“…To estimate incident heat flux from a flaming front, it is thus necessary to compute a view factor between the front and the target. Thermally excited soot particles represent the major source of thermal radiation from wildfire flames; hence, emissivity should be estimated with correlations found in the literature in terms of a mean absorption coefficient for soot (Lautenberger et al 2016). If the flaming front is sufficiently thick, i.e.…”

Background Wildfires have caused significant damage in Chile, with critical infrastructure being vulnerable to extreme wildfires. Aim This work describes a methodology for estimating wildfire risk that was applied to an electrical substation in the wildland–urban interface (WUI) of Valparaíso, Chile. Methods Wildfire risk is defined as the product between the probability of a wildfire reaching infrastructure at the WUI and its consequences or impacts. The former is determined with event trees combined with modelled burn probability. Wildfire consequence is considered as the ignition probability of a proxy fuel within the substation, as a function of the incident heat flux using a probit expression derived from experimental data. The heat flux is estimated using modelled fire intensity and geometry and a corresponding view factor from an assumed solid flame. Key results The probability of normal and extreme fires reaching the WUI is of the order of 10−4 and 10−6 events/year, respectively. Total wildfire risk is of the order of 10−5 to 10−4 events/year Conclusions This methodology offers a comprehensive interpretation of wildfire risk that considers both wildfire likelihood and consequences. Implications The methodology is an interesting tool for quantitatively assessing wildfire risk of critical infrastructure and risk mitigation measures.

“…SFPE Handbook, Appendix 4 (2016). See also Lautenberger (2016) or other heat transfer text for a more comprehensive treatment of the topic. Another consequence of exposed timber surfaces leading to external flaming of longer duration and larger dimensions (compared to the ejected plumes from inert compartments) is the potential impact on building-to-fire spread, due to larger radiant heat fluxes in the far-field, in comparison with those from inert compartments.…”

This book provides guidance on the design of timber buildings for fire safety, developed within the global network Fire Safe Use of Wood (FSUW) and with reference to Eurocode 5 and other international codes. It introduces the behaviour of fires in timber buildings and describes strategies for providing safety if unwanted fires occur. It provides guidance on building design to prevent any fires from spreading while maintaining the load-bearing capacity of structural timber elements, connections and compartmentation. Also included is information on the reaction-to-fire of wood products according to different classification systems, as well as active measures of fire protection, and quality of workmanship and inspection as means of fulfilling fire safety objectives.

“…These objectives might be ignited by the accumulated heat to cause consequential damage or domino phenomena. Thus, from a risk assessment point of view, accurately predicting flame height is helpful in investigating the combustion states and safety distances [140].…”
