What is a primary reason security officers must remain alert at all times?

Security officers must remain alert at all times primarily to detect potential threats or emergencies. This vigilance is crucial in maintaining a safe environment, allowing security personnel to identify suspicious behavior, respond promptly to incidents, and ensure the well-being of individuals in their care. Their role requires constant observation and assessment of the surroundings, enabling them to act quickly and effectively when they notice anything out of the ordinary or potentially dangerous. Maintaining this level of awareness is central to their responsibilities, as the safety of both personnel and the property often depends on their ability to react to threats in a timely manner.
