When tragedy befalls children, we yearn for lessons learned that lead to meaningful reforms. That was the case after the fire at Our Lady of the Angels on the West Side. Chicago overhauled its fire code. Exit signs were made brighter. Schools were required to conduct monthly fire drills. They had to ensure that fire alarm systems were directly tied to the Fire Department. Across the country, nearly 70 percent of schools revamped fire safety because of what had happened at Our Lady of the Angels.
