| First Aid Measures | Back to Contents | 【Ingestion】
If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid immediately. | 【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 | Back to Contents | 【Storage】
Store in a cool, dry, well-ventilated area away from incompatible substances. Poison room locked. Keep containers tightly closed. | 【Handling】
Wash thoroughly after handling. Use only in a well ventilated area. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Keep container tightly closed. Avoid ingestion and inhalation. |
| Hazards Identification | Back to Contents | 【Inhalation】
Dust is irritating to the respiratory tract. | 【Skin】
Causes skin irritation. | 【Eyes】
Dust may cause mechanical irritation. | 【Ingestion】
May be harmful if swallowed. Causes digestive tract irritation. | 【Hazards】

| 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】
Follow the OSHA respirator regulations found in 29CFR 1910.134 or European Standard EN 149. Always use a NIOSH or European Standard EN 149 approved respirator when necessary. | 【Exposure Effects】
Acute poisoning may cause rapid heart rate and rapid breathing. Severe headache, CNS disturbances, and tremor may occur. A high incidence of gynecological disorders and excess frequency of spontaneous abortions have been noted. The fetal liver can n-oxygenate aniline to form phenylhydroxylamine. Fetal effects include higher levels of methemoglobin those found in than the mother. Fetal poisoning may occur. <br>No data were available to assess the potential effects of exposure to aniline during lactation. <br>No information about possible male reproductive effects was found in available references at the time of this review | 【Exposure limit(s)】
NIOSH: Potential Occupational Carcinogen. |
| Fire Fighting Measures | Back to Contents | 【Flash Point】
126 | 【Autoignition】
521 | 【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. May polymerize explosively when involved in a fire. Contact with metals may evolve flammable hydrogen gas. Containers may explode when heated. Combustible material; may burn but does not ignite readily. Extinguishing media: Cool containers with flooding quantities of water until well after fire is out. In case of fire, use water spray, dry chemical, carbon dioxide, or alcohol-resistant foam. | 【Upper exp. limit】
9.8 | 【Lower exp. limit】
1.5 | 【Fire Potential】
Slightly flammable. Flammable at elevated temperatures - moderate hazard. |
| Accidental Release Measures | Back to Contents | 【Small spills/leaks】
Absorb spill with inert material, (e.g., dry sand or earth), then place into a chemical waste container. Avoid runoff into storm sewers and ditches which lead to waterways. Avoid generating dusty conditions. Remove all sources of ignition. Provide ventilation. |
| Stability and Reactivity | Back to Contents | 【Disposal Code】
9 | 【Incompatibilities】
Acids - acid chlorides - acid anhydrides - chloroformates - strong oxidizing agents. | 【Stability】
Stable under normal temperatures and pressures. | 【Decomposition】
Nitrogen oxides, carbon monoxide, carbon dioxide, nitrogen. | 【Combustion Products】
Toxic oxides of nitrogen may form in fire. |
