In page Fire drill:

"

The need for fire drills was recognized; monthly fire drills were implemented after the Our Lady of the Angels fire. It was found in a later study that education on fire also helped to prevent it: people started to learn more about what started fires, and what to do in the case of one starting. They were also aware of the hazards that allow a fire to start and grow. Within a year of the fire, many of the hazardous conditions such as found in Our Lady of the Angels had been eliminated in thousands of schools around the United States.[citation needed]
