A purpose built block of flats would normally incorporate a 'stay put' strategy whereby only residents from flats directly affected by fire or smoke need evacuate. Residents in other unaffected flats should be protected by the structure ofthe building, including the front doors of individual flats and other fire doors around the building. Those other residents should therefore be able to 'stay put' during afire in their building unless otherwise directed by the fire brigade, and in many cases may not even be aware of a fire elsewhere in the building.
