During the May 1 holiday, all regions have also ushered in the peak of passenger flow, and also challenged the security inspections of major scenic spots and transportation. When he was 51, he was ready to go out to play and wash his soul. When going to the subway for security, the luggage just passed the X-ray security inspection machine and the security inspector shouted: "There are three bottles of liquid in the bag." I thought that this was to try the rhythm of a drink, but another security examiner asked Xiao Bian to take out the water and put it on a box-shaped device. He checked the three bottles of water and released them in total for no more than 10 seconds. Now. Xiao Bian went to the drinks before the security screening, are to let the test take a sip, but sometimes direct release.
In addition to "please try a drink" there is no other liquid security method
As we all know, there have been many public safety accidents in the modern society. Therefore, the detection of safety in public areas has begun to take hold. Airports, trains, and subways, for example, are the public areas in which traffic is quite large, plus 513 days of vacation. , has become the peak of travel, security and security requirements are even more stringent, in Nanjing, Beijing and other important cities have begun to implement "every package will be seized, every liquid will be seized, every person will be seized."
Then the question is, what should the subway check? What are the main security screening equipment?
X-ray baggage inspection machine
There will be X-ray baggage inspection machines at airports and railway stations. X-rays are used to scan the contents of baggage. It is possible to detect whether there are contraband products without opening the bag. The security inspector distinguishes some of the contraband by staring at the display screen through the color and shape of the items on the display. For example, the colors of liquids are orange, the firecrackers are green, the metal objects are black, and the plastics are blue. If there are liquids or contraband in the bag, the 'postman' will be notified to open the bag for inspection.
The setting of the X-ray baggage inspection machine at the general airport and station has its own special features. That is, a camera is installed on both ends of the conveyor belt. These two cameras are mainly used to monitor security equipment X-ray machines, in order to prevent passengers from taking packets wrong or to deal with some disputes, to facilitate the first time to access video.
Explosive detector
Explosives detectors mainly detect the composition of powdered explosives. If the X-ray baggage inspector suspects that passengers have explosives in their baggage, the security inspector will first use the test strips to take samples, and then put the strips in the machine to detect if K powder, TNT and other contraband products are detected. The machine will alarm. Once explosives appear, they will be immediately put into the explosion-proof ball to prevent explosion damage.
Liquid tester
If the baggage carried by the passenger passes through the X-ray baggage inspection machine and is detected to contain liquid, it needs to be checked out again. The benchtop liquid tester can detect bottled liquids and cans of liquids. Normal water and beverages are placed on the tester and the green light is on. If it is a contraband such as gasoline or alcohol, the red light will be on. In addition to the bench-top liquid tester, the security checkpoint will be equipped with a portable liquid checker to facilitate temporary detection when there are more passengers.
Liquid security instrument is a security inspection instrument specially used for detecting flammable and explosive liquids. It uses quasi-static computed tomography (CT) technology to determine the flammability and explosiveness of the liquid to be measured by determining its permittivity and conductivity. The detector can distinguish liquid explosives, gasoline, acetone, ethanol, and other flammable and explosive liquids from safe liquids such as water, cola, milk, and juice without directly contacting the liquid.
The use of this instrument is very simple. When using, only need to place the detector probe on the side of the container to be tested, detect the height lower than the liquid level in the container, and press the detection button. The green LED indicates that the liquid in the container is safe; the red LED indicates that it is lit at the same time, indicating that the liquid contains flammable and explosive elements. The detector does not contain ions, microwave radiation sources and other potentially dangerous elements and is safe to operators.
Liquid security instruments have not yet been popularized. Due to various factors, the standards for liquid security inspections in various places are not uniform. Therefore, many people may not understand the process of liquid security inspection. When passing security, they will also feel disgusted when they try to take a drink.
Liquid security in several situations:
1. If the liquid held by the passenger is a beverage, the passenger will be invited to try it or use a liquid detector to check it; if it is a non-beverage product, it should be checked directly with the instrument.
2. If the passenger puts the liquid in the bag, the security inspector will ask the passenger to take out the liquid after going through the security checker. If it is a drink, he will invite the passenger to try it out, or use the liquid detector to check; if it is non-beverage, then directly Use the instrument for inspection.
3, there is a special case, if passengers have just purchased a lot of bottled liquids from shopping malls or supermarkets, if it is more than one bottle of the same liquid, security checkpoints will take the form of sampling, randomly selected one or two bottles of equipment for inspection.
4, passenger flow will also be due to holidays, early morning peaks and other factors, so depending on the passenger flow situation, in order to improve the speed of the pit stop to make changes, the peak period of time with the bag into the security testing equipment, security checkers will not force passengers must "take a drink "Stuck again.
