Hazards Identification
Inhalation
Causes respiratory tract irritation. May cause liver and kidney damage. Methemoglobinemia is characterized by dizziness, drowsiness, headache, breath shortness, cyanosis with bluish skin, rapid heart rate and chocolate-brown blood. Can produce delayed pulmonary edema. Inhalation of aniline causes anoxia due to the formation of methemoglobinemia.

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.
