Airplane Evacuations

“Evacuating a plane can be quite perilous—whether you're a real passenger or a volunteer in a certification test. A government study of airline evacuation drills in the 1970s and 1980s found that almost 5 percent of the participants get hurt.“ – Slate
Who would have thought that 1 out of 20 passengers could be injured just getting off an airplane during an emergency evacuation? But if you think about, getting off a crowded airplane is never easy even during normal days. Now add darkness, smoke, panicking people, luggage everywhere, inflated life vests, and you have a recipe for chaos.

You also may not have much time. The FAA requires that the airplane's maximum capacity of passengers and crewmembers can evacuate the plane in less than 90 seconds—the time it takes a fire to engulf a standard cabin.

Can you guess the main cause of injury during plane evacuations?

It is the inflatable slide that can be up to 26 feet off the ground. The most common injury is “slide burn” when bare skin is scraped raw going down the slide. The next danger is “hitting” the ground when the “slow down” strips fail at the base of the slide. People have broken ankles and legs from reaching the ground too fast. The worst injury occurred when a volunteer tester fell off the top of the slide and hit the pavement head first.

All the above points are occurred when a Paris flight to Toronto made a hard emergency landing, caught fire and managed to evacuate everyone in less than two minutes, 75% got off within 52 seconds

Bags were “flying down” from the overhead bins, and the plane was coming apart…. “Stewardesses started pushing everyone out,”

People near the fire at the rear of the plane panicked.

“People were tripping over each other, climbing over the seats to get to the
exit”

At a front door there was no chute to slide down and the drop was about 12 feet. A second door had a damaged chute but it worked.

“I jumped and fell onto some people,” a passenger said, “Some people broke their
arms or legs.”

Bottom Line

Stay calm and be careful when evacuating a plane and you should be OK.

“There is this myth out there that says if you’re involved in a catastrophic aircraft accident the odds [of survival] are extremely low. That’s inaccurate. The odds are extremely high,” said Mark Rosenker, the acting chairman of the U.S. National Transportation Safety Board.
