"Firefighting is exceptionally strenuous and dangerous work that can have significant health consequences for first responders, including death. According to the National Institute of Occupational Safety and Health, of the 1,094 fire-fighters who lost their lives from 2005-2015; the leading causes of death (57 percent) were cardiac arrest or asphyxiation. Remote monitoring of vital signs that measures heart rate, respiration and other physiological factors can help re-duce negative physical outcomes. [...] To protect the health and lives of firefighters, the Department of Homeland Security Science and Technology Directorate (S&T) is developing a Wireless Physiological and Environmental Monitoring (WiPEM) system that transmits relevant individual data back to an incident commander and enhance the safety of first responders. The system transmits critical physiological status data on multiple first responders to the incident command station for monitoring purposes. It also provides incident commanders with critical environ-mental conditions surrounding a first responder to enhance situational awareness."
