First Aid Measures | Back to Contents | 【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 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. Wash clothing before reuse. | 【Eyes】
Immediately flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Get medical aid. |
Handling and Storage | Back to Contents | 【Storage】
Store in a tightly closed container. Store in a cool, dry, well-ventilated area away from incompatible substances. | 【Handling】
Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Use only in a well ventilated area. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation. |
Hazards Identification | Back to Contents | 【Inhalation】
May cause respiratory tract irritation. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate and chocolate-brown blood. Inhalation of aniline causes anoxia due to the formation of methemoglobinemia. | 【Skin】
May cause skin irritation. Absorption into the body may cause cyanosis. | 【Eyes】
May cause eye irritation. May cause chemical conjunctivitis and corneal damage. | 【Ingestion】
May cause irritation of the digestive tract. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate and chocolate-brown colored blood. Overexposure may cause methemoglobinemia. | 【Hazards】
When heated, vapors may form explosive mixtures with air: indoors, outdoors, and sewers explosion hazards. | 【EC Risk Phrase】

Exposure Controls/Personal Protection | Back to Contents | 【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 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】
May cause methemoglobinemia, which is characterized by chocolate-brown colored blood, headache, weakness, dizziness, breath shortness, cyanosis, rapid heart rate, unconsciousness and possible death. |
Fire Fighting Measures | Back to Contents | 【Flash Point】
139 | 【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 spray, dry chemical, carbon dioxide, or appropriate foam. | 【Fire Potential】
Combustible material: may burn but does not ignite readily. |
Stability and Reactivity | Back to Contents | 【Incompatibilities】
Acid anhydrides, acid chlorides, acids, chloroformates, strong oxidizing agents. | 【Stability】
Stable under normal temperatures and pressures. | 【Decomposition】
Nitrogen oxides, carbon monoxide, irritating and toxic fumes and gases, carbon dioxide, nitrogen, ammonia. | 【Combustion Products】
Fire may produce irritating, corrosive and/or toxic gases. |
