Full-body chemical-resistant protective clothing must be worn by employees handling minimal exposure pesticides, except when they are:

Full-body chemical-resistant protective clothing is essential for employees handling pesticides, as it minimizes the risk of skin exposure and potential harm from chemicals. However, there are specific scenarios where this level of protection may be relaxed based on the nature of the application method and the expected exposure risks.

When injecting pesticides into the soil with vehicle-mounted or towed equipment, the method typically creates a barrier between the operator and the pesticide, resulting in minimal direct contact. This application method often involves delivering the pesticide in a manner that reduces potential exposure risks, as the operator is not likely to come into direct contact with the chemical.

In contrast, other options involve greater exposure risks, such as applying pesticides with a hand spray, handling undiluted pesticides, or mixing them in a treatment facility, which typically requires full protective gear due to the significant potential for skin contact or inhalation of pesticide particles or aerosols. Thus, option B stands out as a reasonable exception to the requirement for full-body protective clothing under specific conditions, reflecting a more nuanced understanding of the risks involved with different pesticide handling techniques.
