What Class of Hazardous Material Is Glacial Acetic Acid

Glacial acetic acid, or acetic acid, is highly corrosive at elevated concentrations, leading to severe skin burns and blindness, and emits corrosive gases that pose significant threats to the respiratory tract. Notably, the level of harm acetic acid inflicts primarily hinges on its concentration.

Present guidelines indicate that it exhibits maximum corrosivity above 90% concentration. Concentrations ranging from 10%-25% are irritating, but any level above 25% mandates the use of protective gear. Thus, it’s apparent that glacial acetic acid is identified as a Class 8 hazardous substance.
