Which statement is true about PPE chemical resistance?

Which statement is true about PPE chemical resistance?

• A. The ability of a given material to protect an individual from a pesticide product is largely a function of the type of solvent used to formulate the pesticide product
• B. Cloth is easy to clean after it becomes contaminated with a pesticide, or it can be inexpensively disposed of after each use
• C. Cotton, leather, and canvas are chemically resistant to dry formulations
• D. All of the above

Answer: (A)

PPE chemical resistance depends on chemical compatibility between the protective material and the pesticide formulation, especially the solvent. The ability of a given material to protect a person from a pesticide is largely determined by the solvent and other chemical constituents in the product, because the solvent interacts with, and can soften or permeate, the protective material. This means selecting PPE requires looking at the product’s formulation and the material’s compatibility data, rather than assuming a garment is inherently protective just because it’s fabric. Cloth isn’t reliably easy to clean after contamination, and disposing of contaminated cloth isn’t inexpensive or risk-free, which undermines its usefulness as protective gear for pesticide exposure. Cotton, leather, and canvas aren’t broadly and reliably chemically resistant to dry formulations, either, since different pesticides and carriers can degrade or allow permeation through those materials. Because of these issues, the statement about solvent-based compatibility best captures how protection works, while the other points don’t generally hold.
