What does 5E-14 mandate about pesticide storage during fieldwork?

The correct choice emphasizes the importance of proper labeling for pesticides, which is crucial for ensuring safety and compliance with regulations. Federal and state label registration indicates that the pesticide has been evaluated for safety and efficacy, providing essential information for handlers and users. This requirement helps prevent misuse and protects the environment and public health by ensuring that only approved substances are used and stored according to established safety protocols.

When pesticides are properly labeled, it allows individuals to understand the specific application guidelines, safety precautions, and potential hazards associated with the product. This compliance is particularly important during fieldwork, as it ensures that the substances are handled correctly and that any potential risks to human health and the environment are minimized.

In contrast, the alternatives do not emphasize safety or regulatory compliance adequately. Pesticides being kept exposed, labeled as non-hazardous, or remaining in open vehicles could lead to mishandling, spills, or unintended exposures, thereby undermining the objectives of safe pesticide use and storage as mandated by regulations.
