Ernest DeMaio, was a union organizer and union leader with the Radio and Machine Workers of America (UE). After several years organizing workers in electrical manufacturing in New England, he helped found the UE in 1936. In 1942, he became general vice president of the union, a post he held until he retired in 1974. The men and women who organized the UE were inspired by the need to build an industrial organization (meaning all workers could be part of the union), controlled by the members, with complete equality for all who worked in that industry.
This 1973 speech is from the first conference organized by the Occupational Health Project of the Medical Committee for Human Rights (MCHR) for workers and unions. This conference was held in Chicago at the University of Illinois School of Medicine, co-sponsored by the Medicine School and many union locals. The first COSH Group, the Chicago Area Committee for Occupational Safety and Health (CACOSH) grew out of this conference. COSH groups are private, non-profit coalitions of labor unions, health and technical professionals, and others interested in promoting and advocating for worker health and safety. Today’s National Council for Occupational Safety and Health (National COSH) is a federation of local and statewide "COSH" groups – Committees / Coalitions on Occupational Safety and Health. For more about COSH Groups, link to coshnetwork.org/. The Medical Committee for Human Rights (MCHR) was an organization of doctors, nurses, and other health care providers devoted to promoting civil rights, reaching out to minority groups, and improving the delivery of health services in the United States from 1964 to 1980. MCHR established its Occupational Health Project after OSHA began in 1971with the goal of forming permanent local organizations dedicated to grassroots health education and organization – now known as COSH Groups.

![Grain Elevator Dust Explosions c1980 OSHA
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 ).
