Section 3 - Hazards Identification

EMERGENCY OVERVIEW
Appearance: clear yellow liquid. Flash Point: 63 deg C.
Danger! Toxic if swallowed, inhaled or absorbed
through the skin. Causes eye, skin, and respiratory tract
irritation. Questionable carcinogen. Combustible liquid and
vapor. May cause methemoglobinemia.
Target Organs: Blood, kidneys, central nervous
system, liver, spleen, respiratory system, eyes, skin.
Potential Health Effects
Eye:
Causes eye irritation. May result in corneal injury.
Skin:
Causes skin irritation. May cause dermatitis. Toxic in contact with
skin.
No skin sensitization reported in a test on guinea pigs.
Ingestion:
May cause irritation of the digestive tract. May cause
methemoglobinemia, cyanosis (bluish discoloration of skin due to
deficient oxygenation of the blood), convulsions, and death. May
cause nausea and vomiting. May cause central nervous system
depression. Toxic if swallowed.
Inhalation:
Causes respiratory tract irritation. May cause methemoglobinemia,
cyanosis (bluish discoloration of skin due to deficient oxygenation
of the blood), convulsions, tachycardia, dyspnea (labored
breathing), and death. Toxic if inhaled. Overexposure produces
central nervous system depression.
Chronic:
May cause liver and kidney damage. May cause methemoglobinemia,
which is characterized by chocolate-brown colored blood, headache,
weakness, dizziness, breath shortness, cyanosis (bluish skin due to
deficient oxygenation of blood), rapid heart rate, unconsciousness
and possible death. Repeated exposure may cause damage to the
spleen. Laboratory experiments have resulted in mutagenic effects.
Chronic exposure may cause blood effects. Animal studies have
reported the development of tumors. Limited evidence of a
carcinogenic effect.
Repeated exposures may cause red blood cell destruction, or abnormal
blood forming system function with anemia. Lifelong exposure
increased the number of spleen tumors in male rats and stomach tumors
in female mice.

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 imme
diately.
Skin:
Get medical aid immediately. Immediately flush skin with plenty of
water for at least 15 minutes while removing contaminated clothing
and shoes.
Ingestion:
POISON material. If swallowed, get medical aid immediately. Only
induce vomiting if directed to do so by medical personnel. Never give
anything by mouth to an unconscious person.
Inhalation:
Get medical aid immediately. Remove from exposure and move to fresh
air immediately. If breathing is difficult, give oxygen. Do not use
mouth-to-mouth resuscitation if victim ingested or inhaled the
substance; induce artificial respiration with the aid of a pocket
mask equipped with a one-way valve or other proper respiratory
medical device.
Notes to Physician:
Treat symptomatically and supportively.
|
Section 5 - Fire Fighting Measures
|

pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Will burn if involved in a fire. Containers may
explode in the heat of a fire. Combustible liquid and vapor.
Extinguishing Media:
Use water spray to cool fire-exposed containers. Use foam, dry
chemical, or carbon dioxide. Water may be ineffective.

(estimated) Health: 3; Flammability: 2; Instability: 1
|
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. Wear a self contained breathing
apparatus and appropriate personal protection. (See Exposure
Controls, Personal Protection section). 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 spark-proof tools and explosion proof equipment. Do not get in
eyes, on skin, or on clothing. Take precautionary measures against
static discharges. Keep away from heat, sparks and flame. Do not
ingest or inhale. Use only in a chemical fume hood.
Storage:
Keep away from sources of ignition. Store in a cool, dry place.
Store in a tightly closed container. Store protected from light and
air.
|
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 only under a chemical fume hood.

No information available.
Environmental:
Terrestrial: May be susceptible to moderate to high leaching in soil.
Aquatic: The persistence half-life of N,N-dimethylaniline in the
Rhine River has been estimated to be 2.3 days based on the observed
decrease in concn over a monitored river length. Atmospheric:
Expected to exist almost entirely in the gas-phase in the ambient
atmosphere. Gas-phase N,N- dimethylaniline is expected to degrade
rapidly in air by reaction with photochemically produced hydroxyl
radicals and by reaction with ozone; the half-lives for these
reactions in an average atmosphere to be up to 30 hours.
Physical:
Expected to biodegrade but not bioconcentrate.
Other:
Do not empty into drains.
