During which phase is applicator exposure to pesticides most likely to occur?

Applicator exposure to pesticides is most likely to occur through dermal exposure during the mixing and spraying phase. This is the period when an applicator is handling the concentrated pesticide formulations and applying them to the target area. During mixing, the risk comes from splashes or spills that can contact the skin or clothing. During spraying, there's potential for drift or direct contact with the pesticide solution, which can also lead to skin absorption.

This phase demands careful handling techniques, personal protective equipment (PPE), and knowledge of safe application practices to minimize exposure. While exposure can occur at other times, such as during disposal, eating, or storage, those situations typically present a lower risk compared to the direct handling of the pesticides involved during active application.
