Larger buildings are frequently divided into so-called fire compartments, which are separated by fire-resistant walls and ceilings. In the event of a fire, these elements offer complete fire and smoke resistance based on the prescribed fire resistance.
In all regulations, special attention is always devoted to the vertical connections that can become a serious risk in case of fire.
Vertical connections are ordinary stairs, lift shafts or installation shafts. Generally, the provisions for fire compartments are aimed at limiting the potential spread of fire through these building elements.
In new constructions, a fire compartment needs to be integrated directly into the building structure. Fire compartments can consist of a single room or a string of rooms.
When a fire breaks out inside a compartment, the sealed nature of the area can compartmentalize the fire, preventing its spread to other areas. In case of a fire outside the compartment, it can remain sealed off and can potentially even protect the objects inside.
