Which factor is NOT typically considered a fire hazard in schools?

Empty classrooms are generally viewed as lower risk areas for fire hazards when compared to other factors. This is primarily because empty classrooms lack the potential fuel sources that can contribute to a fire. In schools, hazards are often associated with items that can easily ignite or create obstacles in case of an emergency. For instance, overloaded electrical outlets present a significant risk due to the potential for electrical fires, while cluttered hallways can impede evacuation routes, and flammable decorations increase the likelihood of fire spreading quickly. Therefore, empty classrooms do not typically pose the same level of hazard as these other factors.
