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.

Skin
Get medical aid immediately. 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 immediately.

Storage
Keep container closed when not in use. Store in a cool, dry, well-ventilated area away from incompatible substances.

Handling
Wash hands before eating. Use only in a well ventilated area. Minimize dust generation and accumulation. Avoid contact with eyes, skin, and clothing. Avoid ingestion and inhalation. Wash clothing before reuse.

Inhalation
Causes respiratory tract irritation. May cause methemoglobinemia, cyanosis, convulsions, tachycardia, dyspnea, and death. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate and chocolate-brown blood.

Skin
Causes skin irritation.

Eyes
Causes eye irritation.

Ingestion
Harmful if swallowed. May cause gastrointestinal irritation with nausea, vomiting and diarrhea. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate and chocolate-brown colored blood. Ingestion of nitrate containing compounds can lead to methemoglobinemia.

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

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
