Section 3 - Hazards Identification

EMERGENCY OVERVIEW
Appearance: oily liquid. Flash Point: 63 deg C.
May be fatal if swallowed. Danger! Causes eye,
skin, and respiratory tract irritation. Harmful if absorbed through
skin or if inhaled. Combustible liquid and vapor.
Impairs the oxygen carrying capacity of the blood. Methemoglobin
former - can cause cyanosis. May cause central nervous system
depression.
Target Organs: Blood, kidneys, central nervous
system.
Potential Health Effects
Eye:
May cause severe eye irritation. May result in corneal injury.
Skin:
Causes skin irritation. May be absorbed through the skin in harmful
amounts.
No skin sensitization reported in a test on guinea pigs.
Ingestion:
May be fatal if swallowed. May cause methemoglobinemia, cyanosis
(bluish discoloration of skin due to deficient oxygenation of the
blood), convulsions, and death. May cause central nervous system
depression.
Inhalation:
Causes respiratory tract irritation. May cause effects similar to
those described for ingestion. Methemoglobinemia is characterized by
dizziness, drowsiness, headache, shortness of breath, cyanosis
(bluish discoloration of skin due to deficient oxygenation of the
blood), rapid heart rate and chocolate-brown blood. Inhalation of
aniline causes anoxia due to the formation of methemoglobin.
Chronic:
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.
Exposure to large doses may cause central nervous system depression.
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:
In case of contact, immediately flush eyes with plenty of water for a
t least 15 minutes. Get medical aid immediately.
Skin:
In case of contact, immediately flush skin with plenty of water for
at least 15 minutes while removing contaminated clothing and shoes.
Get medical aid immediately. Wash clothing before reuse.
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:
If inhaled, remove to fresh air. If not breathing, give artificial
respiration. If breathing is difficult, give oxygen. Get medical aid.
Notes to Physician:
For methemoglobinemia, administer oxygen alone or with Methylene
Blue depending on the methemoglobin concentration in the blood.
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. Water runoff can cause environmental damage. Dike
and collect water used to fight fire. 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.
Water may be ineffective. Material is lighter than water and a fire
may be spread by the use of water. Combustible liquid and vapor.
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:
Water may be ineffective. For small fires, use dry chemical, carbon
dioxide, or water spray. For large fires, use dry chemical, carbon
dioxide, alcohol-resistant foam, or water spray.
Flash Point: 63 deg C ( 145.40 deg F)
Autoignition Temperature: 371 deg C ( 699.80 deg F)
Explosion Limits, Lower:1.0%
Upper: 7.0%
NFPA Rating:
(estimated) Health: 3; 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. Avoid runoff into storm sewers and
ditches which lead to waterways. Remove all sources of ignition. Use
a spark-proof tool. Provide ventilation.
Section 7 - Handling and Storage
|
Handling:
Wash thoroughly after handling. Wash hands before eating. Remove
contaminated clothing and wash before reuse. Use with adequate
ventilation. Ground and bond containers when transferring material.
Do not get in eyes, on skin, or on clothing. Empty containers retain
product residue, (liquid and/or vapor), and can be dangerous. Do not
pressurize, cut, weld, braze, solder, drill, grind, or expose empty
containers to heat, sparks or open flames. Keep away from heat and
flame. Avoid breathing vapor or mist.
Storage:
Store in a tightly closed container. Store in a cool, dry,
well-ventilated area away from incompatible substances. Do not store
in metal containers. Store protected from light and air. Isolate
from oxidizing materials and acids.
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 general or
local exhaust ventilation to keep airborne concentrations below the
permissible exposure limits.

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:
No information available.
