Evaluation of fire fighting spray nozzles when cooling hot smoke gases in a compartment fire. Computer simulations have been made concerning the fire scenario and time to reach fire control when water is applied. Total amounts of water are also calculated. Suggestions and conclusions drawn from the results are shown in the report. (Swedish)
In this report the cutting extinguisher is evaluated based on the cutting ability of carbon fibre laminate boards and the fire extinguishing ability. Laboratory tests and full scale tests have been carried out. Results from the tests, computer simulations and theories are discussed and compared. Suggestions and demands on improvement are presented.
Small overview of the computer based evacuation models Allsafe, Evacnet, Simulex, Steps and Wayout, focusing on their ability to predict evacuation time, based on comparison between full-scale evacuation experiment and simulation results. Diagrams showing processes of evacuation and deviations illustrate comparison results.
The aim of this report is to evaluate the evacuation situation for locomotion disabled people. The methods that have been used are literature research, interviews, questionnaires and experiments. Experiments are performed to measure factors that influence the egress for locomotion disabled people.
Analyses with Point Scheme Risk Analysis method for hospital wards and event tree analysis at several ward at homes for the aged in order to evaluate the agreement between the two methods.
The purpose of the report is to evaluate pilot safety in combat aircraft’s, of type JA 37 Viggen and type JAS 39 Gripen, exposed to the worst scenario of fire. Focus is on the performance of the canopy of the cockpit. The method used involves small-scale laboratory tests as well as a full-scale test with a Viggen in a pool fire. The conclusion is that the pilot in a Viggen has to be evacuated with
This report investigates problems concerning the use of clean agents in a low-temperature environment, i. e. temperatures below the boiling-point of the agent. Three commercially available agents have been included in the tests: HFC-227ea, HFC-236fa and FS49C2. The results from the tests show that the use of an agent should be avoided at temperatures below its boiling point, although some fire-e
The risk of smoke and fire spread for three ventilation system in an office building in Stockholm has been analyzed. The building was built in 1994 in accordance with former regulations. The analyzes are made performance based with computer simulations. The following ventilationsystems are analyzed: elevator shaft, office, rooms for technical support. The system serving office fulfills the regulat
The aim of this project was to develop a model that can be used during fire inspections to measure the quality of the fire safety in a building. The model was created by using method for Multiple Attribute Decision Making (MADM). Ten factors were identified, each of them contributing to the total fire safety in a building. Each factor was given a weight to specifiy its importance to the fire safet
A detailed flammability evaluation of different materials used in the nuclear power industry is presented as an example of how important are physical observation and detailed analysis in the interpretation of test data. The objective is to provide different criteria that could allow the use of standard test data in fire modeling. So far most fire test data has only been used as an element for rank
This report performs a risk analysis of AB Elektrokoppar in Helsingborg with consequence analysis of a few hazards. Theoretical background about risk analysis is given by IEC standards.
This report is an attempt to make a modern Rescue Services Plan that can be used in the education at the Swedish Rescue Service Agency in Rosersberg. The plan will be only temporary because of the ongoing reformation of the Rescue Services Act. A modern plan should contain activities controlled by objectives aiming at improving the safety in the society. The plan is based on the term Protection Ag
A proposal of how the pre-planning process for the attack/contingency plans can be done with the purpose to achieve an effective collaboration between the fire department and the proprietor/building owner.
The purpose of this report is to evaluate spontaneous combustion of two vegetable binders, linseed oil and tung oil. Binders with driers are common in sheet-fed offset inks. The methods used are literature research and experimental studies. The experimental study is divided in two parts, experiments in a preheated cupeling furnace, and experiments with differential scanning calorimetry-apparatus.
This report is a risk analysis of the harbour area in Trelleborg, Sweden. The purpose is to provide basic data for decision- making concerning the harbour neighbourhood. The conclusions are based on calculations and computer simulations concerning the chemical spread in case of an incident.
This report treats the problem in training fire commanders in tactical decision making and how to do it at a low cost. Different methods and means of assistance are presented. The need of education is specified by the analyse of an accident and its components.
This report contains an evaluation of the risk index method FRIM-MAB (Fire Risk Index Method for Multistorey Apartment Buildings). All parameters of the method were given minimum grades by the author of this report in collaboration with experts from four Nordic countries in order to derive a minimum grade on the risk index for buildings with noncombustible frames. 20 apartment buildings with timbe
This report is the result of a risk analysis of fire hazards in hush houses in the Swedish air force. The results are based on computer simulations, calculations and discussions. Two main fire scenarios are evaluated and it is the worst probable scenarios. The main conclusion is that one technician will die every 20 000 year in a fire in a hush house if there is no fire brigade.
This report contains a description of the Swedish legal provisions that is relevant to reduce the firerisk in historical Swedish wooden buildings. The firestart and the characteristic firespread in these buildings are discussed. Experience from fireprevention measures and efforts from Eksjö, Jönköping, Vaxholm and Fredrikstad (Norway) are also discussed.
