Which of the following practices is NOT recommended for transporting pesticides?

Using open containers for liquids is not recommended for transporting pesticides because it poses significant risks to safety and environmental health. Open containers can lead to spills and leaks, resulting in contamination of the transport vehicle, exposure to individuals handling the containers, and potential harm to the surrounding environment. Proper pesticide handling requires that liquids be transported in sealed, appropriate containers specifically designed to prevent leaks and spills.

In contrast, keeping containers upright helps maintain their integrity and minimizes the chance of leaks. Securing containers is vital to prevent movement during transport that could lead to accidents or spills. Clearly labeling containers ensures that anyone handling or coming near the pesticides is aware of the contents and associated hazards, leading to safer handling practices. Therefore, using open containers undermines these essential safety protocols, making it a practice to avoid.
