# Fires Fires are arguably the most dangerous atmospheric upset that can occur on the station. They often make high-pressure and high-temperature gasses, which can quickly spread throughout the station if firelocks or doors are opened carelessly, even if only for a moment. If people are caught in a fire, they can quickly become incapacitated, die, and even ash, rendering them unrevivable. ## Combating Fires The key elements of a fire are fuel and oxygen. Removing any of these two elements will extinguish the fire. For example, fires that have no oxygen flowing to them will slowly snuff themselves out, and fires that have no fuel will also extinguish themselves. Exposing the fire to space will extinguish it, as all the gas will simply be spaced.

Try to isolate the area and scrub the gasses out as quickly as possible. - [bold]Prevent the spread of gasses using a holofan projector.[/bold] Letting gasses through a firelock can make other rooms dangerous, even for a moment. This increases the number of rooms you have to fix.
