Which of the following describes a closed mixing and loading system?

A closed mixing and loading system is specifically designed to minimize the risk of handler exposure to pesticides during the mixing and loading process. This type of system integrates features that contain chemicals within a secured environment, ensuring that operators do not come into direct contact with the pesticides.

This design is important for reducing hazards associated with pesticide application, as it helps to prevent splashes, spills, and inhalation of toxic substances, thereby enhancing the safety of the applicator. The system typically includes sealed containers and specialized equipment that allows for transfer and mixing without opening the system to the atmosphere, thereby limiting exposure risks.

In contrast, other options imply that the system either allows for exposure (like open containers), lacks regulations, or operates without safety measures, which are not characteristics of a closed mixing and loading system.
