At all metro stations in China, there are such devices:
If a suspicious object is found in the subway, the station is not closed for half a day – there will be a traffic collapse.
Suspicious object is immediately placed in this device.
The cover is practically hermetic, it protects both from explosion and from exposure to poisonous substances. Even if an explosion happens – the device will take a blow at itself, the station and people will not suffer.
Later the sappers will understand what’s inside.
They are installed at the entrance to the metro – where the bags are scanned and people pass through the metal detectors (almost like at the airport) – to immediately place a suspicious object inside as well as in different places inside the station – so as not to run far from the bomb .
