    • Health Hazards: Harmful through all primary routes of exposure (ingestion, skin contact, inhalation). Prolonged or repeated exposure can lead to the formation of methemoglobin, causing cyanosis (bluish discoloration of the skin). It is a suspected carcinogen and reproductive toxin, and can cause damage to target organs.
    • Environmental Hazards: Toxic to aquatic organisms and can cause long-term adverse effects in the aquatic environment.
    • Fire Hazards: Combustible liquid. Keep away from heat, sparks, and open flames.
