Within three minutes, the Greene Street stairway became unusable in both directions. Terrified employees crowded onto the single exterior fire escape – which city officials had allowed Asch to erect instead of the required third staircase – a flimsy and poorly anchored iron structure that may have been broken before the fire. It soon twisted and collapsed from the heat and overload, spilling about 20 victims nearly to their deaths on the concrete pavement below. The remainder waited until smoke and fire overcame them.
