* Location: Rural schools might have different risk profiles than urban schools.
* Building age and construction: Older buildings with outdated electrical systems are at higher risk.
* Maintenance practices: Regular inspections and maintenance significantly reduce risk.
* Fire safety protocols: Effective fire drills and safety measures impact the likelihood of a significant fire.
* Causes of fire: Arson, accidental cooking fires, electrical malfunctions all contribute to the overall risk.
Instead of an "average chance," it's more accurate to say that school fires are relatively infrequent but do occur. Data on school fires is usually tracked by fire departments and insurance companies, often at a local or regional level, making a global average difficult to calculate and potentially misleading. You'd need to look at specific region's fire statistics for a better understanding of risk.
