1. A monitored wristband configured for use with a personal safety monitoring system, the monitored wristband comprising:
a first mobile device connected to the monitored wristband and containing communication means;
a first band adjustment hole located along a first length of the monitored wristband between the first mobile device and a first tail end of the monitored wristband;
a second band adjustment hole located along a second length of the monitored wristband between the first mobile device and a second tail end of the monitored wristband;
a two-way security screw including a non-standard drive recess and sized for insertion into the first and second band adjustment holes;
a security key including a non-standard drive configured for insertion into the non-standard drive recess of the two-way security screw; and
a first and a second groove extending an entire width of the first and second lengths of the monitored wristband, respectively, the first grove adjacent the first mobile device and between the first mobile device and the first band adjustment hole, the second groove adjacent the first mobile device and between the first mobile device and the second band adjustment hole;
each groove being uniform and uninterrupted along its length and having a thickness less than that of the first and second lengths of the monitored wristband;
each groove further comprising a designed fail point configured to fail at a predetermined pull force on the monitored wristband, wherein the predetermined pull force on the monitored wrist band is less than a pull force required to break adjacent portions of the monitored wristband.
