Prevention in a block of flats lives in unglamorous places: secure bin stores kept away from the building line, locked electrical intake and meter cupboards, no storage or battery charging in corridors, and an arson-aware approach to access control. Detection and warning looks different from a workplace: many general-needs blocks with a stay-put strategy deliberately have no communal alarm, relying instead on detection inside each flat and automatic smoke control on the landings, a distinction the stay-put glossary entry explains.
Means of escape is the protected stair and everything that keeps it usable: self-closing flat entrance doors, fire doors on risers and stores, emergency lighting, signage where the layout demands it and nothing stored on the route. In most purpose-built blocks there is a single stair, so means of escape and containment are two sides of the same wall: the escape route only works because the construction around it holds smoke back.
