When do trucks containing pesticides need to be locked?

• A. Only at night
• B. Only when working
• C. Always when not in use
• D. Only on weekends

Answer: (C)

Trucks containing pesticides need to be locked always when not in use to ensure the safety of the chemicals and prevent unauthorized access. This practice is essential for guarding against accidental exposure, spillages, or theft of hazardous materials, which could pose significant health risks to the public and the environment.

Maintaining security by keeping these vehicles locked at all times helps to adhere to regulations designed to protect both workers and the community where pesticide application occurs. In addition, it demonstrates responsibility in the management of potentially dangerous substances.

The other options suggest limited or conditional security measures, which do not adequately address the need for consistent safety protocols in handling pesticides. Always locking the trucks provides a reliable safeguard against misuse and ensures compliance with safety guidelines.
