Assessment to Determine the Thermal Protective Capability of the U.S Marine CorpsModular Sleeping Bag

摘要

An assessment to determine the thermal protective capability of the U.S. MarineCorps modular sleeping bag (MSB) was conducted by the Human Research and Engineenng Directorate of the U.S. Army Research Laboratory, Aberdeen Proving Ground, Maryland, from 6 June through 1July 1994. The purpose of this assessment was to determine the lowest ambient air temperatures at which the patrol, intermediate, and extreme cold weather sleeping bag configurations would provide adequate thermal protection to afford its users with 4 hours of comfortable rest or sleep, and to identify any human factors or design shortcomings. Twelve marines participated in this assessment. The results of this assessment determined that the MSB afforded the subjects with 4 hours of comfortable rest or sleep at an ambient air temperature of + 30 deg F in the patrol bag, at an ambient air temperature of 0 deg F in the intermediate sleeping bag, and at an ambient air temperature of -30 deg F in the extreme cold weather sleeping bag. None of the subjects stated that he or she could not at least rest comfortably for the 4-hour exposure period in these conditions. No human factors or design shortcomings were observed; however, one bag had an additional seam stitched in its lower section, and this was considered to be a possible quality control problem.
