  • 2. GHS Label Elements
    • Pictograms:
      • Skull and Crossbones (GHS06)
      • Health Hazard (GHS08)
      • Environment (GHS09)
    • Signal Word: Danger
    • Hazard Statements (H-Statements):
      • H301 + H311 + H331: Toxic if swallowed, in contact with skin or if inhaled.
      • H351: Suspected of causing cancer.
      • H373: May cause damage to organs (blood) through prolonged or repeated exposure.
      • H410: Very toxic to aquatic life with long-lasting effects.
    • Precautionary Statements (P-Statements):
    • Prevention:
      • P201: Obtain special instructions before use.
      • P273: Avoid release to the environment.

  • 3. Summary of Primary Hazards
    • Health Hazards: Toxic by all routes of exposure (ingestion, inhalation, and skin absorption). Suspected of causing cancer. A primary hazard is the formation of methemoglobin, which reduces the oxygen-carrying capacity of the blood, leading to cyanosis (bluish skin), confusion, and headache.
    • Environmental Hazards: Very toxic to aquatic life with long-lasting effects. It is critical to prevent its release into the environment.
    • Fire Hazards: Combustible solid. Emits toxic and corrosive fumes under fire conditions.
