The report puts together existing experiences about residential sprinkler on issues as its ability to save lives in a fire, its reliability in activation and reasons for failure of fulfilling these tasks. The project also conducts a series of tests with activation of sprinkler in a room with a fire in order to record and evaluate the environment in the room after the sprinkler activated and compar
The aim of this report is to carry out a risk analysis of transportation of dangerous goods in the municipality of Borlänge as a basis for recommendations in the planning process.
This report contains identification of fire-hazards and development of fire-protection management-system in a university-building in Lund, Sweden. The identification of hazards has been done by comparing the technical fire-protection measures in the building to standards used in projecting new buildings today. Also observations for hazards within the actvities in the building has been made. The do
This report evaluates the methods used to predict smoke movement in atriums and the limits of smoke reservoirs used today. CFD-modeling is a wide spread tool for these types of calculations. The results of this project shows that the most important issue is to know what the user put in to the model. Most important of all is to know if there is a temperature gradient over the height of the atrium a
The purpose of this report was to investigate the damage caused by smoke on electronic equipment, and through this to be able to estimate the decontamination needs at Ericssons plant in Borås. The level of damage caused by the smoke is believed to be influenced by the following parameters: relative humidity, corrosion rate, time duration, temperature, deposition of soot and mainly negative halogen
This report contains an evaluation of the establish frequency for external emergency plans. The conclusions are based on case studies and poll answers. The assessment in this report is that the establish frequency has increased during 2004. Suggestions how to reach a better understanding for the subject has been given.
This report analyse the safety regarding evacuation in case of fire in a nightclub in Skellefteå, Sweden. The analysis contains 1:1 scale experiments regarding fire in clothes and CFD-simulations.
This report investigates the replacement of halon 1211 in handheld extinguishers used in combat vehicles. Four different tests have been carried out with five available agents: HFC 236fa, HFC 227ea, CO2, water mist and a extinguishing fluid. The results from the tests indicates CO2 to be the best alternative, although it is not as versatile as halon 1211.
This report contains an analysis of the work conducted by the Swedish local authorities regarding the prevention of wild land fires. The results shows that information and prohibiting of lighting fires outdoor are effective methods to reduce the number of wild land fires provided that the guide lines issued from the Swedish Rescue Services Agency (SRV) are followed. Furthermore, the web applicatio
What should an incident commander think about when he responds to marine vessel fires and what help can he/she expect to get from co-operational units? What kind of problems can be expected and what can the incident commander do to solve them? These and several more questions are answered along with ideas for the future.
The municipalities 4Yes have to present an action programme for the public sector and for the rescue service. As a base for their action programme the municipality needs a model. In the model there are two groups which have to cooperate with each other. A safety group and the public administrations and those who have an establishment that is described in the law “protection against accidents” chap
The objective of this work was to examine the impact on evacuation conditions of the road surface material in tunnel fires. The road materials were tested in a conecalorimeter and the results were then used in CFD-simulations. The simulated truck fires in the tunnel were chosen in accordance with E. Paté-Cornell’s Quasi Worst Case. The final result was that the road surface had no impact on the ev
This report intends to present a working method for the collection of data, which an incident commander can use at the scene of the accident during the rescue. This method contains both a general line of thought, as well as the use of different aids, with the purpose of facilitating the collecting of data. This should be well established with the person who performs the collection of data. Finally
This report contains CFD-simulations of a tunnel fire in a scaled down road tunnel, 1:8, with the CFD-code FDS. FDS and its different sub models are evaluated by different configurations of grid nets, the radiation model and slight changes in the material database and the results with respect to temperature and u-velocity are compared to each other. Comparisons of the gain and loss in time by usin
Part of the acts made by the Swedish government under the Tsunami disaster 2004 showed difficulties in registration, cooperation and command. To facilitate these requirements a technical system is needed. This report discusses different kinds of methods for computer support that enable a better command, cooperation and resource management. A requirement specification was made after activity modell
This report evaluates the fire safety of two adjoining facilities. These facilities have large basement systems and are connected under the ground by a long and narrow tunnel. Beneath the north-eastern facility’s basement system stretches a cable culvert trough the entire facility. This report evaluates the risk and identifies areas that need measures for a satisfying fire safety. Using literature
This report presents an evaluation of fire safety in the Swedish city of Mariefred. The buildings of the city are primarily 18th century, made of wood and closely built. A semi quantitative risk analysis method, BSIVI, was used in the inventory of fire safety. This method uses 16 parameters which are weighed against one another to specify the fire safety of each building. The different index value
This report concerns development of international standards within the field of emergency management. A main issue has been to examine if international emergency management standards should be developed, and if so, how and by whom. The research for the purpose of this report has resulted in many arguments associated with potential international emergency management standards. The main conclusion o
In the city of Trosa there is an old district of beautiful buildings of timber houses. The community of Trosa is very kind of protecting and preserve the culture heritage that the buildings reprehensive and the unique surroundings. The Community has the overarching responsibility for the safety of fire for the citizens and the buildings in the area. For each specific private house the owner has hi
In closed institutions, such as prisons, the inmates are locked up and therefore unable to perform an unassisted evacuation in case of fire. Since the assistance of the prison staff is required to escort every inmate to safety, often one at the time evacuation is a time consuming task. The report deals with the issue of whether the conditions in Swedish prisons today regarding evacuation in the ca
