What is a key element of the In-and-Out Policy for visitor management?

The key element of the In-and-Out Policy for visitor management emphasizes that no visitors are allowed after hours. This aspect of the policy is crucial for maintaining security and ensuring the safety of both employees and visitors. Restricting visitor access after hours helps to minimize risks related to unauthorized access, potential security breaches, and safety concerns when facilities are less staffed or monitored.

The other options, while they may represent reasonable visitor management practices in specific scenarios, do not capture the core security focus of the In-and-Out Policy. For instance, requiring visitors to register online prior to arrival may enhance organizational efficiency but doesn't directly address after-hour safety. Similarly, enforcing an escort policy for visitors ensures supervision but may not be practical if there are no visitors allowed after hours. Lastly, restricting visitors from using facilities can be a management decision but doesn't inherently contribute to the safety and security objectives that the policy aims to uphold.
