“We wanted a system that would minimize some of the negative physiological impacts during heavy exertion and extended missions-lower the respiration rate and make it easier to breathe through the filters in a regular protective mask.” The physical stress of rapidly moving through ships, clearing spaces, and potentially dealing with armed suspects can significantly raise respiration and heart rate,” said Daniel Moose, Technical Director for MSRT East. Army Combat Capabilities Development Command’s Chemical Biological Center (CBC) to assess existing Powered-air Purifying Respirators (PAPRs) and recommend models that would be a better fit with MSRT’s current masks, literally and figuratively.

To resolve this issue, S&T enlisted the U.S. The Coast Guard asked S&T to assist in meeting a need to reduce the discomfort of wearing APRs by MSRT teams because discomfort adds to physical stress, which may impede endurance. Some of these operations involve chemical, biological, radiological and nuclear (CBRN) threats and require protective equipment, including air-purifying respirator (APR) masks. The Coast Guard’s Maritime Security Response Team (MSRT) is a tactical unit that specializes in maritime counterterrorism and high-risk law enforcement operations, boarding and securing vessels held by terrorists or criminal groups at home and abroad. The Department of Homeland Security (DHS) Science and Technology Directorate (S&T) is committed to ensuring that all American responders have the tools they need to do their jobs safely and securely-including reliable personal protective equipment that won’t let them down when it matters the most. They are rescuers, law enforcement, border patrol and, in some cases, the Coast Guard is also involved in special operations. Just like their counterparts on dry land, these first responders are called to action when citizens are in distress, when a crime has been committed, and when natural disasters strike. Coast Guard is America's maritime first responder.
