PPE chemical resistance is primarily influenced by which factor?

• A. Temperature of storage
• B. Color of the PPE
• C. Brand of the PPE
• D. Solvent type

Answer: (D)

PPE chemical resistance comes from chemical compatibility between the PPE material and the solvent or chemical it will contact. Different materials resist solvents in different ways because their molecular structure, polarity, and how easily the solvent can permeate or swell the material determine resistance. The specific solvent, along with its concentration and how long exposure lasts, is the main factor in whether the PPE will protect you effectively. Color, brand, or storage temperature don’t change the inherent compatibility of the material with the chemical. For reliable selection, refer to the material’s compatibility data and consider the actual exposure conditions.
