Changes in climate, land use, and management impact the occurrence severity of wildland fires many parts world. This is particularly evident Europe, where ongoing changes use have strongly modified fire patterns over last decades. Although satellite data by European Forest Fire Information System provide large-scale statistics across countries, there still a crucial need to collect summarize in-depth local analysis understanding condition associated challenges Europe. article aims general...
ABSTRACT Wildland–urban interface (WUI) fires are an increasing global challenge, and local knowledge is essential for efficient mitigation. In Norway, as the rest of Northern Europe, wildfires expected to increase in frequency severity, which will also WUI vulnerabilities. This study analyzes all registered vegetation damaging buildings Norway from January 2016 April 2023 (74 102 structures), with a case‐by‐case review 18 impacting two or more structures. We have identified that spring...
Fires in waste facilities represent significant potential social, economic and environmental challenges. Although the awareness of fires their consequences has increased recent years, fire safety challenges remain. Norway Sweden have been studied to make an overall assessment propose measures for safety. Common ignition causes include self-heating, thermal runaway batteries, friction, human activity, technical or electrical error unfavourable combined storage. High-risk wastes general,...
Two fire experiments have been conducted to study sprinkler system extinguishing performance in a compartment (13 m2) with an adjacent corridor (12 m2), both exposed cross-laminated timber (CLT). Four nozzles were installed the and two compartment. In Experiment 1, was fully functional successfully controlled concealed fire. 2, disconnected, while operative, giving flashover after 5 min large flames emerging into corridor, rapidly worsening evacuation conditions. Despite four activated...
Dry wood pellets (diameter 8 mm) of mixed Norwegian spruce and pine were tested in samples 1.25 kg (1.7 l) configurations with without air draft from below. The placed a vertical 15 cm diameter cylinder on top hot plate. Air inlet, when allowed, came through narrow openings the bottom periphery. bulk void 36% formed channels for gas flows within bed. Initially, heated externally below 6 h. Time series distributed temperatures recorded, together values mass. Smouldering was observed two...
Abstract The impact of Photovoltaic (PV) installations on the fire safety buildings must be considered in all building projects where such energy systems are established. holistic largely depends how PV installation is by different actors during design and construction process. Research has therefore been undertaken to study performance-based regulations combination with lack national guidelines affect overall considerations for Norway. Four factors were found govern which extent emphasised...
Biomass fuels in large storage units are prone to self-heating and ignition causing smoldering fires. Here, the susceptibility of such processes parameters is explored through small-scale experiments. In a silo geometry, wood pellets samples size 0.75 1.5 kg were heated from below initiate smoldering, while top was open, allowing convective exchange gases between porous sample surroundings. The thermally insulated sidewalls reduce heat flow lateral direction similar way that additional...
Synchronized, pulsating temperatures are observed experimentally in smoldering fires. The entire sample volume (1.8 l) participates the pulsations (pulse period 2–4 h). synchrony lasts up to 25 h and is followed by a spontaneous transition either disordered combustion or self-extinguishment. synchronization obtained when fuel bed cooled brink of extinguishment. Calculations for adiabatic conditions, including heat generation from (nonlinear temperature) storage (linear temperature), predict...
Summary Fires in wood waste storages cause financial losses, are difficult to extinguish, and emit large amounts of fire effluents. The mechanisms related fires chip piles not well elucidated. To find suitable preventive measures for handling such waste, a better understanding the physical properties is needed. present study investigates how granularity affects smoldering transition flaming piles. Eighteen experiments with samples inside top‐ventilated, vertical cylinder were conducted....
Abstract The Scandinavian countries have in later years seen several severe wildfires and is expected to exhibit more fire danger. While direct flame spread has been an important topic wildfire research, there a need for development ensure that experimental methods are relevant characteristics. To lab conditions fire-resilient material work, large lab-scale (2×4 meters) experiments were conducted on various fuels. Its behaviour (such as rate of spread, fireline intensity length) was compared...
Abstract The present research explores the influence of Bjørnis Fire Bear on residential fire safety in Norway. Our survey, comprising 1275 participants, reveals that spurred adoption 5181 measures among respondents, averaging 4.1 per household. data suggests a positive association between exposure to and an increased number implemented. These results highlight Bjørnis’ efficiency fostering awareness about safety, potentially serving as model for introducing or sustaining similar mascots...
Abstract Understanding of wildfire risk requires an understanding the natural species’ fire dynamics. This study investigates characteristics common wildland species in Norwegian forests – stair-step moss, lingonberry shrub, juniper, bilberry, and heather. Cone calorimetry experiments were conducted after conditioning samples to similar moisture content. Stair-step moss bilberry stems exhibited longer burning times lower peak heat release rates, suggesting a slower, more sustained...
Abstract Photovoltaic modules have been shown to influence how a fire propagates across flat roof, but the circumstances for which building attached photovoltaic (BAPV) promote propagation on sloped roof is not studied in detail. Therefore, series of small-medium- and large-scale experiments with B ROOF (t2)-rated bituminous membrane wood chipboard substrate has performed. Steel plates mimicking non-combustible (PV) were placed at different distances above roof. Different sized cribs gap...
Since the 1990s, Norwegian management for cultural heritage has increased its focus on finding effective solutions protecting Norway's wooden from fire damage. The medieval churches in general, including stave churches, with their interiors and inventories, are of special interest. However, usefulness valuable inventories when fighting been questioned. An experiment was carried out to find manageable large by using covers case fire. seven commercially available products conducted fighters...
