What are Restricted Security Zones in an airport?

What does ZRS mean at an airport?

The acronym ZRS means Security Restricted Areas. In an airport, these are areas where access is limited and controlled for security reasons. These are not public areas or spaces that anyone can enter.

In Spain, airports distinguish between different areas, such as the land side, the air side or operations zone, controlled access zones, restricted security zones and critical zones within those restricted zones. The National Civil Aviation Security Program establishes this organization to apply appropriate security measures in each part of the airport.

What zones can be part of a ZRS

Simply put, a ZRS can include areas of the airport where security controls have already been applied or where sensitive activities for air operations are carried out.

According to the National Security Program, Security Restricted Areas include, at least, areas accessed by already inspected passengers waiting to board, areas through which already inspected checked baggage circulates or is stored, and areas used for the parking of aircraft subject to loading or boarding operations.

This does not mean that all ZRS are the same nor that all accredited people can access any point. Access depends on the authorization granted, the work reason and the conditions established by the airport.

Why do Security Restricted Areas exist?

The ZRS exist to protect civil aviation against unauthorized access, introduction of prohibited items or situations that may affect the safety of passengers, crews, workers, aircraft and facilities.

The general objective of the National Civil Aviation Security Program is to establish the organization, methods and procedures necessary to protect passengers, crews, ground personnel, aircraft, airports and facilities against acts of unlawful interference.

Therefore, access to these areas is not based only on working at the airport. There must be a justified need, a valid authorization and, where applicable, appropriate airport ID accreditation.

What relationship does accreditation have with the ZRS?

Airport accreditation is the document that allows a person to be identified and authorized to access certain areas of the airport. In the case of ZRS, accreditation is especially important because access must be controlled at all times.

The National Security Program indicates that access to Restricted Security Zones will only be authorized for people or vehicles with a legitimate reason for being there. It also establishes that people and vehicles must have accreditation or approved authorization to access.

In practice, accreditation is not a free pass to move throughout the airport. Authorizes access only to permitted areas and for the corresponding activity. In addition, it must be used correctly, pass through the established points and comply with airport regulations. Aena reminds that personal accreditation must be worn visibly, it is personal and non-transferable and may be required by security personnel or the Security Forces and Corps.

Why AVSEC training may be necessary

AVSEC refers to civil aviation security. AVSEC training helps people who work in the airport environment know basic security rules, access controls, the correct use of accreditation and how to respond to certain incidents.

In Spain, non-passengers who need free access to Security Restricted Areas must receive security training so that the corresponding authorization can be granted. This training should provide an understanding of aspects such as legal requirements, the organization of aviation security, access controls, accreditations and notification procedures.

Simply put: if a person is going to access a ZRS unaccompanied, the airport must ensure that they understand their basic security responsibilities.

Accessing without accompaniment does not mean accessing without control

An important idea is that accessing without accompaniment does not mean entering without control. It means that the person can access authorized areas by themselves, always within the limits of their accreditation and airport regulations.

Therefore, before granting a restricted zone accreditation, documents, verifications and training may be required. In the application forms for personal accreditation to a restricted area, Aena includes among the requirements that the company has trained the beneficiary in civil aviation security in the part of the National Security Program and the Air Safety Law that affects them.

Summary: what you should remember about ZRS

ZRS are areas of the airport with limited access for security reasons. They are created to protect air operations, control who enters, prevent unauthorized access and reduce risks for passengers, workers, aircraft and facilities.

Accessing a Security Restricted Area in Spain normally requires a justified reason, a valid accreditation or authorization and, in many cases, appropriate AVSEC training. The accreditation allows you to work in authorized areas, but always under the rules of the airport and the National Security Program.

• Airport Security Restricted Areas are not public spaces.
• Access is dependent on justified work need and valid authorization.
• AVSEC Spain training may be necessary for unaccompanied access.
• Airport accreditation only allows entry into authorized areas.
