Boston Molasses Disaster (1919)
A molasses tank in Boston's North End was given a nominal inspection by its builder rather than a city engineer, then burst on January 15, 1919, killing 21 people. The tank had not undergone full structural review before it was put to use.
Sixteen lawsuits followed; the tank's builder paid settlements.
The disaster pushed building and inspection standards, but the lesson lingers that a single sign-off is not a full safety review.
Like that ill-checked tank, a single Philadelphia business license is one approval, not proof the eatery is ready to serve or structurally sound.
