The report brings up the matter of risk analysis in urban planning. A risk analysis of the harbour area in Malmö has been carried out. The purpose is to provide basic data for decision-making concerning construction of residential areas in the harbour area.
By using qualitative risk analysis in order to identify large accidents a probabilistic quantitative risk analysis regarding the handling of sulphur dioxide and chlorodioxide have been carried out at Stora Gruvön pulp and paper plant, Grums. The results, individual risk and societal risk, have been compared to risk criterias.
This report is about how to predict the none-thermal damages from soot and hydrogen chloride on metallic surfaces and electronics. The models described are C-Fast and ’A Probabilistic Methodology For The Fire Smoke Hazard Analysis Of Electronic Equipment’. The models can only be used for special conditions and they demand some knowledge from the user.
This report deals with an evaluation study carried out on the community based accident prevention program being run by the municipal fire and rescue brigades in Landskrona and Svalöv. A major survey shows only a few results that could determine differences as statistically significant in fire safety behavior between the study group (inhabitants in Landskrona and Svalöv) and controll groups, but th
Smoke spread via ventilation systems relying on running fans or bypasses can be calculated with performance based fire safety analyses tools. The focus of this thesis work was to review existing methods for treating this problem and to further develop current analysis methods. Suggestions are also made for setting up guidelines as to what are tolerable amounts of smoke spread depending on building
The aim of this study was to create a scenario for a simulation model where the Swedish fire commanders could practice tactics, techniques and giving orders in a rescue operation. The object on which the fire scenario is created is an athletic centre in Lund called Gerdahallen. Both the computer model HAZARD and hand calculations have been used to construct a model of the fire in this building. Th
The objective of this study is to increase knowledge in Sweden, concerning elevator use in fire situations. This includes designing hardware and human strategies necessary for people and fire department in their use of fire elevators. This report addresses an important aspect in making the elevator safe to use during a fire. By using a pressurisation concept, smoke is prevented from reaching the
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.
