I would like to suggest a fire control mod. Similar to the menu in the regional menu, players can select how many trucks and what kind of trucks to respond to a fire. For example: I will have 2 engines and one ladder respond to a regular fire. (You can't really change what goes to a hazmat fire). Sending multiple trucks to a fire would help out the fire out faster, but you are tying up more apparatus, so if there is a second fire you may not have enough trucks to fulfill your assignment.
