Why are weighing, measuring, mixing, and filling considered more hazardous to the applicator than spraying?

Weighing, measuring, mixing, and filling are considered more hazardous to the applicator because these activities typically involve handling pesticides in their concentrated forms. During these processes, the applicator is at greater risk of direct exposure to higher concentrations of active ingredients, which can be more toxic and harmful than exposure to diluted products during the actual spraying phase. Concentrated pesticides are often more volatile and can create a greater risk of inhalation or dermal exposure through spills or splashes.

While applying pesticides through spraying may involve other risks, such as drift or contamination of non-target areas, the handling of concentrated formulations presents a heightened danger of immediate and severe exposure. Therefore, it is crucial for applicators to exercise extreme caution, wear appropriate personal protective equipment, and follow strict protocols during these initial stages of pesticide use to mitigate the risk of harm.
