EMERGENCY OVERVIEW
Appearance: colorless liquid.
Light sensitive. May cause central nervous system effects. Causes
severe eye and skin irritation. Causes respiratory tract irritation.
May cause digestive tract irritation. May cause cancer based on
animal studies. Harmful if swallowed. Warning!
Target Organs: Central nervous system.
Potential Health Effects
Eye:
Causes eye irritation. Causes redness and pain. If splashed in
the eye, causes conjunctivitis.
Skin:
Causes skin irritation. May cause irritation with pain and stinging,
especially if the skin is abraded. May cause reddening of the skin.
Ingestion:
Harmful if swallowed. Aspiration hazard. May cause irritation of the
digestive tract. May cause effects similar to those for inhalation
exposure.
Prolonged or repeated exposure may cause CNS effects.
Inhalation:
Causes respiratory tract irritation. May cause lung damage. May
cause spleen and liver damage. Initial symptoms include lethargy,
drowsiness, slurred speech, ataxia, muscular incoordination, visual
disturbances. May progress to convulsions, coma and death. Other
symptoms include giddiness, diarrhea, sleepiness, irritability,
vomiting, pallor, muscular twitching and kidney effects.
Chronic:
Chronic inhalation may cause effects similar to those of acute
inhalation.

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
immediately.
Skin:
Get medical aid. Immediately flush skin with plenty of water for at
least 15 minutes while removing contaminated clothing and shoes.
Wash clothing before reuse.
Ingestion:
Do NOT induce vomiting. If victim is conscious and alert, give 2-4
cupfuls of milk or water. Never give anything by mouth to an
unconscious person. Get medical aid immediately.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If not breathing, give artificial respiration. If
breathing is difficult, give oxygen. 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. Substance is noncombustible. Decomposes at high
temperatures, resulting in toxic and corrosive products. Containers
may explode in the heat of a fire. Vapors may be heavier than air.
They can spread along the ground and collect in low or confined
areas.
Extinguishing Media:
Use extinguishing media most appropriate for the surrounding fire.
Do NOT get water inside containers. For small fires, use dry
chemical, carbon dioxide, or water spray. For large fires, use water
spray, fog or regular foam. Cool containers with flooding quantities
of water until well after fire is out.
Flash Point: 270 deg C ( 518.00 deg F)
Autoignition Temperature: 352 deg C ( 665.60 deg F)

|
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. Provide ventilation. Do not get
water inside containers.
|
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Do not breathe dust, vapor, mist, or
gas. Do not get in eyes, on skin, or on clothing. Do not ingest or
inhale. Store protected from light. Use only in a chemical fume
hood.
Storage:
Do not store in direct sunlight. Store in a tightly closed
container. Store in a cool, dry, well-ventilated area away from
incompatible substances.
|
Section 8 - Exposure Controls, Personal Protection
|
Engineering Controls:
Local exhaust ventilation may be necessary to control any air
contaminants to within their TLVs during the use of this product.
Use only under a chemical fume hood.
