An analysis concerning the consequences of fire at SKB’s Encapsulation Laboratory in Oskarshamn (Sweden). Evaluation of the vulnerability of components critical to the operation of the facility. Suggestions are made to improve fire safety and accessibility. (Swedish).
A quantitative deterministic risk analysis of the handling of sulphur dioxide. Calculations of consequence and safety distance have been carried out through regression analysis and simulations in CHEMS-PLUS and @Risk. Results are presented as FN-curves.
Fire safety evaluation at the Swedish Rescue Services Agency office building. Conclusions are based on a fullscale evacuation drill compared with calculations and computer simulations concerning smokefilling and evacuation. Suggestions have been made to improve the situation of evacuation today from the results and judgements made. (Swedish)
This report describes a method, how to perform a risk analysis and compere the result from it with the rescue forces capacity. It also discusses how to pre-plan your rescue operation with the results from a risk analysis as basis. (Swedish)
n this report the pilot safety, in case of an accident where an aircraft overturns and catches fire on landing, is evaluated. Laboratory tests and full scale tests have been carried out. Results from the tests, computer simulations and theories are discussed and compared. Suggestions for improvement are presented.
This report deals with flame extinguishment of liquid and solid fuels in an experiment construction widely known as Burner Cup. The fuels are heptan, methanol and PMMA. According to a theory called fire point theory developed by Rasbash also further developed by Beyler the extinguish concentration increasing when applied external flux increases. Experiments have earlier been done by Magee and Rei
This report evaluates and compares the methods in fire inspection at Malmø Fire Brigade and Copenhagen Fire Brigade. The report also examines fire safety laws and regulations and the educational differences of the fire inspectors in Malmø and Copenhagen. The investigation is a project for Malmø Fire Brigade and Copenhagen Fire Brigade in co-operation with the Department of Fire Safety Engineering
The aim in this report is to create a decision tool for fire protection investments at StoraEnso Pulp, Skutskär Mill, Building TKM. Expected Monetary Value (EMV) for damage caused by fire have been calculated from fire hazard analysis, design fire, expected damage, expected fire scenario in different parts of the buildings, probability analysis and effects of fire safety systems, and from economic
This report discusses different parameters that affect external fire spread between buildings. A comparison between different methods and regulations of determining safe separation distances between buildings is made. The importance of external flames projected from openings is investigated with regards to the amount of emitted and received radiation. Finally, areas of further research are suggest
Signals from three analouge sensors has been evaluated. The sensors are an optical sensor, a heat sensor and a multi sensor. The components of the multi sensor are an optical sensor and a heat sensor. The signals came from disturbing sources and test fires at a full scale test. The purpose is to find algorithms that filtrate some of the disturbing sources but does not delay the alarm from the test
This report is based on full-scale evacuation-experiments and it aims to present an evacuation alarm or a combination of alarms which will initiate an evacuation fast. It also shows how an existing alarm could be improved without investing in new expensive systems. 18 full-scale experiments are performed at a movie theatre in Malmö, Sweden. During these evacuations, six different alarm combination
This report investigates the heat transfer through the bulkhead exposed to an engine compartment fire. Calculations are carried out with two different computer programs to solve the one dimensional heat transfer problem. Material properties are obtained by use of cone calorimeter, computer simulations, literature studies and appraisals. Conclusions are made of the possibility to predict heat trans
The reports objective is to present a model for calculating the protective distance when ammonia disperse from a land based vehicle. The model is based on a response surface together with a user guide that makes it possible to use the response surface even when one or all of the variables in the response surface is unknown. The report is written in Swedish.
The report is a risk analysis of the hydrogen production plant at Ringhals Nuclear Power Plant, Sweden. The report also discusses potential hazards from the handling and storage of hydrogen gas. Principles of hydrogen gas detection and sensor technology are presented. A HAZOP-analysis of the plant is carried out, and recommendations of improvements based on the results of the analysis are made. Co
An inventory and analysis of extinguishing agents and systems. A quantitative analysis of the weight of the systems and of the damage on hull material for different fire scenarios. Tests have been carried out in cone calorimeter and simulations in HSLAB and FREIA:
A probabilistic riskanalysis of a railway tunnel in Örnsköldsvik, Sweden. Using societal risk showing the hazard of the system. The analysis indicates a high risk greater than recommended levels of acceptance according to international risk criteria. Furthermore proposal for hazard prevention in tunnels are made.
The purpose of this study is to evaluate the safety of people located in discotheques in case of fire. A quantitative fire riskanalysis (QRA) for three different types of discotheques is carried out. The analysis is based on performance based codes from which fire protection alternatives are analysed. The results of the quantitative fire riskanalysis are described as risk profiles and average risk
A serie of ten full scale fire scenerios has been analysed in a compartment with and without residentiual sprinkler. The production of carbon monoxide, carbon dioxide and oxygen was measered in two different heights in the compartment during the tests. (Swedish)
A waterflow measurement device has been developed with which it will be possible to simultaeously study both amount of water applied and its effect temperature, during firefighting in an firetraining house. Major part of the applied water is used to cool the surface of the non-flaming fuel. Short showers with the nozzle does not seem to be as effective as the longer showers, regarding both time to
