<onlyinclude>[[Fire]] is a destructive force capable of destroying plants, buildings, and pawns alike. It spreads via embers that travel up to two tiles and will start another fire if it lands on something [[flammable]]. Fire may spread far and wide if left unchecked. Fire also causes a massive surge of [[temperature|heat]] when indoors. While inherently dangerous, fire can be used as a weapon or tool.

[[Colonist]]s capable of [[Work#Firefight|firefighting]] will only fight fires in your [[Home area]].</onlyinclude>

== Sources of fire ==
{{stub|section=1}}
* Temperatures above {{Temperature|235}} will ignite flammable items and structures.
* Created from [[molotov cocktail]]s, [[incendiary launcher]]s, [[phoenix armor]], and [[incendiary shell]]s/[[IED incendiary trap|IED traps]].
* Humanoid [[raider]]s may light your colony's objects on fire. If players actively engage raiders they seem to fight instead...
* [[Boomalope]]s and [[boomrat]]s will cause fire on [[death]].
* [[Weather|Lightning]] will cause fire. Rain will quickly put it out, but Dry Thunderstorms and [[Events#Flashstorm|Flashstorm]] won't have that.
* The event [[Events#Zzztt...|Zzztt...]] will cause fire.

== As a hazard ==
Fire is capable of destroying crops, resources, structures, and can injure/kill pawns. To make colonists 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.

=== Basic prevention ===
A good way to prevent fire from spreading is by using firebreaks. Firebreaks are non-flammable [[floor]]ing, typically [[concrete]], with a minimum width of three tiles. Place firebreaks outside of colony perimeter walls and around other important structures. Another key step to preventing fire is to use non-flammable materials for walls.

=== Pawns ===
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. They may also wander into unsafe open areas where they might be vulnerable to attacks. If this occurs, the player can prioritize a different colonist to attempt to put out the flames of their burning comrade. Also note that pawns on fire can also spread fire which can lead to a cascade effect. They cannot be controlled in this panic state.

While on fire a pawn will receive 2 heat damage per second regardless of the flame size. Heat damage has no armor penetration and is therefore easily affected by heat resisting apparel. If the fire is not extinguished eventually a pawn will become [[Injury#Shock|incapacitated]] and burn until death

=== Interiors ===
At higher temperatures (above ~235C/455F/508K), flammables can spontaneously ignite, and an orange haze effect will appear. Pawns trying to put out the fire may collapse from [[Injury#Heatstroke|heatstroke]]. 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.

=== Objects ===
Objects and structures on fire will take damage to their hit points over time. The damage taken value is the same for everything. The size of the fire depends on the [[flammability]] of the material. Objects with 0% flammability can't catch fire.

== As a tool or weapon ==
Fire can be utilized as a weapon or tool to counter things like infestations or to help capture enemy pawns.

=== Pawn Capture ===
In an killbox corridor, a small side area with doors connecting to the outside should be constructed. Additionally, add stone doors at the end of the corridor, but hold them open for now. Wooden barricades should then be constructed inside this area, this is your "fuel". Nearby, build a shelf with incendiary weapons for convenience. When enemies arrive, wait until all of them have entered the "killbox", then light the barricades on fire with incendiary weapons. Then, close the two doors at the end. The raiders will drop like flies after a while. Once their [[heatstroke]] reaches 0.7 severity (70% percent, extreme heatstroke), open the doors and put out the fires. Capture the pawns you want, and then either execute the remainder or let them flee once they regain consciousness.

=== Countermeasure against infestations ===
[[Events#Infestations|Infestations]] are difficult to clear, especially when spread through multiple (mined out) caves.

An effective method is to equip a colonist with an incendiary launcher or molotov cocktails and attack the [[hive]]s one at a time.

Should one of your caves have [[power conduit]]s 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. [[Insectoids]] will collapse and eventually die of [[Health#Cold and Heat Injuries|burn]]s or [[Injury#heatstroke|heatstroke]], hives will ignite if the temperature gets high enough for spontaneous combustion.

=== Flora raze ===
A faster alternative to "Cut plants" to clear areas from vegetation that provides a tactical defense as it takes any possible cover object away from enemies. Equip  an [[incendiary launcher]] or [[molotov cocktail]] and target to attack the desired area. The fire will spread rapidly in all directions, so the player must ensure there are no flammables near unintended sections. [[Rain]] will extinguish fire on unroofed areas.

== Firefighting ==
Firefighting is most often accomplished by [[colonist]]s "stomping" on the fire until it goes out completely. Another method of extinguishing fire is by deploying [[firefoam popper]]s that when triggered by flames will explode to blanket the area with fire-suppressing foam.

You can also blow fire out with an explosion like that produced by a grenade (draft a colonist who has grenades, target the fire). 

=== Colonist firefighting behavior ===
By default, all colonists not currently working on another job will go to extinguish a fire, if capable, ''only'' if the fire is within a designated '''[[Zone/Area#Home_area|home area]]''' and the colonists' allowed area. Unlike other tasks that get reserved, colonists do not lock out each other from fighting the same fire and may work together to extinguish it quicker.

It is worth mentioning again that colonists only fight fires within a home area. Outside the home area, colonists will just ignore the fires and carry on with their duties. To fight fires outside of a home area or to fight fires in a coordinated manner, draft the colonists and place them NEXT to the fire. They will fight any adjacent fires and you can better move your colonists to strategically attack it.

Colonists can catch on fire while firefighting but will usually manage to put out the fire. If instead they become downed, the fire will consume them unless another colonist comes to put them out.

Pyromaniacs will never extinguish fires and in fact may sometimes start them.

=== Firefoam poppers ===
{{main|Firefoam popper}}
After their initial construction, firefoam poppers can be uninstalled and stored. Reinstalling them later—near a small-to-moderately sized field of fire—and manually detonating them allows a single pawn to quickly and safely complete a dangerous task that could otherwise occupy several pawns for many danger-filled hours.   

=== Rain event ===
{{stub|section=1|reason=Specific triggers, chances, durations etc.}}
Extremely large and long lasting fires will force a [[weather|rain]] event. Sufficient rain will gradually extinguish unroofed fires, and this event may even, eventually, control large wildfires.  

Some fires after rain event are possible. Rain event may happen without extra delay between them.
