When is it mandatory to use a Closed System when handling pesticides?

Using a Closed System when handling pesticides is specifically mandated when dealing with Minimal Exposure Pesticides or if the product label explicitly requires it. A Closed System is designed to reduce the risk of exposure to both the applicator and the environment by minimizing the potential for spills, splashes, or vapor release during the handling process. When a pesticide is classified as Minimal Exposure, it indicates that extra precautions are necessary to protect workers from potential harm, thus making the use of a Closed System essential in these circumstances.

In addition, following the specific instructions on a pesticide label is crucial because it provides detailed information on how to handle the product safely. Labels often include requirements for protective equipment and application methods, and any mention of a Closed System directly indicates the importance of using such technology to ensure safety. Thus, the reliance on a Closed System in these scenarios is rooted in safety regulations designed to protect both human health and the environment during pesticide handling.
