What are common types of respirators used in pesticide handling?

The correct answer highlights the various types of respirators specifically designed for pesticide handling, which prioritize safety and effectiveness in protecting users from harmful exposures.

Air-purifying respirators are equipped with filters or cartridges that remove contaminants from the air, making them suitable for environments where pesticides are being applied. Powered air-purifying respirators enhance this protection by using a fan to draw air through the filters, providing a higher level of comfort and ease of breathing for extended periods. Supplied-air respirators deliver clean air from a remote source, essential in situations where airborne contaminants are particularly concentrated or hazardous.

In contrast, disposable masks, simple filters, and regular dust masks do not offer the same level of filtration and protection as the types specified. Disposable masks and regular dust masks are generally intended for less toxic, non-hazardous environments, while simple filters lack the necessary design to effectively remove pesticide agents from the air. Thus, the use of specialized respirators as outlined in the correct choice is crucial in ensuring safety during pesticide handling.
