Either evacuate everyone, or send a whole bunch of people into fight the fire. When a fire breaks out, you can do one of two things. When the room is filled with Radaroaches or Raiders, equip whoever is assigned to that room with your strongest weapons and they will rapidly dispose of the problem.

For some reason, this tends to increase their happiness. Then place one dweller, two at the most, into each of the double and triple rooms. To do this take two or three of the same room at the same upgrade level and place them next to each other. Another solution is to give them a bigger workspace and make it less crowded.
