An exposure-indicating supplied air respirator system comprises a head top, a clean air supply source and a portable personal communication hub. The head top comprises a visor that is sized to fit over at least a user's nose and mouth, a position sensor secured to the head top, and a head top communication module. The clean air supply source is connected to the head top that supplies clean air to the interior of the head top. The position sensor detects whether the visor is in a closed position or in an open position and the head top communication module communicates the visor position to the personal communication hub. If the personal communication hub receives a signal indicating the presence of a hazard, and if the visor is in an open position, an alert is generated.
