Who are certified handlers?

Certified handlers are individuals specifically trained to handle opened pesticide containers, ensuring that safety protocols are followed while managing potentially hazardous materials. This includes understanding the risks associated with pesticides, proper handling techniques, and the importance of protective equipment. By functioning under supervision, certified handlers are better equipped to mitigate the risks involved in working with pesticides, which are regulated substances due to their potential impact on human health and the environment.

The other choices relate to different roles connected to pesticides but do not align with the specific definition of certified handlers. For instance, selling pesticides involves different qualifications and responsibilities, and while scientists may research pesticides, they may not necessarily handle them directly. Similarly, trainers for pesticide applicators focus on educating others rather than directly handling the substances themselves. Thus, the role of certified handlers is distinct, highlighting their importance in ensuring safe and compliant practices in the use of pesticides.
