Since today, Ningbo Lishe Airport has been upgraded to security. A trace explosives detection system will be added at the entrance of the terminal building to carry out explosion tests on passengers who carry luggage into the terminal building. New inspections will increase waiting time, and passengers should wait 5 minutes ahead of schedule.

Explosion-proof inspection channel is set at the entrance to the terminal building. The airport security personnel will hold a handle. The top of the handle has a piece of white paper with a width of 1cm and a length of 4cm, which resembles a band-aid.

The security personnel will check the “band-aid” on the lap of the passenger’s luggage or the edge of the box, and then take a test on the special instrument next to it to check whether there is any explosive in the bag. It will take no longer than 2 minutes to open the luggage or luggage. The instrument is called "trace explosive detector". It is sensitive to detection. It can detect and discharge explosives or explosive devices inside the bag through traces of explosives, people with explosives or just those who have contacted explosives. Or items can be detected by the instrument.
