Description

A revolving door resists wind—but a panicked crowd can jam it. After the 1942 Cocoanut Grove fire, designs that fold flat under pressure became a safety requirement. The inventor had patented the idea decades earlier. The fire killed 492 people. The revolving door was one of several exit failures; locked, hidden, and inward-opening exits also contributed. An animated explainer from The Why Side. #RevolvingDoor #Design #Shorts
