First Aid Measures

Ingestion

Never give anything by mouth to an unconscious person. Get medical aid immediately. Do NOT induce vomiting. If conscious and alert, rinse mouth and drink 2-4 cupfuls of milk or water.

Inhalation

Remove from exposure to fresh air immediately. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid.

Skin

Get medical aid. Flush skin with plenty of soap and water for at least 15 minutes while removing contaminated clothing and shoes.

Eyes

Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid immediately.

Handling and Storage

Storage

Keep containers tightly closed. Do not expose to air. Store protected from light. Store under an inert atmosphere. Store in a cool, dry area away from incompatible substances.

Handling

Wash thoroughly after handling. Use with adequate ventilation. Do not get in eyes, on skin, or on clothing. Do not ingest or inhale. Store protected from light. Handle under an inert atmosphere. Store protected from air. Do not breathe vapors.

Hazards Identification

Inhalation

May be harmful if inhaled. Inhalation of aniline causes anoxia due to the formation of methemoglobinemia.

Skin

May cause skin irritation.

Eyes

May cause eye irritation. May cause chemical conjunctivitis.

Ingestion

May be harmful if swallowed. May form methemoglobin which in sufficient concentration causes cyanosis.

Hazards

When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards.

Exposure Controls/Personal Protection

Personal Protection

Eyes: Wear appropriate protective eyeglasses or chemical safety goggles as described by OSHA's eye and face protection regulations in 29 CFR 1910.133 or European Standard EN166. Skin: Wear appropriate protective gloves and clothing to prevent skin exposure. Clothing: Wear appropriate protective clothing to prevent skin exposure.

Respirators

A respiratory protection program that meets OSHA's 29 CFR 1910.134 and ANSI Z88.2 requirements or European Standard EN 149 must be followed whenever workplace conditions warrant a respirator's use.

Exposure Effects

Effects may be delayed.

Fire Fighting Measures

Flash Point

>110

Fire Fighting

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. To extinguish fire, use water, dry chemical, chemical foam, or alcohol-resistant foam.

Fire Potential

This chemical is probably combustible.

Accidental Release Measures

Small spills/leaks

Absorb spill using an absorbent, non-combustible material such as earth, sand, or vermiculite. Provide ventilation. Place under an inert atmosphere.

Stability and Reactivity

Incompatibilities

Air, acid anhydrides, acid chlorides, acids, chloroformates, direct light, strong oxidizing agents.

Stability

Stable under normal temperatures and pressures.

Decomposition

Nitrogen oxides, carbon monoxide, carbon dioxide.

Combustion Products

Fire may produce irritating, corrosive and/or toxic gases.
