    • Health Hazards: Toxic through all primary routes of exposure (ingestion, skin contact, inhalation). Can be absorbed through the skin, causing symptoms similar to aniline poisoning. Exposure can lead to the formation of methemoglobin, resulting in cyanosis (bluish discoloration of the skin), headache, and dizziness. Suspected of causing cancer.
    • Environmental Hazards: Toxic to aquatic organisms and may cause long-term adverse effects in the aquatic environment.
    • Fire Hazards: Combustible solid. Dust may form an explosive mixture with air.
