Preparing Dublin Airport for new LAGs legislation

The challenge

EU aviation security legislation has changed. Since the end of January 2014, airports have been required to screen liquids, aerosols and gels (LAGs) with liquid explosive detection systems (LEDS) in passenger and staff search areas. The changes are being introduced on a phased basis. The first phase of implementation, in January 2014, requires screening of LAGs carried in Secure Tamper Evident Bags (STEBs), medicines, and items containing special dietary requirements, including baby food. Subsequent phases are expected to require the screening of clear liquids in clear containers, and finally all LAGs.

There was a need for European airports to prepare for these changes, ensuring they have the appropriate equipment and processes in place to handle demand effectively.

Our role

Dublin Airport wished for a broader understanding regarding the carriage of duty free LAGs in Secure Tamper Evident Bags (STEBs), medicines, dietary LAGs and baby food. DAA asked o&i consulting to help them gather this information to inform their response to the legislative changes.

Our team set up, managed, and analysed a week-long survey, completed by the airport company, across both of the airport’s terminals. The survey covered over 20,000 passengers and provided DAA with current and relevant figures regarding the proportion of LAGs items for Phase 1, and the number of passengers who fail to divest LAGs above and below the 100ml threshold.

Following the survey, Dublin Airport and o&i consulting identified a range of LEDS equipment to evaluate in a series of operational trials. o&i planned and managed a trial of these various equipment types to determine their individual and combined performance in order to inform a subsequent procurement decision.
