Which personnel are allowed in restricted areas of the airport?

Access to restricted areas of the airport is strictly regulated to ensure safety and security. Authorized personnel typically include those who have received specific training and have been granted permission to enter these sensitive zones. This includes Airport Rescue Fire Fighters (ARFF), who are trained to respond to emergencies, as well as other authorized personnel such as security officers and certain airport operations staff.

Having only trained and authorized personnel in restricted areas ensures that the proper protocols are followed, maintaining both safety during emergencies and security against potential threats. This limits access to individuals who have a legitimate reason to be in those areas, thus reducing the risk of unauthorized access and potential incidents.

The other choices do not accurately represent the regulations surrounding access to restricted airport areas, as unrestricted access would compromise safety and security measures established at the airport.
