Should one of your caves have power conduits running through all the area and completely sealed with roof, they could be used to spread the fire by closing the caves with walls and then simply shoot at a conduit to ignite. Infestations are difficult to clear, especially when spread through multiple (mined out) caves.ДЄn effective method is to equip a colonist with an incendiary launcher or molotov cocktails and attack the hives one at a time.

But then again, you could just execute them all. Capture the pawns you want, and let the rest flee. Once their heatstroke reaches 0.7 severity (70% percent, extreme heatstroke), open the doors and put out the fires. The raiders will drop like flies after a while. When enemies arrive, wait until all of them have entered the killbox, then light the barricades on fire with incendiary weapons. Near it, build a shelf with incendiary weapons for convenience. Wooden barricades should the be constructed inside the detachment. Additionally, add stone doors at the end of the corridor, but hold them open for now. In an killbox corridor, a small detachment with doors connecting to the outside should be constructed.

Objects with 0% flammability can't catch fire.ДЇire can be utilized as a weapon or tool to counter things like infestations or to help capture enemy pawns. The size of the fire depends on the flammability of the material. The damage taken value is the same for everything. Objects and structures on fire will take damage to their hit points over time. To prevent pawns from succumbing to the heat in an enclosed room, simply either remove some of the roof or hold one of the doors open, and then tend to the fire. Pawns trying to put out the fire may collapse from heatstroke. If the fire is not extinguished eventually a pawn will become incapacitated and burn until deathДЄt higher temperatures (above ~235C/455F/508K), flammables can spontaneously ignite, and an orange haze effect will appear. Heat damage has no armor penetration and is therefore easily affected by heat resisting apparel. While on fire a pawn will receive 2 heat damage per second regardless of the flame size. They cannot be controlled in this panic state. Also note that pawns on fire can also spread fire which can lead to a cascade effect. If this occurs, the player can prioritize a different colonist to attempt to put out the flames of their burning comrade.

They may also wander into unsafe open areas where they might be vulnerable to attacks. Pawns on fire will become momentarily disabled by panic and will attempt to extinguish the fire by putting it themselves or finding a water body. Another key step to preventing fire is to use non-flammable materials for walls. Place firebreaks outside of colony perimeter walls and around other important structures. Firebreaks are non-flammable flooring, typically concrete, with a minimum width of three tiles. To make them fight fires outside of this area, use the 'Expand home area' tool in the Zone/Area section of the Architect menu, or draft them and place them next to the fire you wish them to extinguish.ДЄ good way to prevent fire from spreading is by using firebreaks. Colonists capable of firefighting will only fight fires in your Home area.

Fire may spread far and wide if left unchecked. It spreads via embers that travel up to two tiles and will start another fire if it lands on something flammable. Fire is capable of destroying crops, resources, structures, and can injure or kill pawns.
