30 magg 1852 anni - Steamboat Act of May 30, 1852

Descrizione:

The period from 1847 to 1852 was marked by an unusual series of disasters primarily caused by boiler explosions; however, many were also caused by fires and collisions. These disasters resulted in the passage of the Steamboat Act of May 30, 1852

The important features of the Steamboat Act were the requirement for hydrostatic testing of boilers and the requirement for a boiler steam safety valve. The act further required that both pilots and engineers be licensed by the local inspectors.
