Which would not be considered a good security practice?

Replacing employees often with new personnel is not considered a good security practice primarily because it can lead to a lack of stability and continuity in the workplace. When employees are frequently replaced, it hinders the development of expertise and proper handling of equipment, especially in environments where safety and compliance with regulations are critical.

Continuity allows for the reinforcement of training regarding proper procedures, including mixing and applying pesticides, which is essential for both safety and environmental protection. Employees who are familiar with the operational protocols foster a culture of responsibility and adherence to security measures. Moreover, constant turnover can prevent the establishment of trust and communication among team members, which are key components in maintaining a secure and efficient workplace.

In contrast, the other options—restricting access to sensitive areas, training staff on inventory control, and reporting suspicious activities—are practices that contribute positively to security measures and overall safety in operations that involve pesticides.
