  • 1. GHS Classification
    • Acute Toxicity, Oral (Category 3)
    • Acute Toxicity, Dermal (Category 3)
    • Acute Toxicity, Inhalation (Category 3)
    • Specific Target Organ Toxicity — Repeated Exposure (Category 2) (Affects blood)
    • Hazardous to the Aquatic Environment, Acute Hazard (Category 1)
    • Hazardous to the Aquatic Environment, Chronic Hazard (Category 1)
  • 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.
      • 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:
      • P260: Do not breathe dust/fume/gas/mist/vapors/spray.
      • P273: Avoid release to the environment.
      • P280: Wear protective gloves, protective clothing, eye protection, and face protection.
    • Response:
      • P301 + P310: IF SWALLOWED: Immediately call a POISON CENTER or doctor/physician.
      • P302 + P352 + P312: IF ON SKIN: Wash with plenty of soap and water. Call a POISON CENTER or doctor/physician if you feel unwell.
      • P304 + P340 + P311: IF INHALED: Remove person to fresh air and keep comfortable for breathing. Call a POISON CENTER or doctor/physician.
      • P314: Get medical advice/attention if you feel unwell.
      • P391: Collect spillage.
    • Storage:
      • P405: Store locked up.
    • Disposal:
      • P501: Dispose of contents/container to an approved hazardous waste disposal plant.
  • 3. Summary of Primary Hazards
    • Health Hazards: Toxic by ingestion, inhalation, and skin absorption. The main effect of exposure is the formation of methemoglobin in the blood, which impairs the blood's ability to carry oxygen. This can cause cyanosis (a blue discoloration of the skin and lips), confusion, headache, and dizziness.
    • Environmental Hazards: Very toxic to aquatic life with long-lasting effects. It is critical to prevent its release into drains, soil, or waterways.
    • Fire Hazards: Combustible liquid. Emits toxic and irritating fumes of nitrogen oxides and carbon monoxide when heated to decomposition.
