Boston Molasses Disaster

The Boston Molasses Disaster, also known as the Great Molasses Flood and the Great Boston Molasses Tragedy, occurred on January 15, 1919, in the North End neighborhood of Boston, Massachusetts in the United States. A large molasses storage tank burst, and a wave of molasses rushed through the streets at an estimated 35

Several factors that occurred on that day and the previous days might have contributed to the disaster. The tank was constructed poorly and tested insufficiently. Due to fermentation occurring within the tank, carbon dioxide production might have raised the internal pressure. The rise in local temperatures that occurred over the previous day also would have assisted in building this pressure. Records show that the air temperature rose from 2°F to 41°F (from −17°C to 5°C) over that period. The failure occurred from a manhole cover near the base of the tank, and it is possible that a fatigue crack there grew to the point of criticality. The hoop stress is greatest near the base of a filled cylindrical tank. The tank had only been filled to capacity eight times since it was built a few years previously, putting the walls under an intermittent, cyclical load.
An inquiry after the disaster revealed that Arthur Jell, who oversaw the construction, neglected basic safety tests, such as filling the tank with water to check for leaks. When filled with molasses, the tank leaked so badly that it was painted brown to hide the leaks. Local residents collected leaked molasses for their homes

Summary and my opinion:

The Boston Molasses Disaster is a typical example of engineers not doing their duties properly. Even though the exact cause of the disaster is still unknown, but almost all fingers directly point to the people who were responsible
