Flygtvejsbredden

Flygtvejsbredden is a Danish term used in building and fire safety to describe the required clear width of an escape route or egress path within a building. The concept covers all portions of the path occupants use to evacuate during an incident, including corridors, door openings, stairs, ramps, and landings, from occupied spaces to a final exit. It is defined to ensure that people can move toward safety without bottlenecks and that the route remains unobstructed during use.

The exact width requirement is determined by national regulations and standards, and it depends on factors such as occupancy type (residential, commercial, public), the expected number of occupants, travel distance, and accessibility needs. Building designers calculate the flygtvejsbredden as part of egress design, ensuring that corridors and doors provide sufficient clear width and that the path remains continuous even when doors are opened and crowded. Compliance also involves considering residents with reduced mobility and ensuring two-way traffic where needed.

Implementation and verification are typically handled during design approval, construction, and ongoing safety inspections. Changes to use or renovations may trigger reevaluation of the flygtvejsbredden to maintain safe egress. The concept is closely related to other fire safety measures, such as emergency exits, signage, and fire separation, and it is integrated into broader safety planning and regulatory compliance.
