What additional safety measure is recommended while mixing or loading pesticides?

When mixing or loading pesticides, wearing a chemical-resistant apron is crucial as it provides a barrier between the pesticide and your skin. Pesticides can pose significant health risks through dermal exposure, and an apron made from materials designed to resist chemicals can help prevent accidental spills or splashes from coming into contact with the body. This personal protective equipment (PPE) is essential to minimize the risk of contamination and ensure the safety of the individual handling these hazardous substances.

In this context, the other options do not provide adequate protection against chemical exposure. Sandals and non-specialized footwear may leave the feet exposed to spills, while a sun hat does not serve any protective function against chemical exposure. Hence, the adoption of a chemical-resistant apron is a vital safety measure in pesticide handling.
