What should visitors be informed about upon entry regarding security measures?

Visitors should be informed about security screenings or bag checks required for entry as part of the necessary protocols to ensure the safety and security of everyone present. This information is crucial because it prepares visitors for what to expect as they enter a facility and helps facilitate a smooth and efficient entry process. By communicating the security measures upfront, visitors are made aware of any restrictions regarding what items they can bring inside, thus minimizing surprises and promoting compliance with safety regulations. This proactive approach contributes to an overall secure environment, where everyone understands the necessary procedures in place for their protection.

Other options, while important, do not directly address the immediate concerns related to security upon entry. Visitors may need to know about available resources or emergency exit routes, but these details are not as critical as understanding the specific security measures that will affect their entry process.
