"You might think that everything would have changed for the chemicals industry on April 16, 1947. That was the day of the Texas City Disaster, the worst industrial accident in U.S. history.

The ship sparked a chain reaction of blasts at chemical facilities onshore, creating what a newsreel at the time called "a holocaust that baffles description."
Or you might think everything would have changed on Dec. 3, 1984.
