What contributes to extinguishing room fires faster?

When a room is on fire, the quickest way to extinguish the flames (so that it credits the "extinguish fires" objective) is to have the room filled to capacity with non-pregnant dwellers.

Powerful guns + high Perception work to reduce the amount of time that radroaches and mole rats disturb a fully-occupied room.

Given a fully-occupied room on fire, besides maintaining occupancy, are there additional factors which reduce the amount of time it takes to extinguish a room fire? Perhaps stocking the room with dwellers who have a specific high-value SPECIAL attribute?

Solution 1:

Many people have debated regarding what SPECIAL value affects extinguishing fires. This inconclusive discussion implies that Intelligence affects the rate a fire is extinguished. Apparently, the only factor that might affect extinguishing fires is the room size. Obviously, smaller rooms are easier and faster to extinguish, especially if it's loaded to capacity with dwellers. Endurance combined with level also helps in these disasters; your dwellers will last longer while putting ones out.

Solution 2:

Room level is also a factor I had a maxed out 3 wide living quarters catch fire and it took almost a whole minute to put it out. But disasters in my level 1 3 wide hospital are handle almost instantly. (My dwellers have very strong guns there.) even when I replaced two high intelligence dwellers for two nitwits things were still just as fast.

Solution 3:

In my own experience my fully expanded medical with only 2 dwellers in the room was extinguished much faster than my fully expanded kitchen that had 6 dwellers. I tried to RUSH on making food and failed ending in fire. It took them sooooooo long to put it out. Upon inspection, they are all stupid with almost no intelligence at all, whereas the medical is reliant upon high intelligence. Just my experience.
