I am living in a flat (6th floor). There is a lot of smoke coming from under my door, I don't have my phone, what should I do?
If you are in a situation where you are in a flat on the 6th floor and there is smoke coming from under your door and you do not have your phone, there are a few steps you should take:

1. Check the door for heat: Before opening the door, feel the door with the back of your hand to see if it is hot. If it is hot, do not open the door as it may be dangerous.
2. Alert others: If possible, shout or make noise to alert others in the building or nearby that you need help.
3. Use a wet cloth: Wet a cloth and cover your nose and mouth to protect yourself from inhaling smoke.
4. Open the window: Open a window to let fresh air in and to signal for help.
5. Wait for help: Stay near the window and continue to shout for help until someone arrives to assist you.

If you are unable to open the door or are trapped, move away from the door and towards the window. If you have a balcony, move to the balcony and signal for help. Stay low to the ground to avoid inhaling smoke, and try to remain calm and alert. If possible, use a cloth or other material to block the gap under the door to prevent smoke from entering your room.
Is there any additional info about saving yourself from a fire in a building, or that's all?
