Abstract:
1. A system for training firefighters to remain below a heat critical vertical boundary, the system comprising: an emitter configured to establish a height limit, the emitter emitting a single signal; a vertical support member adapted to establish the height limit at the vertical boundary; and a wearable sensor configured to emit an alarm signal responsive to its intrusion above the vertical boundary, the sensor positioned to face towards the emitter when the firefighter is in a crawling or prone position; wherein the emitter is adapted to turn 360° about the vertical support member to establish the vertical boundary around a 360° axis to replicate a heat critical vertical boundary to train firefighters; the emitter and the vertical support configured to steadily move the vertical boundary downward while the emitter is rotating during a training exercise from a first vertical level to a lower second vertical level to replicate movement of the heat critical vertical boundary caused by smoke and heat that accumulates during a fire.
