The Pemberton Mill in Lawrence, Massachusetts collapses…
January 1860 CE
The tragedy will become a rallying point for efforts to improve safety standards in industrial workplaces.
The collapse of the Pemberton Mill will be determined to have been caused by a number of preventable factors.
Ignoring already questionable load limits, extra heavy machinery had been crowded into the upper floors of the factory.
Investigators will also discover substandard construction.
The brick walls were improperly mortared and supported.
The iron pillars supporting the floors were cheap and brittle but had been installed nonetheless.
