Fire safety concept in competition phase: optimisation of evacuation capacity

The fire safety concept for the Beursschouwburg focuses on increasing the capacity and concurrency in the use of the halls, with a particular focus on evacuating visitors in different halls.

The design is based on the applicable laws and regulations, including the Royal Decree (RD) Basic Fire Safety Standards, the Brussels legislation for theatres, the General Regulations on Labour Protection (ARAB) and the Codex Welzijn op het Werk.

Evacuation and fire safety: the inner street as a crucial evacuation space

In the design, the internal street, which acts as the main stairwell and evacuation space, is strategically used to ensure the safety of visitors. This space will be strictly fireproof separated from other parts of the building. A smoke evacuation system (RWA) will ensure continuous safe and free passage in case of emergency.

The lift in the inner street will become part of the evacuation space. By separating the lift from the other compartments, it directly contributes to the overall safety of the inner street.

Emergency plan

The large occupancy of the Beursschouwburg requires escape routes that are carefully checked for their capacity. These will be optimised and adapted to contemporary standards, with clear signage and strategic placement of emergency exits.
Together with the fire brigade and the Beursschouwburg itself, additional measures will be worked out to speed up evacuation. All these measures will contribute to efficient evacuation and improve the overall safety of the building.

This fire safety concept allows the Beursschouwburg to maximise the use of its halls without compromising the safety of visitors and staff.

Fire compartmentation and fire detection

In addition to the focus on the internal street, compartments are used in the rest of the building. The floors will be compartmentalised separately, creating smaller units of up to 200m². Sub-compartments are created for areas with specific functions, such as kitchens, rubbish storage and halls, to limit the spread of fire.

A general fire detection system combined with the aforementioned measures helps to speed up evacuation.

Safety in the foyers and stairs

A particular concern within the fire safety concept is the passage from the stairs leading to the Silver Hall, through the foyers to the Golden and Bronze Halls. To ensure the safety of the inner street as a general evacuation route, we take three important precautions in these foyers:

  • Fire reaction class of materials: materials with the highest possible fire reaction classes are chosen.
  • Sub-compartmentation of the stairwell: The stairwell on the higher floors is sub-compartmented so that a fire in the White Foyer does not compromise the safety of evacuation to the Silver Hall.
  • Organisational measures: No activities will take place in the foyers when events take place in the rooms that need to be evacuated through these foyers.
