilation. Use spark-proof tools and explosion
proof equipment. Do not get in eyes, on skin, or on clothing. Keep
away from heat, sparks and flame. Do not ingest or inhale.
Storage:
Keep away from sources of ignition. Store in a cool, dry place.
Store in a tightly closed container. Flammables-area.
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 ventilation to keep airborne
concentrations low.

Based on a log Kow of 1.38, the BCF value for tert-butyl acetate can
be estimated to be 6.6 by a recommended regression-derived equation.
This BCF value suggests that bioconcentration is not significant.
Environmental:
Chemical hydrolysis of tert-butyl acetate in moist, very alkaline
soils (pH approaching 10 or higher) may be important, but hydrolysis
in soils of pH 9 or lower is not expected to be important. Based on
an estimated Koc value of 134, tert-butyl acetate may be subject to
significant leaching in soil. Volatilization from dry soil surfaces
may be rapid.
Physical:
ATMOSPHERIC FATE: tert-Butyl acetate will exist almost entirely in
the vapor-phase in the ambient atmosphere due to its expected high
vapor pressure. The half-life for the vapor-phase reaction of
tert-butyl acetate with photochemically produced hydroxyl radicals
has been estimated to be about 26 days in an average atmosphere
indicating that this reaction may be the dominant atmospheric
degradation mechanism. Physical removal via washout may be possible.
Other:
Do not empty into drains.
Section 13 - Disposal Considerations
|
Chemical waste generators must determine whether a discarded chemical is classified
as a hazardous waste.
US EPA guidelines for the classification determination are listed in 40 CFR Parts 261.3.
Additionally, waste generators must consult state and local hazardous waste regulations to
ensure complete and accurate classification.
