Section 3 - Hazards Identification
EMERGENCY OVERVIEW
Appearance: clear yellow liquid. Flash Point: 85 deg C.
Warning! Harmful if inhaled. May cause eye and skin irritation. May cause
respiratory and digestive tract irritation. Potential cancer hazard. May cause
methemoglobinemia. Dangerous for the environment.
Target Organs: Blood.
Potential Health Effects
Eye: May cause eye irritation. The toxicological properties of this material have not
been fully investigated.
Skin: May cause skin irritation. The toxicological properties of this material have not
been fully investigated.
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. The toxicological properties of
this substance have not been fully investigated. 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 colored blood.
Inhalation: May cause respiratory tract irritation. The toxicological properties of this
substance have not been fully investigated. 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.
Section 4 - First Aid Measures
Eyes: 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.
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.
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 agent most appropriate to extinguish fire. Cool
containers with flooding quantities of water until well after fire is out. Use water
spray, dry chemical, carbon dioxide, or appropriate foam.

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. Clean up spills immediately, observing precautions in the Protective
Equipment section. Remove all sources of ignition. Provide ventilation.
Section 7 - Handling and Storage
Handling: Wash thoroughly after handling. Use with adequate ventilation. Avoid
contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion
and inhalation.
Storage: 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: Use adequate ventilation to keep airborne concentrations
low.
