What is required for stored pesticides to ensure safety?

The correct choice highlights the importance of secure storage with access restrictions for stored pesticides to ensure safety. Pesticides can pose a significant risk to human health and the environment if not handled properly. Thus, keeping them in a secure storage area helps prevent accidental exposure or misuse.

Restricting access ensures that only trained and authorized personnel can handle or use these chemicals, which minimizes the risk of accidental spills, leaks, or unauthorized use by untrained individuals, including children and pets. This practice not only adheres to safety regulations but also reflects best practices in pesticide management.

While proper labeling is essential for safety and communication regarding the hazards of the chemicals, it does not provide the physical security needed to prevent access. Open storage for public safety contradicts safety protocols, as it increases the risk of exposure. Unlimited accessibility ignores the potential dangers posed by pesticides, allowing anyone, including those without proper training, to have access to the materials, further increasing the risk of accidents or misuse.
