If a pesticide label states that you must wear gloves based on guidelines in Chemical Resistance Category "D", which materials provide the best protection from the pesticide?

When a pesticide label specifies that gloves must be worn according to guidelines in Chemical Resistance Category "D," it indicates that the pesticide can potentially break through certain materials. Gloves made from barrier laminate or butyl rubber provide superior protection in this context.

Barrier laminate is a multi-layer material specifically designed to resist permeation and degradation by various chemicals, making it ideal for handling pesticides. Butyl rubber also offers excellent resistance to permeation by organic chemicals and is especially noted for its low permeability to gas and vapor, further reducing the risk of chemical exposure during application.

Using gloves made from these materials ensures that the applicator has a high level of protection against potential skin contact with hazardous pesticides, which is critical for safety in handling chemicals. Other materials mentioned may not provide the same level of chemical resistance, which limits their effectiveness for protection in situations where exposure to dangerous substances is a risk.
