Section 12: Ecological Information (Score: D – Major Weakness)

• Statement: “No data available” for most parameters. Typical for 2021 industrial SDS.
• Expected toxicity (based on similar corrosion inhibitors): Likely harmful to aquatic life (high pH alone is toxic to fish/invertebrates).
• Missing: Bioaccumulation, persistence, degradation half-life, NOEC/LC50 values.
• Verdict: Unacceptable for environmental compliance purposes. Users must request supplemental ecotoxicity data.

Section 9: Physical & Chemical Properties (Score: C)

• Typical values:
  • Extinguishing Media: Water, foam, dry chemical, or carbon dioxide.
  • Special Fire-Fighting Procedures: Wear self-contained breathing apparatus.
