EMERGENCY OVERVIEW
Appearance: clear, colorless liquid. Flash Point: 157 deg F.
Warning! Causes respiratory tract irritation.
Irritant. Causes eye and skin irritation. May be absorbed through
intact skin. Combustible liquid and vapor.
May be harmful if swallowed. May cause digestive tract irritation.
May cause central nervous system depression. Moisture sensitive.
Target Organs: Central nervous system.
Potential Health Effects
Eye:
Causes eye irritation. May cause chemical conjunctivitis and
corneal damage.
Skin:
Causes skin irritation. May be absorbed through the skin in harmful
amounts. May cause irritation and dermatitis. May cause cyanosis of
the extremities.
Ingestion:
May cause gastrointestinal irritation with nausea, vomiting and
diarrhea. May be harmful if swallowed.
Inhalation:
Causes respiratory tract irritation. Aspiration may lead to
pulmonary edema. Can produce delayed pulmonary edema. Inhalation at
high concentrations may cause CNS depression and asphixiation.
Chronic:
Effects may be delayed.
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. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
before reuse.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
drink 2-4 cupfuls of milk or water.
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. Do NOT use mouth-to-mouth
resuscitation.
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. During a fire, irritating and highly toxic gases
may be generated by thermal decomposition or combustion. Use water
spray to keep fire-exposed containers cool. Combustible liquid.
Vapors may be heavier than air. They can spread along the ground and
collect in low or confined areas. Containers may explode when heated.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Do NOT get water
inside containers. Use water spray, dry chemical, carbon dioxide, or
appropriate foam.
Flash Point: 157e deg F ( 69.44 deg C)
Autoignition Temperature: Not applicable.
Explosion Limits, Lower:Not available.
Upper: Not available.
NFPA Rating:
(estimated) Health: 2; Flammability: 2; 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. Clean up spills immediately,
observing precautions in the Protective Equipment section. Scoop up
with a nonsparking tool, then place into a suitable container for
disposal. Remove all sources of ignition. Provide ventilation. Do not
get water inside containers.
Section 7 - Handling and Storage
|
Handling:
Wash hands before eating. Remove contaminated clothing and wash
before reuse. Use only in a well-ventilated area. Avoid contact with
eyes, skin, and clothing. 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. Do not allow contact with water. Wash clothing before
reuse. Do not pressurize, cut, weld, braze, solder, drill, grind, or
expose empty containers to heat, sparks or open flames. Keep from
contact with moist air and steam.
Storage:
Keep away from heat, sparks, and flame. Keep away from sources of
ignition. Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Keep
refrigerated. (Store below 4°C/39°F.) Store protected from moisture.
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
ventilation to keep airborne concentrations low.
