AbstractA monitoring and alarm system allows a firefighter to monitor a variety of safety related parameters during firefighting activities through audible and/or visual means. The system monitors the pressure in the firefighter's breathing system and also monitors ambient temperature and motion of the firefighter. An audible alarm is activated to indicate a potential emergency situation relating to low remaining air time, impending thermal breakthrough or lack of motion of the firefighter.
