Door Seal

n. A small, single-use, serial-numbered plastic tag with one-way, one-time loop fastener used to “secure” two eye-bolts or hasps, such as on a door and a door frame, and thus provide evidence as to whether or not the door, hatch, gate or other such access point has or has not been opened.

NOTE: Door seals answer the question, “Did this (door, hatch, whatever) open during the time it was supposed to stay closed?” Door Seals are very easily broken, and virtually impossible to repair. The point is not to provide a barrier, but to provide proof that the door or whatever has remained closed, and thereby support the function of the LOCK and ALARM. ALARMS can be disarmed, and LOCKS can be opened, but like Humpty Dumpty, Door Seals can't be put back together again. Likewise, when it's time to be legitimately broken, its serial number has to match the one previously written down in the M.O.D.'s log book, or else you know there's been foul play.
