Evacuation through inward opening doors : Literature study and evacuation experiments
(2023)- Abstract (Swedish)
- Evacuation through inward opening doors can present challenges for safe egress during fire incidents. This study comprehensively investigates the dynamics and challenges associated with this type of evacuation, aiming to provide valuable insights for fire safety design. A literature review and experimental evacuation experiments were conducted. The experiments compare occupant movement towards and through inward opening doors with outward opening doors. Crucial parameters such as occupant density, door opening force, presence of a corridor (flow construction) and walking distance, were examined.
The findings highlight that evacuating through inward opening doors is slower during the initial stage of egress due to the increased...

This study comprehensively investigates the dynamics and challenges associated with this type of evacuation, aiming to provide valuable insights for fire safety design. A literature review and experimental evacuation experiments were conducted. The experiments compare occupant movement towards and through inward opening doors with outward opening doors. Crucial parameters such as occupant density, door opening force, presence of a corridor (flow construction) and walking distance, were examined.
The findings highlight that evacuating through inward opening doors is slower during the initial stage of egress due to the increased interactions required between evacuees. Further, high occupant densities near the door can obstruct door opening, emphasizing the importance of managing occupant density. The presence of a corridor, or other flow congestion in front of the door slightly reduces people flow. In contrast, it promotes organized group formation, facilitating door opening. Increased walking distance to the door reduces occupant density for people reaching the door first, easing the door opening process. The number of people evacuating through the door does not significantly impact door opening, supporting the importance of managing occupant density instead. The study concludes that key parameters when safeguarding evacuation through inward opening doors include appropriate door fittings, low occupant density near the door, and fast door opening maneuvers, even for larger numbers of people.
