The number of metro systems around the world is increasing rapidly. With an increase of metro systems, the number of deep underground metro stations will probably also grow. In Sweden, this is exemplified with station Sofia at the extension of the Stockholm metro system, which is planned to be situated around 100 meters below ground. […]
Arson in schools, especially by young arsonists, has been considered a problem in Sweden since at least the turn of the century. A major research program was carried out in 2008-2012 to investigate this problem and make recommendations for action. During the course of the research program, the number of arson in schools decreased, but […]
Phytic acid is a naturally occurring compound found in the foods we eat, e.g. in nuts and cereals. It is the most important storage of phosphorus in plants, and phytic acid contains 28% phosphorus. Phosphorous compounds have proven to be effective flame retardants for cellulose-based materials such as wood and cotton, so phytic acid has […]
Demographic changes in the population of several countries call into question the current basis for evacuation sizing, as design values are often based on experiments from the late 20th century. Therefore, a new strategy has been developed describing how people’s movements in an evacuation should be described. The starting point is to determine person flows […]
The electrical environment of our buildings including our homes is changing. One example is local electricity production, where photovoltaic installations are becoming increasingly popular. Such electricity generation also entails changes in other parts of the electrical infrastructure of buildings, such as DC networks and, in some cases, energy storage in battery systems. What are the […]
The project has focused on the risks of dust explosions and any fire that may arise in various manufacturing processes where metal dust is formed. The work has included studying available statistics to get a better picture of frequency, cause and effect in connection with explosions that occurred, but also to study some real incidents […]
In Sweden the responsibility for damage to the environment at a fire incident is increasingly focussing on the responders. Most incident response personnel do not have the training and expertise to understand the environmental consequences of their field operations. The Fire Impact tool was developed for training responders about the environmental impacts resulting from their […]
At the industrial workplace, conflicts may occur between production and fire safety solutions, sometimes to the point where fire protective routines or installations are bypassed. A common answer to such issues is to strengthen administrative barriers such as rules, safety information and training. However, in an industrial organization where resources are already strained, even more […]
Loose furnishings, such as upholstered furniture, mattresses and textiles, are very important for the early stages of fires. Such products can be easily ignited, contribute to rapid spread of fire and produce a lot of smoke and heat when they burn. This limits the time and opportunity for evacuation and fire rescue. Fire safety and […]
Significant differences in the risk of death from fire have been shown to exist in regards to different age groups, socio-economic groups and geographi-cal areas. One group that repeatedly is shown to be particularly at risk is older people, a group that also constitutes the age group that percentagewise is increasing the most in society […]
