This guide will let you know how to stop fires from burning down your base in Icarus. You have to follow the simple instructions in this guide to do so.
You will need to have a fire whacker which you get early in the game, and it will help you pull out the fires. To start a fire, you have to drop your torch and then pick up your torch back when the fire starts. After that, you will need to extinguish the fire, as shown in the image below.
When you have the fire inside your house, and everything goes on fire, you have to log out from the game.
