EMERGENCY OVERVIEW
Appearance: clear, colorless liquid. Flash Point: -29 deg C.
Danger! Extremely flammable liquid and vapor.
Vapor may cause flash fire. Breathing vapors may cause drowsiness
and dizziness. May cause eye, skin, and respiratory tract
irritation.
Target Organs: Central nervous system.
Potential Health Effects
Eye:
May cause eye irritation.
Skin:
Exposure may cause irritation characterized by redness, dryness, and
inflammation.
Ingestion:
May cause irritation of the digestive tract. Aspiration of material
into the lungs may cause chemical pneumonitis, which may be fatal.
Inhalation:
May cause respiratory tract irritation. Inhalation of vapors may
cause drowsiness and dizziness.
Chronic:
Not available.
Section 4 - First Aid Measures
|
Eyes:
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. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes.
Ingestion:
If victim is conscious and alert, give 2-4 cupfuls of milk or water.
Never give anything by mouth to an unconscious person. Possible
aspiration hazard. Get medical aid immediately.
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. Use water spray to keep fire-exposed containers
cool. 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 foam, dry chemical, or carbon dioxide.
Flash Point: -29 deg C ( -20.20 deg F)
Autoignition Temperature: 420 deg C ( 788.00 deg F)
Explosion Limits, Lower:1.20 vol %
Upper: 7.00 vol %
NFPA Rating:
(estimated) Health: ; Flammability: 3; Instability:
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. Provide ventilation.
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Remove contaminated clothing and
wash before reuse. Ground and bond containers when transferring
material. Use spark-proof tools and explosion proof equipment. Avoid
contact with eyes, skin, and clothing. Empty containers retain
product residue, (liquid and/or vapor), and can be dangerous. Take
precautionary measures against static discharges. Keep away from
heat, sparks and flame. Avoid ingestion and inhalation. Do not
pressurize, cut, weld, braze, solder, drill, grind, or expose empty
containers to heat, sparks or open flames. Use only with adequate
ventilation.
Storage:
Keep away from sources of ignition. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances. Flammables-area.
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.
Ventilation fans and other electrical service must be non-sparking
and have an explosion-proof design.
