A History of Respirators from 500 BC to 1900 AD

Описание: This clips traces the need for a respirator throughout history with re-enacted sequences, including the British study of the death rate among coal miners beginning in 1902. A good brief history of respirators by the U.S. Army Soldier and Biological Chemical Command covers some of the highlights of the long history of the protective mask. It contains wonderful drawings and photographs of both civilian and military respirators. The development of the U.S. Army protective mask dates back to World War I when chemical warfare was first introduced on a large scale. The short publication - HISTORY OF THE ARMYS PROTECTIVE MASK - is available for viewing and downloading at the library of the US Army Chemical Corps Museum: http://www.wood.army.mil/ccmuseum/ccm... . This is clipped from the 1940s film, The Air We Breathe, a ppromotional documentary from the Mine Safety Appliances Company (MSA) on the importance of the air respirator to industrial health and safety. At the end, the film explains that industry and government cooperation has removed the "menace in the air" and urges workers in various industries to use the respirator. This film is available from the National Archives (NARA).
