Clear escape routes means nothing stored in communal corridors or stairs, and inside the flat a route to the front door you could follow in smoke. Testing alarms regularly matters because detection inside the flat is the first warning most residents get; a dead battery removes it. Closing doors is about fire doors doing their job: a flat entrance door with a working self-closer holds fire and smoke back from the only stair, which is why propping one open defeats the compartmentation everyone else relies on.
Safe charging earns its place on any modern list because lithium battery fires in flats have become a persistent theme in fire and rescue incident reporting, and a battery charging in a hallway blocks the escape route while it burns. Knowing the evacuation strategy means knowing whether your building is stay-put or simultaneous evacuation, what any sounders mean, and where you should end up if you have to leave.
