Yeah, fires are rare but deadly. Building codes for materials and escape routes, fire alarms and similar are preventive measures.

For instance, where I live there's a rule for houses that all rooms where people might sleep in must have a window big enough to allow a person to escape. Of course, unless you're interested in building a house, you'll never know about this rule.

It's a bit like a seatbelt or an airbag. How often have you actually needed those? Perhaps never. But the day an accident happens, it could easily save your life.
