Descripción de Respirator Cleaning and Inspection 1940s:
Using respiratory protection is more than just providing a mask! In the US employers must ensure their proper functioning and have a regular maintenance and cleaning schedule. In general, respirators should be inspected for basic function prior to each use and cleaned as often as necessary to prevent the occurrence of unsanitary conditions. The National Institute for Occupational Safety and Health (NIOSH) provides guidance for selecting cleaning equipment, supplies, and procedures for respirator maintenance at http://www.cdc.gov/niosh/respcln.html . 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).
