MDARD Michigan Core Pesticide Applicator Practice Exam

What part of a pesticide formulation primarily determines the type of gloves needed?

1. Active ingredient

2. Surfactants

3. Solvents

4. Preservatives

The correct answer is: Solvents

The type of gloves needed when handling a pesticide formulation is primarily influenced by the solvents present in that formulation. Solvents can vary in their chemical composition and properties, which can affect the permeability of glove materials. Some solvents can quickly penetrate certain glove materials, while others may be more resistant. Understanding the solvent characteristics is crucial because they can determine the level of protection required. For instance, if the solvent has a high potential for permeation through a specific glove material, it might necessitate the use of thicker gloves made from tougher materials, or specialized chemical-resistant gloves designed to withstand those specific solvents. While active ingredients, surfactants, and preservatives play important roles in the function and stability of the pesticide, it is the solvents that primarily dictate the protective equipment used during handling. Proper glove selection based on the solvent types within a formulation is essential for ensuring safety and minimizing the risk of dermal exposure.
