Many patrons attempted to exit through the main entrance, the same way they had entered. The building's main entrance was a single revolving door, which was rendered useless as the crowd stampeded in panic. Bodies piled up behind both sides of the revolving door, jamming it until it broke. The oxygen-hungry fire then leaped through the breach, incinerating whoever was left alive in the pile. Firemen had to douse the flames to approach the door. Later, after fire laws had tightened, it would become illegal to have only one revolving door as a main entrance without being flanked by outward opening doors with panic bar openers attached, or have the revolving doors set up so that the doors could fold against themselves in emergency situations.
