An apparatus comprising a vest constructed using woven tubing which generally forms a mesh throughout the vest. The tubing is connected with a reservoir, wherein the tubing and reservoir are filled with electrically conductive fluid. The fluid communicates with a pair of leads to maintain a constant, low-level electrical contact therebetween. The woven tubing is covered with cloth-like material and a hardening substance, such as epoxy. Hence, the tubing will break when the vest receives a significant impact. When the tubing is broken, the fluid escapes from the tubing and breaks the electrical contact between the leads, whereby a transmitter is activated to send a recorded message. In addition, a position sensor is attached to the transmitter for activating the transmitter to send the recorded message if the apparatus is maintained in a non-vertical position for a predetermined period of time.
