First documented deaths due to “global warming”, the tank was filled on a cold winter’s day then came apart due to a warm day in January.
Very sharp of you Sparky1776 (carbon dioxide no less):
That January's relatively balmy, 40-degree Fahrenheit weather may have increased pressure as carbon dioxide built up inside. Before the rupture, the molasses inside the tank was likely 5 degrees Celsius warmer than the surrounding air, thanks to a fresh shipment of syrup from the Caribbean. The higher temperature may have helped the molasses spread over the Boston waterfront at such an alarming pace. http://vaviper.blogspot.com/2017/01/jan-15-1919-bostons-23-million-gallon.html
