Abstract: Soldiers, first responders, and search-and-rescue personnel are among those whose job requirements include exposure to hazardous and toxic elements. The Joint Service General Purpose Mask (JSGPM), XM50/XM51 is being developed as the next generation of respirators for all ground personnel of the U.S. Armed Forces. The JSGPM, together with personal protective equipment, allows the operators the flexibility to tailor their protection, based on mission threat, thereby minimizing weight, bulk, and heat stress. This study looked at JSGPM from a systems development perspective and evaluated comfort, stability, donning and doffing procedures in comparison to the M40 series mask. Four configurations (M40 series mask with Joint Service Lightweight Integrated Suit Technology [JSLIST, jacket only], XM50 with hood, XM50 with JSLIST [jacket only], and the XM50 with JSLIST [jacket only] and modified mask beard) were tested. The analysis showed that there were no significant differences among any of the characteristics rated for the responses to the comfort and vision correction inserts questionnaire. The results of the comparative questionnaires showed that 94% of the Soldiers rated the XM50 mask as better than the M40 series mask.
