  • 2.1. GHS Classification
    • Acute Toxicity, Oral (Category 4)
    • Acute Toxicity, Dermal (Category 4)
    • Acute Toxicity, Inhalation (Category 4)
    • Skin Irritation (Category 2)
    • Eye Irritation (Category 2A)
    • Hazardous to the Aquatic Environment, Chronic Hazard (Category 2)
  • 2.2. GHS Label Elements
    • Pictogram: Exclamation Mark (GHS07), Environment (GHS09)
  • Signal Word: Warning
  • Hazard Statements (H-Statements):
    • H302 + H312 + H332: Harmful if swallowed, in contact with skin, or if inhaled.
    • H315: Causes skin irritation.
    • H319: Causes serious eye irritation.
    • H411: Toxic to aquatic life with long-lasting effects.
  • Precautionary Statements (P-Statements):
    • Prevention:
      • P261: Avoid breathing dust/fume/gas/mist/vapors/spray.
      • P273: Avoid release to the environment.
      • P280: Wear protective gloves, protective clothing, eye protection, and face protection.
    • Response:
      • P302 + P352: IF ON SKIN: Wash with plenty of soap and water.

  • 2.3. Summary of Primary Hazards
    • Health Hazards: Harmful by all primary routes of exposure. It can cause irritation to the skin and eyes. Like many aromatic amines, it should be handled with care to avoid absorption through the skin, which can lead to methemoglobinemia (interference with blood oxygen transport).
    • Fire Hazards: Combustible. During a fire, irritating and highly toxic gases may be generated.
    • Environmental Hazards: Toxic to aquatic organisms. Prevent the substance from entering drains, sewers, or watercourses.
