What is considered the most dangerous time when handling pesticides?

Pouring chemicals into the tank is indeed regarded as one of the most dangerous times for handling pesticides due to the high risk of exposure to concentrated chemicals. During this process, there is a greater likelihood of splashes or spills, which can lead to direct contact with the skin or accidental inhalation of harmful vapors. Additionally, pouring requires careful handling, and improper pouring techniques can exacerbate these risks.

While mixing with water and calibrating the sprayer also present risks, they generally have established safety practices to minimize exposure. Applying pesticides in windy conditions is certainly hazardous, as it can result in drift, which poses risks not only to the applicator but also to nearby populations and non-target areas. However, the act of pouring the concentrated chemicals presents a significant immediate danger due to the potential for exposure right at the source before any further dilution or application occurs.
