In most major centres you will have to go through a security screening process before you enter the building.
It may be similar to those in airports. Each time you enter the building, you will have to empty your pockets of change, keys and metal objects for examination. Purses, bags or backpacks may be passed through an X-ray to check the contents. If the alarm is set off when you go through the scanning frame, a sheriff’s officer may pass a hand scanner wand over your body to determine the source of the metal.
If you have any objects which are not allowed (pocket knives, scissors, pointed objects), these objects will be taken and kept at the desk. They will be returned to you when you are leaving the building.
