Guidance on design and construction of the built environment against wildland urban interface fire hazard: a review

Guidance on design and construction of the built environment against wildland urban interface fire hazard: a review

Steven Gwynne, Movement Strategies, London, UK Noureddine Be´nichou, National Research Council, Ottawa, Canada Received: 28 December 2018/Accepted: 28 August 2019 Abstract. Wildland-Urban Interface (WUI) fires, a worldwide problem, are gaining more importance over time due to climate change and increased urbanization in WUI areas. Some jurisdictions have provided standards, codes and guidelines, which may greatly help planning, prevention and protection against wildfires. This work presents a wide systematic review of standards, codes and guidelines for the design and con- struction of the built environment against WUI fire hazard from North American, European, Oceanic countries, alongside with trans-national codes. The main informa- tion reviewed includes: the definition of WUI hazards, risk areas and related severity classes, the influence of land and environmental factors, the requirements for building materials, constructions, utilities, fire protection measures and road access. Some common threads among the documents reviewed have been highlighted. They include similar attempts at: (a) defining WUI risk areas and severity classes, (b) considering land factors including the defensible space (also known as ignition zones), (c) pre- scribing requirements for buildings and access. The main gaps highlighted in the existing standards/guidelines include lacks of detailed and widespread requirements for resources, fire protection measures, and lacks of taking into account environmen- tal factors in detail. The main design and construction principles contained in the reviewed documents are largely based on previous research and/or good practices. Hence, the main contributions of this paper consist in: (a) systematically disseminate these guidance concepts, (b) setting a potential basis for the development of stan- dards/guidelines in other jurisdictions lacking dedicated WUI fire design guidance, (c) highlighting gaps in existing standards/guidelines to be addressed by current and future research.

Experimental and numerical thermo-mechanical analysis of the influence of thermoplastic slabs installation on the assessment of their fire hazard

Experimental and numerical thermo-mechanical analysis of the influence of thermoplastic slabs installation on the assessment of their fire hazard

1. Introduction Thermoplastic polymers are widely used in industry and everyday life, e.g., in furniture, interior decoration. Being combustible materials, they contribute to the fire hazard. The vertical configuration of plastic items is recognized to emphasize hazard by increasing the burning rate [ 1 , 2 ]. Most studies about the burning of vertically oriented slabs have concerned PMMA (poly (methylmethacrylate)) because it exhibits a non-charring (complete) combustion, which can be considered as a well-known and simple decomposition mechanism. A lot of attention was paid to flame spread and the influence of sample geometry (thickness, width, leading edge) was studied in downward [ 3 , 4 ] or upward [ 5–7 ] configuration. Correlations were established between flame spread rate [ 8 , 9 ] or flame height and heat flux [ 8 , 9 ]. More re- cently, Pizzo et al. [ 10 ] studied the combustion of thick clear PMMA slab in vertical position. Most of these studies were performed with relatively thick samples of PMMA. However, the thickness of sample has an influence on the burning kinetics. Paul [ 11 ] performed studies with vertical PMMA sample on cone calorimeter and showed the effect of thickness on the heat release rate. As the sample thickness is

How design fires can be used in fire hazard analysis

How design fires can be used in fire hazard analysis

EXAMPLE OF A 3-STOREY APARTMENT BUILDING Based on the methodology described in previous sections, the smoke movement and occupant evacuation as a result of a fire that has occurred in a particular location in a building can be calculated. As an example, the results of a recent study 12 using FiRECAM is described here on the trade-off of mandatory sprinkler protection verses a faster fire department response. In this study, a 3-storey apartment building was used as a model building, assumed to be as shown in Fig. 2. The building is 40 m wide and 21.5 m deep. Each level has 8 apartment units, a central corridor and two stairshafts at the two ends of the corridor. Each apartment unit is assumed to have an area of 100 m 2 . A fire could start in any one of the units and spread through the

How design fires can be used in fire hazard analysis

How design fires can be used in fire hazard analysis

The size of the fuel element governs the size and intensity of the design fire. A large fuel element that is representative of the total amount of combustibles in a typical apartment unit or office room will easily create a flashover fire. On the other hand, a small fuel element, representing the burning of a small object without spreading to all the combustibles in a room, will create a non-flashover fire because the heat generated is not sufficient to create a flashover fire. As for smouldering fires, a low intensity heat source, such as cigarettes, and special fabrics can be used to create non- flaming smouldering fires. The fire growth model that is employed in the NRC FiRECAM follows this approach 7 .

Securitization and Optimal Retention under Moral Hazard

Securitization and Optimal Retention under Moral Hazard

5 We are looking for the optimal retention in the case of securitization that will keep the originator’s incentive at the most favorable level. First we assume that there is no securitization and calculate the originator’s first best effort . Then we assume that there is securitization, while effort is observable and there is no moral hazard. In this case, given the first best effort level, we determine the optimal amount of retention. Finally we investigate the optimal amount of retention with moral hazard. We must consider three kinds of constraints in this model:

Adverse selection and moral hazard in health insurance

Adverse selection and moral hazard in health insurance

Using lemma 4 the equilibrium separting is due to the fact that the single crossing is veri…ed. Lemma 5 implies that full insurance can not be o¤ered to the high health risk type and low health risk type obtains full coverage. Only the low health risk type obtains the moral hazard contract whereas the high health risk type are restricted to partial insurance. This result seems to be in opposition to the Rothschild and Stiglitz’s analysis. They focus only on the …nancial risk. In our model, the high health risk type become the low …nancial risk type because the insurable health loss lead them to make most preventive e¤ort.

Caldera rim collapse: A hidden volcanic hazard

Caldera rim collapse: A hidden volcanic hazard

Monitoring volcanoes to measure ground deformation with, for instance, geodetic data or highly sophisticated techniques like interferometry radar (SAR), are likely to forecast the timing of eventual collapses. However, it is sometimes hard to make a decision about which part of a volcano should be monitored as potential hazards may be dif ficult to assess. To this respect, caldera rim collapse reveals that classic and careful field studies remain an invaluable toll to identify hazard, especially in the case of buried calderas. Where buried calderas are suspected, field studies should provide a map where principal hazard and risk are clearly identi fied around the hidden ring fault, which in turn allows ef ficient monitoring and successful forecasting.
