The National Institute for Occupational Safety and Health (NIOSH), National Personal Protective Technology Laboratory (NPPTL) sought stakeholder input regarding a request from the Department of Defense (DoD). The request is for a proposed modification to the CBRN APR Statement of Standard to allow for mechanical connectors other than the specified single 40-mm thread connector. The DoD is seeking modification of the standard to allow DoD first responders to use a newly developed respirator, the Joint Service General Protective Mask (JSGPM), for respiratory protection on military installations in the United States, or when called upon to support civil authorities. The JSGPM uses a bayonet mounted, dual filter design instead of the single standard 40-mm screw mounted canister. DoD's request is to supplement the existing NIOSH standard with an alternate design for DoD application.

Information submitted to the docket will be considered in the context of development of conceptual standards, as well as updating equipment performance requirements to improve respirator user safety and health.
