Proper crowd management and proper emergency exit protocol are two things that are often overlooked until it's too late. This infographic from Smart Advocate takes a look at 27 of the deadliest human stampedes from the last few hundred years. The earliest stampede featured on this infographic comes from Portugal back in 1809, in what was referred to as the Ponte das Barcas bridge collapse. On this fateful day, Portuguese citizens tried to cross a bridge as they fled from troops, and the bridge collapsed.
It's estimated that 5,000 people lost their lives from this incident. Others detailed on this infographic are tragic events like the Iroquois Theater Fire, which happened in Chicago in 1903. For a theater that was advertised as "absolutely fireproof," that turned out to be wildly inaccurate when 602 deaths occurred. Not only was it advertised as being a fireproof facility, but it turned out that the fire escapes were actually unfinished at the time of the incident.
