Heathrow Airport is trialling new 3D X-ray scanners that could allow passengers to keep liquids in their hand luggage during security checks. The machines, which use computerised tomography (CT) technology, enable security staff to inspect items without requiring them to be removed from bags, and can detect explosives.
The current rules, introduced in 2006 after a terror plot was foiled by UK police, limit liquids to containers of no more than 100ml, which must be placed in a small transparent, resealable plastic bag and removed from hand luggage. The Department for Transport (DfT) said a small number of trials would last between six and 12 months.
A DfT spokesperson said: 'The UK has some of the strictest security measures in the world, and we are leading the way in using new technology to improve security screening and provide a better experience for passengers. If successful, this could lead in future to passengers no longer needing to remove items from hand luggage for screening.'
The new scanners have also been tested at Amsterdam's Schiphol airport and John F Kennedy airport in New York. The DfT added that the technology allows baggage screeners 'to use 3D imagery to look at objects from all angles'. A Heathrow spokeswoman confirmed the airport was 'looking at new technologies that can both improve the passenger experience and strengthen our security'.
During the trial period, the existing rules remain in place, and passengers should expect to remove items if requested.
