In what timeframe do most school fires typically occur?

Most school fires typically occur between 8AM and 5PM due to various factors that coincide with school hours. During this timeframe, the buildings are occupied with students, staff, and various activities that can increase the likelihood of incidents, such as experiments in science classes or issues related to electrical equipment. Additionally, any fires that do occur are often noticed quickly due to the presence of staff and students, who can report the situation immediately, leading to faster response times.

In comparison, the other options reflect times when schools are generally unoccupied. Fires during those periods would be less likely to be reported promptly or even occur at all since there are usually fewer people present to accidentally ignite materials or report a fire. This makes the timeframe of 8AM to 5PM the most relevant for understanding when school-related fires are more common.
