A bookkeeper on the 8th floor was able to warn employees on the 10th floor via telephone, but there was no audible alarm and no way to contact staff on the 9th floor. According to survivor Yetta Lubitz, the first warning of the fire on the 9th floor arrived at the same time as the fire itself. Although the floor had a number of exits, including two freight elevators, a fire escape, and stairways down to Greene Street and Washington Place, flames prevented workers from descending the Greene Street stairway, and the door to the Washington Place stairway was locked to prevent theft by the workers; the locked doors allowed managers to check the women's purses. The foreman who held the stairway door key had already escaped by another route. Dozens of employees escaped the fire by going up the Greene Street stairway to the roof. Other survivors were able to jam themselves into the elevators while they continued to operate.
