What is the main purpose of security personnel in terms of safety?

The primary role of security personnel is to ensure the safety and security of people and property. This involves a range of responsibilities, including monitoring for potential threats, preventing criminal activity, responding to emergencies, and maintaining a safe environment for guests and employees. Security personnel act as a deterrent against crime and are trained to respond quickly and effectively to various situations, thereby protecting not only physical assets but also the well-being of individuals present in a given area.

In contrast, the other choices do not align with the core responsibilities of security personnel. For instance, entertaining guests or overseeing premises focuses on hospitality rather than security. Monitoring employee productivity is unrelated to safety and security functions. Collecting payments from clients pertains to financial transactions, which fall outside the scope of security duties. Thus, ensuring safety and security is the fundamental purpose of security personnel, making it the correct answer.
