Which materials provide the best protection from pesticides when the label references Chemical Resistance Category 'D'?

• A. Nitrile rubber.
• B. Barrier laminate or butyl rubber.
• C. Latex.
• D. Vinyl.

Answer: (B)

Chemical resistance categories on pesticide labels indicate how well a material resists permeation by the chemical. Category D represents the highest level of resistance shown on the label for that pesticide, meaning it offers the strongest protection among the listed options when handling that product. Barrier laminate or butyl rubber gloves provide the best protection because they are designed to resist a wide range of aggressive chemicals and permeation. Barrier laminates are multi-layer materials that create a robust chemical barrier, while butyl rubber combines low permeability with strong chemical resistance, making it less likely for pesticides to penetrate over typical exposure times. In contrast, latex and vinyl are more prone to degradation or permeation by many pesticides, and nitrile, though protective, may not meet the highest resistance required by Category D for certain products. So, if the label specifies Category D, choose barrier laminate or butyl rubber gloves, ensure a proper fit, and replace them if they become damaged or contaminated.
