Energy Expenditure and Metabolic Heat Production Storage Estimates of Tactical Law Enforcement Personnel during Chemical, Biological, Radiological, and Nuclear (CBRN) Training

摘要

The tactical law enforcement community is involved in a range of missions utilizing various types of personal protective equipment (PPE). They are also exposed to a wide range of environmental conditions. The use of chemical, biological, radiological, and nuclear (CBRN) protective ensembles, either with or without body armor, can add significant thermal stress due to the increased weight and insulating properties of these garments and head gear. High ambient heat conditions, especially with high solar loads, can lead to a rapid increase in body core temperature (TCore). When encapsulated in PPE, the rate of evaporative heat loss is substantially diminished which can lead to more rapid increases in TCore.
