Abstract: A firefighter's safety apparatus includes a first system located in a firefighter's helmet and a second system located at a central station. The first includes a power source, an ambient temperature sensor for relaying ambient temperature information to a microprocessor, a first on/off light source and a second light source coupled to the microprocessor for emitting a status alarm signal when the temperature sensed is above a preset level. An audible alarm is coupled to the microprocessor for emitting an audio signal when the temperature sensed is above the preset level. A manually operated panic switch causes a transceiver coupled to the microprocessor to send a radio signal to the central station if the firefighter is injured or does not move for a preset time and activates the audio alarm. The second system includes a transceiver, a power source and a microprocessor and a power source electronically coupled.
