Starting in 1952, the Chemical Corps began work on a new mask to replace the M9 series. The corps wanted a mask that was more reliable, suitable for any face size and skin texture, and more comfortable in any climate. Utilizing previous work on canisterless civilian masks and an earlier military prototype, Dr. Frank Shanty, a young engineer assigned to the Army Chemical Center, thought of the concept for a new mask on a late-night train to Cincinnati, Ohio. The final result was the M17 Protective Mask, the first canisterless military mask, which was standardized in 1959. The new mask eliminated the problem of having left- and right-handed masks, weighed less, and had reduced breathing resistance. Other mask work included the first tank mask,
the M14, standardized in 1954 as part of the M8 3- Man Tank Collective Protector. In 1959, the corps standardized an improved head-wound mask, designated the M18, that allowed soldiers with head wounds to wear protective masks in contaminated environments. This is clipped from the 1962 film made by the Army Chemical Corps. The film shows various protective gear developed by the U.S. to protect soldiers and civilians in case of chemical warfare, including protective masks and clothing, as well as gear that helped people remove contaminants from clothing and skin.

This was clipped from the video, Safety and Health Hazards in Grain Elevators, produced by OSHA about 1980, to help train OSHA inspectors investigating grain elevators. The entire video is posted to my YouTube channel. Catastrophic grain explosions in the late 1970s killing more than 60 workers and Federal USDA grain inspectors, focused national attention on hazards associated with the grain handling industry. This increased attention by the government, the grain industry and labor unions representing grain workers, led to safety improvements in the industry. The four factors that must be present in any explosive situation are well known and provide a useful framework for thinking about ways to eliminate explosions in grain elevators. The four factors are: fuel source in this case, grain dust. oxygen. ignition source. confinement (a condition that contributes to turning a fire into an explosion). Any measure proposed to reduce the incidence of grain dust explosions must effect changes in at least one of these four factors. In 1979, a General Accounting Office (GAO) report, Grain Dust Explosions An Unsolved Problem (http://www.gao.gov/products/HRD-79-1 ), investigated the grain dust explosion disasters of December 1977 and January 1978 and potential ways to prevent similar disasters. In this report, the GAO recommended that the U.S. Department of Labor evaluate the adequacy of its regulations to prevent grain elevators explosions. In 1987, OSHA issued its Grain Handling Facilities Standard (29 CFR 1910.272), which set mandatory minimum safety standards which maintains these improvements resulting in a 70% decrease in fatalities from grain explosions. On average, the Grain Handling Facilities Standard has prevented 5 deaths from explosions each year, according to the 2003 Regulatory Review of OSHAS Grain Handling Facilities Standard [29 CFR 1910.272] (https://www.osha.gov/dea/lookback/grainhandlingfinalreport.html ).
