Thats a great point. I can only imagine that there is specific instructions in the building rules and regulations. It would probably read like this:

Thomas Building North Operational Policy
Chapter 37
Section 112.943
Paragraph 273.1-4

"Any opening of boxes with a sharp instrument will be carried out only by those that are trained, and authorized to use box opening devises. Only "Opening Agents" (OA) shall be permitted to open said items. The devices include but are not limited to: knives, box cutters, razor blades, letter openers, steak knives, table knives, multi tools, any sharp object, etc..

Any person not authorized to use such items on the premises shall have his/her boxes opened by contacting an authorized OA on their floor.

To locate your OA you can find the necessary request forms in the building administrator's office.

The names and license numbers, along with a copy of photo ID, of all current OA's are located in a sealed container in the main security office."
