What is the primary purpose of a closed transfer system when handling pesticides?

• A. To speed up the mixing process.
• B. To minimize operator exposure and reduce drift during mixing and loading.
• C. To improve application color.
• D. To eliminate the need for PPE.

Answer: (B)

A closed transfer system is designed to protect people and the environment during handling by keeping the pesticide sealed as it moves from the container to the mixing or loading equipment. This containment reduces skin contact, inhalation risk, and accidental spills, and it also limits drift by preventing vapors or droplets from escaping during transfer. That direct focus on reducing exposure and drift during mixing and loading is what makes this approach the correct answer. It isn’t about speeding up the process or changing the product’s appearance, and PPE is still needed even with a closed system, so it doesn’t eliminate that requirement.
