When firefighters enter a burning building, they must keep in physical contact with each other to stay together, which limits their mobility and, when contact is broken, results in injuries and fatalities. The TekAlert E-Team developed the Team Accountability Buddy System (TABS), which uses proximity-sensing wireless technology to allow firefighters to free their hands and conduct more efficient searches while maintaining team integrity. TABS allows firefighters to work a safe distance apart, determined by visibility. When a member of the group is outside the distance limit for thirty seconds, the audible and visual beacon system activates, guiding the group back to the missing firefighter. Each unit is interoperable and compatible with all other units.
