Should you open or close a door if the room is on fire?

If a room is on fire, you should close the door behind you as you leave, if it is safe to do so. Closing the door helps to contain the fire and limit the spread of smoke and flames, providing more time for evacuation and potentially protecting other areas of the building. If you are still inside, try to escape through a different exit rather than opening the door, as opening it may introduce oxygen and worsen the fire. Always prioritize personal safety and follow emergency procedures.
