DISCLAIMER

The Planning Guidelines and Design Standards (PGDS) for Checked Baggage Inspection Systems (CBISs) is being distributed under the sponsorship of the Transportation Security Administration (TSA) of the U.S. Department of Homeland Security (DHS) in the interest of information exchange. The U.S. Government assumes no liability for the contents or use of this document.

The purpose of the document is to present TSA’s requirements and documented best practices for implementing a high-performance and cost-effective CBIS. This document captures TSA’s requirements for a CBIS project from the beginning stages of design through commissioning of the system. Best practices are meant to highlight practices that have proven successful during implementation and that TSA recommends for the Project Sponsor’s consideration during the design and construction of a CBIS.

COMPLIANCE LANGUAGE DEFINITIONS

When used in the PGDS, the terms Requirement, Best Practice/Guidance, and Support statements shall be defined as follows:

Requirement – a statement of required, mandatory practice. All requirement statements are presented in underlined text. The verb “shall” is used.

The verbs “should” and “will” are not used in requirement statements.

Best Practice and Guidance – a statement of recommended, but not mandatory, practice. These statements are generated from lessons learned. These statements are geared to inform the reader of known effective practices that have proven successful during implementation. Best practice and guidance statements can be identified within the document by the use of the verb “should”. The verbs “shall” and “will” are not used in best practice or guidance statements.

Support – an informational statement that does not convey any degree of mandate, recommendation, authorization, prohibition, or enforceable condition. The verbs “shall” and “should” are not used in Support statements. The verb “will” can sometimes be used in support statements when referencing things that are the government’s responsibility.

PGDS APPLICABILITY

CURRENT VERSION

Designs for new CBISs shall comply with the requirements set forth in this version of the PGDS. See for other project types and their PGDS compliance.

Chapter 4

All CBIS will be tested to requirements as established in the Commissioning and Evaluation Testing appendix of the latest version of the PGDS in effect at the time of testing. This will allow TSA to obtain the best set of test data to evaluate CBIS performance and to recommend fixes or for Checked Baggage Inspection Systems iii December 30, 2022 improvements to the system. For Operational Analysis Reports and CBIS that are being upgraded or changed, TSA reserves the right to evaluate the CBIS against the most current published PGDS version.

PRIOR VERSIONS

Any project sponsor that has received formal confirmation from TSA of the receipt of the complete 30% Detailed Design Package for a CBIS project prior to the publication date of this version of the PGDS shall continue to be governed by the PGDS version in effect at the time of such confirmation. Projects that have passed the 30% Detailed Design phase—including those systems currently under construction or in operation— with TSA approval shall be held to the design standards specified by that approval (either under the previous PGDS versions or prior standards in place before the publication of Version 1.0 of the PGDS).

DELAYED OPENING OF CBIS

TSA reserves the right to require a project sponsor to resubmit the 30% Detailed Design Package under the requirements of the latest PGDS if the CBIS has not passed the Integrated Site Acceptance Test (ISAT), according to the PGDS version in effect at the time of the original 30% Detailed Design Package submittal, within two years of TSA approval of the original 30% Detailed Design Package.

INDUSTRY COLLABORATION AND COMMENTS

TSA has been collaborating with an Industry Working Group (IWG) that represents airlines, Baggage Handling System (BHS) designers, manufacturers, and consultants to finalize recommended changes to PGDS Version 7.0.

The PGDS is updated regularly to ensure that its guidance and standards reflect the current technology and operating environment. The IWG will continue to meet with TSA to maintain the collaboration and consider potential changes for incorporation into the next version of PGDS.

The public and industry are invited to submit comments to TSA’s rom the date of PGDS publication.

Comments, as well as TSA proposed changes, will be shared with the IWG prior to each meeting and will be reviewed and discussed during the sessions. Any additional comments provided through the IWG will also be considered during these sessions.

PGDS mailbox at pgds@tsa.dhs.gov f

The TSA values all comments and input from industry stakeholders, but only those comments and input determined to enhance and improve the PGDS will be incorporated in the next release of the PGDS. An example of the standard form for comments is provided in Appendix A, Section A.11.

The comment form can be found at the using the search term “PGDS”. SAM.gov website https://www.sam.gov mailto:pgds@tsa.dhs.gov
