Which statement about containment pads is true?

Containment pads are specifically designed to prevent the unintended release of substances, particularly liquids, into the environment during handling or mixing. When large quantities of pesticides are being dealt with, these pads play a crucial role in ensuring that any spills or leaks are contained, minimizing the risk of contamination to soil and water resources. This is particularly important considering the potential environmental and safety hazards posed by pesticide spills.

Using containment pads helps in adhering to safety regulations and best management practices, especially in settings where significant amounts of pesticides are mixed or handled. Larger operations, in particular, are more vulnerable to spills due to the volume of materials being moved, making the use of containment pads vital in those scenarios to safeguard both human health and environmental quality.

The other options lack important considerations related to safe pesticide management practices. For instance, containment pads are relevant regardless of whether the substances stored are classified as hazardous. Additionally, while they offer critical protection when dealing with liquid forms, their role is not limited exclusively to liquid pesticides, and storage in a shed does not eliminate the need for them when large quantities are involved.
