This report documents a systematic approach toward implementing an improved ensemble for the mine rescue team system that will protect against the hazards of mine rescue and recovery and will also afford improved performance through increased comfort and maneuverability, lighter burdens, and improved human engineering designs. Volume 1 is a detailed discussion of the approach to, and results of, three tasks. In the first task, the mine rescue team's protective needs were defined along with the test methods required to evaluate whether a particular piece of gear met these needs. The second task assessed existing gear against performance criteria and standards developed in the first task. The third task consisted of the conceptual design and construction phases of the mine rescue team's protective ensemble. Special consideration was given to advanced concepts, materials, and equipment.
