Oklahoma Service Technician Practice Exam

Closed mixing and loading systems are specifically designed to prevent pesticides from contacting handlers. These systems work by enclosing the mixing and loading process within a sealed environment, minimizing the opportunity for any direct exposure to pesticides. This greatly enhances safety for technicians who handle these substances, as it reduces the risk of skin contact and inhalation of pesticide fumes during application, mixing, or loading activities.

While other options mention important concerns in pesticide management, the primary focus of closed systems is handling safety for the operators involved in the mixing and loading phases. The design of these systems effectively mitigates risks associated with pesticide exposure directly to the handler, making it a vital tool in promoting safer practices within this sector.
