Fire Departments and Fire HQ are buildings placed in the SNES version of SimCity.
In the SNES version
Fire Departments have a similar function to their counterparts in other SimCity versions in their use to the risk of fire. Their ability to do this decreases over an increasing radius, and through budget cuts.
After placing a certain number of Fire departments, the player will be given the opportunity to place a Fire HQ, which has an extended coverage area. This can be unlocked several times
