The Iroquois fire prompted widespread implementation of the panic bar, first invented in the United Kingdom following the Victoria Hall disaster. Panic exit devices are now required by building codes for high-occupancy spaces, and were mass manufactured in the US following the fire by the Von Duprin company (now part of Ingersoll Rand).

A second result of the fire was the requirement that a fireproof asbestos curtain (or sheet metal screen) be raised before each performance and lowered afterward to separate the audience from the stage. (Not common practice and not code in many jurisdictions--not for every performance.)

The third result was that all doors in public buildings must open in the direction of egress, but that practice did not become national until the Collinwood School Fire of 1908.
