Abstract [en]

With the purpose to increase the knowledge on human behaviour when evacuating along elevated platforms, an experiment was carried out at the subway station of Skarpnäck, Stockholm, in October 2016. The overall project objective was to develop basic data for guidelines regarding fire safety design concerning evacuation along elevated platforms. The experiment was designed as a group experiment divided into five different scenarios. In total, 111 persons of mixed gender and age participated. The results from the experiment show that the flow rate along the elevated platform decreased as the walkway was getting narrower. It could also be seen that along the first half of the walkway, where a train was located on the rail track next to the elevated platform, the flow rate was higher and the width of the walkway was used to a lager extent compared to the second half of the walkway where the platform was open to the track area. One of three wheelchair users who participated in the experiment expressed discomfort caused by the height and the width of the walkway and nearly half of the participants experienced problems with passing others walking slower than themselves.

Funding details: Trafikverket; Funding text 1: The project was initiated and financed by the Swedish Transport Administration . The study was a cooperation between RISE Research Institutes of Sweden and Brandskyddslaget . RISE was responsible for planning, performing and evaluating the experiment. This work has been carried out as a grant research project and no agreements existed that could have influenced the project results. The Swedish Transport Administration – being both the initiator of the project as well as one of the end users – has however participated in early experiment discussions.; Funding text 2: This study was a part of the project “Elevated platforms in railway tunnels”. The project was a cooperation between RISE Research Institutes of Sweden and Brandskyddslaget. The authors would like to thank The Swedish Transport Administration for initiating and financing this project and thereby making it possible to increase the knowledge within this research area. The experiment was performed with support from MTR Nordic AB (MTR), Stockholm Public Transport (SL) and Stockholm Greater Fire Brigade (SSBF). The authors would like to thank these organisations that made the full-scale tests possible to perform. Karl Fridolf, former colleague to the authors, was the initiator of the project, performed the literature study and performed a pilot experiment that formed a base for the full-scale tests. Karl Fridolf should therefore be especially thanked for his contribution. Many others have also helped during the preparation or performance of the full-scale tests and special thanks should be directed to fire engineer Per Rohlén who, as always, provided the authors with valuable photos and thoughts.

Abstract [en]

New materials and designs enter the market every day. They have a great market potential needed for many applications. The future market for development and production of fibre reinforced composite materials (lightweight materials) is very promising, not only within advanced application such as aeronautics, but also in maritime industries, on modern ship vessels and in railway vehicles. As a result of this it is important to know the material properties and fire behaviour in order to ensure a high safety level [1].Materials are tested as “new” and un-aged, which means testing is performed on newly produced products and materials. Very little research has been done regarding fire performance of materials after aging [5].Accelerated ageing can be performed with different aspects and in numerous ways. One type of these can be called weathering and there are mainly four basic types of this ageing used for products and materials. They are: thermal ageing, exposure of high temperature during a selected time; moisture ageing, exposure of water or moisture; UV exposure, and radiation ageing. [5]These types of ageing can be performed in many ways and combinations. For example, thermal ageing can be performed at a selected temperature and time. But it can also be one part of a climate cycling were you have fixed periods with temperature exposure followed by moisture exposure and UV exposure. This cycle can be repeated a numerus of times [7].The degradation of composite materials and change in properties is slow at room temperature. It gets faster with increased temperature. Accelerated ageing is an intentional way to expose materials and products to a proper simulation of long-term usage. Within a few days, weeks or months the damage and degradation of the materials can occur, which normally would be after years in normal climate and after normal usage. Accelerated ageing can cause the material properties to get worse, and an undesirable loss of functionality may be evolved [4].The behavior and material properties of fibre reinforced composites, after exposure of aggressive environmental conditions, shows changes, compared to new materials. After exposure of moisture, the fibres may result in damage and the material structure might be changed. After exposure of moisture and high temperature the durability of the composite is reduced [2].The Arrhenius Rate Law of accelerated ageing can be used to correlate the time in ageing climate. A generalization, supported by the Arrhenius Rate Laws, is that for a reaction in room temperature, the reaction rate doubles every 10°C increase in temperature [6].The objective of this work is to gather the most common methods to perform accelerated ageing, to see the variations between the methods and within the method.

We are very proud to present the abstracts of 62 Nordic and international contributions

in the present book of abstracts. The work demonstrates a significant scientific depth

and societal relevance. The conference is a response to the extensive interest in the

areas of fire and safety engineering in the Nordic countries in the past decades. As the

programme and the abstracts show, the NFSD follow up on challenges with respect to

safety dealing with aspects of fire and actions of the rescue service as well as human

behavior and risk management. This year there is a special focus on fire safe furniture

and the intervention of the rescue service.
