This lesson will not tell you where to shelter, and the reason is the point of it.
Countries genuinely differ. Some maintain public shelters and expect people to use them. Some tell people to stay in the strongest interior part of their own building. Some have detailed rules that change with the type of threat. All of these are correct where they are written, and following the wrong country's rule is worse than following none.
Find out now, from your own authority. Where is my nearest designated shelter, if my country has them? How long do I have? What does the guidance say for the building I am in?
What is general enough to say anywhere.
- Put as much structure between you and the outside as possible.
- Get away from windows and exterior walls. Glass is the main injury in most blast events.
- Interior rooms, corridors and stairwells are stronger than rooms with outside walls.
- Do not use lifts.
- Take your bag, your documents, your phone and a charger; do not spend time gathering anything else.
Know the route in the dark. Count the doors, walk it once. Lighting fails in exactly the situation you need it.
