If the pesticide is highly toxic, what additional clothing should be worn?

When dealing with highly toxic pesticides, it is crucial to wear protective clothing that minimizes exposure and potential harm. A liquid-proof apron is designed to prevent any harmful chemicals from making contact with the skin, thus providing a vital barrier when handling or applying hazardous substances. This type of protective clothing is particularly important because even small amounts of a highly toxic pesticide can pose serious health risks.

The other options, while offering some level of protection, do not provide the same level of safety as a liquid-proof apron. A cotton T-shirt, for example, is not protective against liquid chemicals and can absorb the pesticide, increasing exposure risk. Rubber galoshes may protect the feet, but they do not cover the body where exposure can occur. Fabric coveralls may offer some protection but typically are not designed to be liquid-proof. In contrast, a liquid-proof apron specifically addresses the need to shield against chemical splashes or spills, making it essential in situations involving highly toxic pesticides.
