In the year that followed the fire, Massachusetts and other states enacted laws for public establishments banning flammable decorations and inward-swinging exit doors, and requiring exit signs to be visible at all times (meaning that the exit signs had to have independent sources of electricity, and be easily readable in even the thickest smoke). The new laws also required that revolving doors used for egress must either be flanked by at least one normal, outward-swinging door, or retrofitted to permit the individual door leaves to fold flat to permit free-flowing traffic in a panic situation, and further required that no emergency exits be chained or bolted shut in such a way as to bar escape through the doors during a panic or emergency situation. Legend holds that authorities ruled that no Boston establishment could be named "Cocoanut Grove" thereafter, but there is no evidence for this; in any event there has never been another Cocoanut Grove in Boston.
