In this study, we evaluated the impact of the concept of an integrated helmet respirator on respiratory protectioneffectiveness as compared with a helmet and respirator worn in a traditional nonintegrated manner. The integratedsystem allows a wearer to use the respirator without requiring removal of the ballistic protective helmet. We found thatthere were no significant differences for overall protection factor PF results or specific exercise PF results between theintegrated and nonintegrated systems, regardless of night vision goggle NVG usage. In addition, NVG usage did notresult in significant differences within the integrated or nonintegrated configurations. Further investigation is needed todemonstrate that integrated helmet respirator systems that use ballistic materials with greater mass can achieve similarlevels of respiratory protection.
