Death By Molasses

A roaring wave of syrup swept through the North End of Boston on 15th January, 1919, in an event that claimed 21 lives, including 2 children, and came to be known as the “Great Molasses Flood”. 

At the heart of the disaster was a rushed, badly built industrial tank: the steel was too thin, the materials were faulty, leaks were ignored (and literally painted over), and warning signs were dismissed. The explosion hurled molasses at around 35 miles an hour, piling up in waves as high as eight meters. People were knocked off their feet, buildings were crushed, and one man famously woke up on the top floor of his house submerged in syrup.

In this episode, Arion, Rebecca and Olly explain how the tragedy led to a raft of health and safety laws, and America’s first class action lawsuit; reveal how emergency workers finally found a way to clean up after the destruction; and consider how Bostonians felt the aftermath of the explosion for decades to come…
