To triple-rinse a pesticide container, how should it be filled for each rinse?

To effectively triple-rinse a pesticide container, the correct procedure involves completely filling the container with diluent each time. This thorough filling ensures that the interior surfaces of the container are fully contacted by the rinsing liquid, allowing for the maximum removal of any pesticide residues.

By completely filling the container, any residues that may cling to the sides or bottom are loosened and can be effectively flushed out during the rinsing process. This method is a critical step in responsible pesticide management, as it helps prevent environmental contamination from leftover chemicals. Each rinse should be followed by a thorough emptying of the container, ensuring that the rinsate is disposed of properly according to regulations.

The other options do not provide the same level of efficacy in rinsing. A half-fill or a quarter-fill may not effectively remove all residues, and dipping the container quickly in water does not allow for sufficient interaction between the rinsate and the pesticide residues. Therefore, that complete filling is crucial for ensuring the safety and proper management of pesticide containers.
