Thermal stress due to heat or cold may impact comfort, the ability to conduct operations, and, potentially, the survival of Warfighters. This report provides background information and methods for characterizing the properties of enclosed spaces (vehicles, shelters, other enclosures) that impact the thermal state of Warfighters. Quantification of the thermal environment of an enclosure consists of measuring air and surface temperatures, humidity, air flow; and radiant load. Methods focus on ...
Hidalgo Equivital(TM) Physiological Monitor and other sensors performance monitoring of physiological status was evaluated, and human data were collected on 12 wildland firefighters (WLFF). The devices were provided to the University of Montana Center for Work Physiology and Exercise Metabolism (WPEM) to collect data relative to energy costs and thermal strain. The Hidalgo system collected, recorded and displayed heart rate (HR), respiratory rate (RR), body position, core temperature (CT), and ...
