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.
A floor drain is a plumbing fixture that is installed in the floor of a structure, mainly designed to remove any standing water near it. They are usually round, but can also be square or rectangular. They usually range from 2 to 12 inches (5.1 to 30.5 cm); most are 4 inches (10 cm) in diameter. They have gratings that are made of metal or plastic. The floor around the drain is also sloped to allow the water to flow to the drain. Many residential basements have one or more floor drains, usually near a water heater or washer/dryer. Floor drains can also be found in commercial basements, restrooms, kitchens, refrigerator areas, locker/shower rooms, laundry facilities, and near swimming pools, among other places.
