**** SECTION 3 - HAZARDS IDENTIFICATION ****
EMERGENCY OVERVIEW
Toxic by inhalation, in contact with skin and if swallowed. Limited
evidence of a carcinogenic effect. Toxic to aquatic organisms, may
cause long-term adverse effects in the aquatic environment.
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.
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.
**** SECTION 4 - FIRST AID MEASURES ****
Eyes:
In case of contact, immediately flush eyes with plenty of water for
at 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.
**** 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.
