  1. 1. Mapping of Process Hazard Analyses in Swedish Process Industries and How the Work Can Be Improved

    University essay from Lunds universitet/Riskhantering (CI)

    Author : Isabella Bergström; [2022]
    Keywords : Risk management; Qualitative risk assessment; PHA; Process safety; Seveso directive; Technology and Engineering;

    Abstract : This study aims to map how Swedish process industries use qualitative risk analyses, such as process hazard analyses (PHA), to assess risks. Beyond the Seveso legislation, which requires all facilities classified as upper tier to perform a safety report each fifth years, there are no Swedish legislation or regulations regarding how and when PHAs should be executed.

  2. 2. Comparative study of risk analysis methods from a fire safety perspective - Case study of new underground facilities at CERN

    University essay from Lunds universitet/Avdelningen för Brandteknik

    Author : Frida Olin; Erik Isaksson; [2016]
    Keywords : Risk analysis methods; design fires; event tree analysis; preliminary hazard analysis; What-if; ROGA; Gretener method; NFPA 101; comparative analysis; CERN; technical risk analysis methods; case study; LHC; HL-LHC; complex methods; simplified methods; Technology and Engineering;

    Abstract : This report has investigated which type of risk analysis methods that can be used in an early design phase in a unique facility from a time and quality perspective. Two planned underground facilities for the HL-LHC at CERN have been used as a case study. READ MORE

  3. 3. Simulating production risk at Volvo Powertrain - Developing a simulation tool for decision making

    University essay from Lunds universitet/Förpackningslogistik

    Author : Magnus Cederlund; [2014]
    Keywords : Risk Management; Supply Chain Risk Management; Fault Tree Analysis; Preliminary Hazard Analysis; Lean Production; Risk Matrix; World Class Manufacturing; Fire Safety; Volvo Powertrain; Business and Economics; Technology and Engineering;

    Abstract : How can a small fire at a subcontractor in the USA lead to a multimillion dollar loss at a Swedish telephone company, and how can a single machine breakdown lead to a complete production stop at a production company? With today logistics and production trends, where terms such as Lean Production, Six Sigma, 5S, and World Class Manufacturing are used every day, production companies are introducing streamline production facilities and supply chain where goods and raw material are delivered just in time, where buffer zones are reduced, and where suppliers are reduced to a single source. These are trends that strengthen companies’ competitiveness, but it also makes companies more vulnerable to risk events. READ MORE

  4. 4. Developing the Safety Case based SQAD-methodology to handle a risk/margin profile by integrating methods for risk assessment

    University essay from Lunds universitet/Avdelningen för Brandteknik; Lunds universitet/Riskhantering (CI); Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet; Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : Jonas Åström; [2011]
    Keywords : SQAD; Safety Case; Preliminary Hazard Analysis; Risk Marginal; Technology and Engineering;

    Abstract : The aim of this thesis is to present a proposal for an evolved SQAD (Safety/Quality Assurance and Demonstration)-methodology. SQAD is a Safety Case-based methodology with the main purpose of supplying an effective tool for organizing and demonstrating system safety. READ MORE

  5. 5. Fire safety on intercity and interregional multiple unit trains

    University essay from Lunds universitet/Avdelningen för Brandteknik; Lunds universitet/Brandingenjörsprogrammet; Lunds universitet/Avdelningen för Riskhantering och Samhällssäkerhet

    Author : Peter Kangedal; Daniel Nilsson; [2002]
    Keywords : water mist system; Fractional Effective Dose; Preliminary Hazard Analysis; interregional trains; Fire safety; intercity trains; emergency rescue cards; Technology and Engineering;

    Abstract : This study is an investigation of fire safety on intercity and interregional multiple unit trains. In the study the major fire risks are identified using a Preliminary Hazard Analysis, which is followed by an estimation of the consequences for different fires onboard trains using simulations and hand calculations.
