For trucks we should ensure to start to inspect from small parts further detect the confirmed cargos with other instrument before unloading the cargos Remember to search each cargo piece after they are unloaded then inspect the truck again Besides searching the cargos check whether there is new marks or false interlayer For successful search understanding of the vehicle is also very important For buses confirm the locations of suspicious traces have the passengers of such location get off Search the suspicious passenger and his seat surrounding The suspicious location may be with the luggage or in the false interlayer of the bus Find the suspicious points with the detector search the bus once again quickly with police dog Remember police dog will not search those who have taken drugs 3 3 5 Inspection of container ports For container port inspection the safety of the operator should be considered first for that container ports are mostly very busy Inspection of stacked containers will be very dangerous The operator should be accompanied by the professional personnel from the container port and adopt sufficient safety protection measures Or just inspect when the container is in and out of the port Step 1 Step 2 The basic steps to inspect container ports are as follows Subdivide the port into many small areas Inspect all the containers however if the containers are stacked
