Restricted use pesticides must be stored where when unattended?

Restricted use pesticides must be stored in a secure, locked enclosure when unattended to ensure safety and prevent unauthorized access. This is important because these pesticides are classified as restricted use due to their potential toxicity and risks to human health and the environment. A locked enclosure minimizes the risk of accidental exposure to these substances, especially by children, pets, or untrained individuals.

While storing them in the application vehicle might seem convenient, it does not provide the necessary security and protection that is required for handling such hazardous materials. Storing pesticides in an open area or merely in a locked enclosure without specifying "secure" also does not meet safety standards for preventing access to these dangerous products. Proper storage is critical to maintaining compliance with regulatory requirements and ensuring the safe handling of pesticides.
