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?

The correct choice is based on the understanding of the effectiveness of materials in providing protection against pesticides categorized under Chemical Resistance Category "D." This category generally indicates substances that can pose moderate risk to personnel and may require specific protective measures.

Barrier laminate and butyl rubber are both highly effective at protecting against many types of chemicals, including pesticides. Barrier laminates are composites designed specifically to resist permeation by hazardous substances, making them an excellent choice for situations where there's a risk of chemical exposure. Butyl rubber, on the other hand, is known for its exceptional resistance to a wide variety of chemicals and solvents, particularly those that are organic in nature.

Choosing this option reflects a solid understanding of the materials that would best shield users from potential harm while handling pesticides, ensuring safety and compliance with the labeling requirements.
