Performance of Soldiers Executing Vehicle Maintenance Tasks Under VariousConditions of Mask Wear

摘要

In an attempt to obtain information on field operational effectiveness duringrespirator wear alone, 7 soldier groups of 4 completed preventive maintenance checks and services (PMCS) on an M998 vehicle under conditions of mask and no mask wear during field exercises. Mask wear conditions were selected to obtain performance time data under best, moderate, and worst cases of encumbered vision and communications that a respirator could reasonably impose upon a wearer. Volunteers also rated perceived exertion levels required to perform PMCS tasks and provided subjective feedback concerning what factors of mask wear were most important to them for completing the assigned tasks.
