NCFO

The International Brotherhood of Stationary Firemen (IBSF) was an American trade union established in 1898 and affiliated with the American Federation of Labor. The union was established as a mechanism for advancing the collective interests of workers engaged in the operation of steam boilers. Originally limited to stationary firemen, in 1919 the AF of L expanded the organization's jurisdictional mandate to oilers and boiler room helpers, and the name was changed to International Brotherhood of Stationary Firemen and Oilers (IBSFO).
