NPR reporters used portable analog recorders to capture the voices of protesters and the sound of helicopters, motorcycle engines and police sirens. ![]() On that day, over 20,000 protesters gathered in Washington, D.C., to demonstrate against the Vietnam War. NPR has been using sound to tell the stories of major events in American politics, culture and foreign affairs ever since the debut of its first program, All Things Considered on May 3, 1971. Members of NPR’s Research, Archives & Data Strategy team (RAD), known in the past as the NPR Library, have spent decades preserving and providing access to this important record of American cultural history. To comply with numerous international and federal regulations.Īs technology advances, chemical and biological threats become more sophisticated and dangerous, and the ability to protect and detect becomes ever more challenging.Īt ATC, the men and women of the FS&CBP Branch are proud to provide testing in support of this mission.Librarian of Congress Carla Hayden recently observed that the “sounds of the past enrich our understanding of the nation’s cultural history and our history in general.” For over 46 years, NPR has produced high-quality journalism and programming in partnership with member stations located throughout the country. Similar to the transport requirements for all hazardous chemicals and biological substances, these transport systems must pass rigorous hazardous material transportation requirements FS&CBP supports this effort by performing tests on contaminated remains transport systems. In addition to protecting personnel in theater, the DOD must be prepared to transport chemically or biologically contaminated human remains in a safe manner that protects all involved. Speech intelligibility testing ensures radios are compatible with all required protective equipment. On a reconnaissance mission for chemical, biological, radiological or nuclear weapons, communication is key-but the required personnel protective equipment includes a full face mask and gloves, making it difficult to handle a radio. The Soldier-specific Dismounted Reconnaissance Sets, Kits, and Outfits system has undergone upgrades, including a change in radios that require speech intelligibility testing. To make an informed decision about system capabilities.įS&CBP also answers the call for testing less common, but no less important, real-world needs. Subjecting the system candidates to high and low temperature extremes, as well as to extreme humidity, produces data necessary for the program manager One system currently under test is the Next Generation Chemical Detector, designed to detect and identify chemical warfare agents in real-world scenarios. Of transport over some of the planet’s roughest terrains, in varied environments.Īt any moment, ATC’s Force Sustainment and Chemical/Biological Protection (FS&CBP) Branch might be testing several chemical and biological defense systems. ATC’s test courses and vibration facility are used to assess the ability of the systems to withstand the shocks and vibrations The systems undergo testing in environmental extremes such as low and high temperatures and blowing rain, sand and dust. Army Test and Evaluation Command (ATEC) test center for chemical and biological defense systems, ATC plays a key role in the development and fielding of these systems. Respond and recover within the realm of chemical and biological, as well as radiological and nuclear, defense.Īlthough ATC is not the primary U.S. Armed Forces to prepare, protect, prevent, The ongoing threat of chemical-biological attacks necessitates a broad mission for the DOD’s Joint Program Executive Office for Chemical and Biological Defense (JPEO CBD). The development of modern chemistry in the mid-19th century helped increase the sophistication of toxic weaponry.Īlthough outlawed by the 1972 Biological Weapons Convention and 1993 Chemical Weapons Convention, recent headlines have brought the shadow of chemical and biological warfare back into public consciousness. ![]() ![]() Some of the earliest references to toxic warfare include burning projectiles, poisoning water, catapulting plague-infected bodies and creating blinding smoke screens. ![]() Since sixth century BC, chemical and biological weapons have existed, developing into greater threats over the ensuing millennia. The CBPS undergoes rain testing to determine the shelter’s resistance to rain infiltration.
