• Heat stress
Heat injury is a major issue for firefighters as they wear insulated clothing and can not shed the heat generated from physical exertion. Early detection of heat issues is critical to stop dehydration and heat stress becoming fatal. Early onset of heat stress effects cognitive function which combined with operating in dangerous environment makes heat stress and dehydration a critical issue to monitor. Firefighter physiological status monitoring is showing promise in alerting EMS and commanders to the status of their people on the fire ground. Devices such as PASS device alert 10–20 seconds after a firefighter has stopped moving in a structure. Physiological status monitors measure a firefighter's vital sign status, fatigue and exertion levels and transmit this information over their voice radio. This technology allows a degree of early warning to physiological stress. These devices are similar to technology developed for Future Force Warrior and give a measure of exertion and fatigue. They also tell the people outside a building when they have stopped moving or fallen. This allows a Fire Chief to call in additional engines before the crew get exhausted and also gives an early warning to firemen before they run out of air, as they may not be able to make voice calls over their radio. Current OSHA tables exist for heat injury and the allowable amount of work in a given environment based on temperature, humidity and solar loading.
• Structural collapses
Another leading cause of death during firefighting is structural collapse of a burning building (e.g. a wall, floor, ceiling, roof, or truss system). Structural collapse, which often occurs without warning, may crush or trap firefighters inside the structure. To avoid loss of life, all on-duty firefighters should maintain two-way communication with the incident commander and be equipped with a Personal Alert Safety System device on all fire scenes and maintain radio communication on all incidents(PASS). Francis Brannigan was the founder and greatest contributor to this element of firefighter safety.
