Hazard Classes and CategoriesSkin Irrit. 2 (90.7%)Acute toxicity (ingestion) - category 4
BrandbekämpfungsverfahrenIf material on fire or involved in fire: Extinguish fire using agent suitable for type of surrounding fire. (Material itself does not burn or burns with difficulty.) Use water in flooding quantities as fog. Use foam, dry chemical, or carbon dioxide. Keep run-off water out of sewers and water sources. /Aminophenols/
EntsorgungsverfahrenSRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.
Preventive MeasuresIf material not on fire and not involved in fire: Keep sparks, flames, and other sources of ignition away. Keep material out of water sources and sewers. /Aminophenols/Personnel protection: Avoid breathing dusts, and fumes from burning material. Keep upwind. ... Avoid bodily contact with the material. ... Do not handle broken packages unless wearing appropriate personal protective equipment. /Aminophenols/
Personal Protective Equipment (PPE)Personnel protection: ... Wear positive pressure self-contained breathing apparatus. ... Wear appropriate chemical protective clothing. /Aminophenols/
Unerwünschte WirkungenMethemoglobinemia - The presence of increased methemoglobin in the bloodthe compound is classified as secondary toxic effect
Human Toxicity ExcerptsMAY CAUSE SKIN SENSITIZATION, DERMATITIS. INHALATION CAN CAUSE ASTHMA, METHEMOGLOBIN FORMATION. /P-AMINOPHENOL/

Antidote and Emergency Treatment9. IF...SPILLED ON CLOTHING, REMOVE IMMEDIATELY & DISCARD. ANY CONTAMINATED AREA OF SKIN SHOULD BE WASHED FOR 10 TO 15 MIN WITH SOAP & RUNNING WATER. ... /ANILINE//SRP:/ Basic treatment: Establish a patent airway. Suction if necessary. Watch for signs of respiratory insufficiency and assist ventilations if necessary. Administer oxygen by nonrebreather mask at 10 to 15 L/min. Monitor for shock and treat if necessary ... . Anticipate seizures and treat if necessary ... . For eye contamination, flush eyes immediately with water. Irrigate each eye continuously with normal saline during transport ... . Do not use emetics. For ingestion, rinse mouth and administer 5 ml/kg up to 200 ml of water for dilution if the patent can swallow, has a strong gag reflex, and does not drool. Administer activated charcoal ... . /Aniline and related compounds//SRP:/ Advanced treatment: Consider orotracheal or nasotracheal intubation for airway control in the patient who is unconscious. Monitor cardiac rhythm and treat arrhythmias as necessary ... . Start an IV with D5W /SRP: "To keep open", minimal flow rate/. Use lactated Ringer's if signs of hypovolemia are present. Watch for signs of fluid overload. Administer 1% solution methylene blue if patient is symptomatic with severe hypoxia, cyanosis, and cardiac compromise not responding to oxygen. ... . For hypotension with signs of hypovolemia, administer fluid cautiously. Consider vasopressors if hypotensive with a normal fluid volume. Watch for signs of fluid overload ... .
