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

To effectively triple-rinse a pesticide container, it is important to completely fill it with diluent. This method ensures that the container is thoroughly cleaned, allowing the diluent to come into contact with all inner surfaces. By filling the container completely, you maximize the rinsing action, helping to dislodge any pesticide residues that may adhere to the sides or bottom of the container.

Triple rinsing involves filling the container with water or another appropriate diluent, securely capping it, and then shaking it vigorously to mix the rinsing solution with any remaining pesticide. After that, the liquid should be emptied out, and the process is repeated two more times. This thorough cleaning process is crucial for minimizing environmental contamination and ensuring that any residues are removed effectively before disposal or recycling of the container.

Other choices, such as filling it halfway, dipping it quickly in water, or only filling it a quarter way, do not provide the same level of contact and rinse effectiveness and are therefore not adequate for ensuring the safe removal of pesticide residues.
