X-Ray Baggage Scanners |
(Chapter 3 Metal Detection, Continued)
Instructions for the scannee
Hopefully, as students grow accustomed to what items in their bags and purses trigger an alert to the operator of the x-ray equipment, they will tend not to bring these items to school with them. This may not be the case for disruptive students, who may go out of their way to slow down the system. School administrators may want to consider having some type of consequences in place if this behavior continues.
Educating students and parents in advance about what to expect from the x-ray process and which of the items they carry will result in bag searches can help speed up the process at the beginning of a scanning program. However, do not share with the students information regarding the system's weaknesses and what makes it difficult to recognize weapons hidden inside bags. This information should remain restricted to appropriate school and law enforcement personnel responsible for security.
A simple set of instructions located at the x-ray detector can remind students quickly of what is expected of them. An example of such a sign is:
Place all large jewelry, watches, belts with metal buckles, large keyrings, loose change, and other detector-sensitive items in your backpack or purse. (This first sentence is for a school that also has portal metal detectors.)
Lay all books, notebooks, purses, bags, lunches, backpacks, briefcases, hats, coats, jackets, and electronic devices on their widest side on the conveyor belt. (Adjust according to whatever orientation is best for your equipment.)
Do not stack items; place them on the conveyor belt separately. It is easy to reduce the chance of security personnel going through your things manually-DO NOT CARRY A LOT OF JUNK IN THEM!
There should be a sign on the other side of the x-ray detector:
Please immediately check for all of your personal valuables and possessions. The school is not responsible for your things. If you have irreplaceable items, please do not bring them to school.
