Final answer:
The National Safety Council adopted a resolution condemning alcohol during the era of Prohibition in the early 20th century, although the exact year is not specified. This was part of a larger societal move against alcohol, led by groups like the WCTU and the Anti-Saloon League, to address alcohol-related social issues, including industrial accidents.
Step-by-step explanation:
The question pertains to the historical era when the National Safety Council adopted a resolution condemning alcohol as a cause of industrial accidents, which closely aligns with the period of Prohibition and the temperance movement in the United States. The National Safety Council's resolution was indicative of the broader sentiment during the early 20th century that alcohol consumption negatively impacted society in various ways, including workplace safety and efficiency. This period saw significant advocacy from groups such as the Women's Christian Temperance Union (WCTU) and the Anti-Saloon League, who linked the consumption of alcohol with moral decay and societal problems, ultimately leading to the ratification of the Eighteenth Amendment in 1919.
While the exact year that the National Safety Council adopted this resolution is not provided, it is within the context of Prohibition, which began in 1920 with the implementation of the 18th Amendment. The amendment prohibited the manufacture, sale, and transportation of alcoholic beverages and was fueled by concerns including worker absenteeism, industrial accidents, and domestic violence. Despite these efforts, Prohibition was eventually repealed on December 5, 1933.
