Uncertainty in the assessment of BLEVE risk in process plants and in transportation / Casal Fabrega, Joaquim (speaker) (UPC Universitat Politècnica de Catalunya)
BLEVE explosions keep occurring from time to time in process plants, storage and transport by road or rail. Concerning the materials, the highest contribution is that from LPG and water, but many other liquids can also be involved; depending on their properties, the explosion can be followed by a fireball or a toxic cloud. Although diverse models and methodologies have been proposed to calculate the mechanical effects from a BLEVE, this prediction is subjected to a series of uncertainties: pressure inside the vessel, amount of material contained, contributions to the energy released (vapor expansion, liquid flashing), fraction of energy released devoted to create overpressure.

Practical approaches to QRA in fire protection engineering. / Tofilo, Piotr (speaker)
The goal of this presentation is to discuss QRA methods in the area of fire engineering from own engineering experience and from a wider fire community and literature. QRA usually involves issues such as input data and scenarios, models, uncertainty, sampling techniques and assessment criteria. [...]

A Scale of Risk: A Multidimensional Evaluation and Comparison of Risks / Gardoni, Paolo (speaker) (Department of Civil and Environmental Engineering, University of Illinois at Urbana-Champaign, USA)
This presentation offers a conceptual framework for ranking the relative gravity of diverse risks. The framework identifies the different aspects including moral considerations that should inform the evaluation and comparison of diverse risks and in turn shape the decisions for risk mitigation.

Treatment of uncertainty in fire safety risk analysis / Frantzich, Håkan (speaker) (Lund University)
Fire safety engineering is still a rather young engineering discipline which is under a rapid development. Historically, fire safety issues have been treated by prescriptive means based on lessons learned from incidents that had occurred. [...]

Experiments and Modeling in Support of Nuclear Power Plant Probabilistic Risk Assessment in the USA / McGrattan, Kevin (speaker) (NIST)
For the past two decades, the Fire Research Division at the National Institute of Standards and Technology (NIST) has performed fire experiments and numerical modeling to support the transition by the US Nuclear Regulatory Commission to a performance-based, risk informed approach to fire safety. The presentation will briefly describe the various projects, including fire model verification and validation, cable fires, compartment fire dynamics, protective cable coatings, incipient fire detection, high energy arc faults, and uncertainty analysis..

Fire Probabilistic Risk Assessment in the US Nuclear Power Industry / Floyd, Jason (speaker) (Jensen-Hughes)
Fire protection in US nuclear power plants was long regulated under a set of federal regulations called 10 CFR 50.48 Appendix R that prescribed fire protection measures. In 2001, the National Fire Protection Association issued NFPA 805, a performance based standard for fire protection at nuclear power plants. [...]

ESS fire- and explosion safety programme - deterministic and probabilistic conditions – case study on acceptance criteria to open smoke hatches in the instrument building. / Jörud, Fredrik (speaker) (European Spallation Source)
A number of Swedish acts and ordinances give the basic requirements of facility safety. None of these are tailored for ESS, hence interpretation is required for appropriate application. [...]

From Risk Analysis to Decision Support / Faber, Michael Havbro (speaker) (Aalborg University, Denmark)
The role and character of risk analysis and risk assessments have undergone significant changes over the last 3-4 decades. From being mainly a procedural instrument to document that nominal risks associated with a given decision are under control and compliant with specified targets, risk analysis and risk assessments are increasingly utilized for optimizing or ranking decisions based on information on the actual risks they imply.

Citizen Science: Benefitting Science and Citizens / Land-Zandstra, Anne (speaker) (Universiteit Leiden)
Citizen science - projects where the general public can get involved in "real" science - has gained enormous popularity in recent years. Scientists are excited to be able to benefit from the help of tens, hundreds, or even thousands of people. [...]
