In August 2020, two workers entered a natural gas tanker on a railcar in Hugo and fell victim to vapors. Their deaths, among those of 36 workers in the transportation and tank cleaning industry reported across the extended region since 2016, have been investigated by the U.S. Department of Labor’s Occupational Safety and Health Administration. To reduce the risks faced by tank cleaning workers, OSHA has established a Local Emphasis Program, or LEP, to raise awareness among employers in Region 6 (Texas, Arkansas, Louisiana, New Mexico and Oklahoma) and Region 5 based in Chicago.
