Available in PDF, EPUB and Kindle. Book excerpt: A representative range of mattresses was subjected to cigarette and burning paper ignition sources. Ignition by cigarettes was achieved only at the taped edge of the mattresses which had this design feature. Al I mattresses were readily ignited by the paper source but they showed differing f lame propagation, and heat and smoke release rates. Of particular note was the rapid release of large amounts of heat and smoke by the rubber/polyurethane foam and one of the polyurethane mattresses A prototype institutional mattress which incorporated an interliner showed a significant improvement in fire performance in terms of ignitability, flame propagation, and heat and smoke release. It is concluded that it is feasible to use 'mini-mattresses' for the assessment of such mattresses.

Available in PDF, EPUB and Kindle. Book excerpt: This study addresses the fire behavior of bed assemblies, including a mattress, foundation and bedclothes. The focus is on development and application of a reproducible means of simulating the thermal impact which burning bedclothes materials impose on a mattress. Twelve dtfferent sets of bedclothes were burned on top of an inert mattress to obtain data on heat release rate, flame spread rates and, to a lesser degree, heat flux to nearby objects. Six of these sets were selected for characterization of the heat flux patterns they impose on an inert mattress surface. A unique, infrared imaging technique was developed for this purpose. The results, in terms of peak heat flux, duration and area, were used to develop a pair of propane burners which impose on the side and top of a mattress heat flux patterns which mimic those imposed at a typical, fixed location by burning bedclothes. These burners were applied to a set of five mattress designs, including one typical of current residential mattresses; the four other designs included potentially less flammable design elements to permit a wide range of fire behaviors. This facilitated a broad assessment of the ability of the gas burners to predict the fire behavior of mattresses. The duration of the burner application was varied. Also, as a check on the burner-induced behavior, the same mattress designs were tested with one bedclothes combination. All of the altered designs offered some modification in fire behavior but they differed strongly in overall effect. The effects ranged from a delay in the time to reach an undiminished heat release rate peak to greatly reduced mattress involvement in the fire. The burners successfully predicted the behavior of four of the mattress designs. They failed to predict the fire behavior (with burning bedclothes) of one design since the bedclothes produced a phenomenon (internal overpressurization and seam rupture) which the burners did not produce.

Available in PDF, EPUB and Kindle. Book excerpt: A representative range of pillows has been examined to assess their fire behaviour when subjected to small smouldering and flaming ignition sources. The sources were placed both on top of and below pillows in combination with pillow cases, sheets and a simulated mattress. Only one pillow (feather filled) was not ignited under any of the conditions used and the other pillows showed a range of ignition and burning behaviours. The report discusses the data obtained and concludes that pillows deserve special attention in assessment of the fire performance of bedding assemblies.

Download or read book Fire Behaviour of Beds and Bedding Materials written by W. D. Woolley and published by . This book was released on 1975 with total page 33 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire tests with measurements of temperatures, radiation levels and smoke production have been carried out using domestic beds fitted with full bedding materials in a full-scale compartment-corridor. The tests have included mattresses made of polyurethane of various types, hair, spring interior and foamed rubber with mattress covers of cotton, flame retarded cotton or proofed nylon. Some tests with hair or glass fibre cloth protective interlinings are also recorded. The study has shown that a rapid development of fire in bed and bedding materials can take place with certain combinations of mattresses and their covers. The type of cover is extremely important in the overall fire development particularly with polyurethane mattresses. A substantial improvement in the fire behaviour of many of the principal types of beds tested can be achieved by a careful selection of bedding materials, such as the type of mattress cover, and in certain cases by the use of protective interlingings.

Download or read book Wildland Fire Behaviour written by Mark A. Finney and published by CSIRO PUBLISHING. This book was released on 2021-11-01 with total page 675 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wildland fires have an irreplaceable role in sustaining many of our forests, shrublands and grasslands. They can be used as controlled burns or occur as free-burning wildfires, and can sometimes be dangerous and destructive to fauna, human communities and natural resources. Through scientific understanding of their behaviour, we can develop the tools to reliably use and manage fires across landscapes in ways that are compatible with the constraints of modern society while benefiting the ecosystems. The science of wildland fire is incomplete, however. Even the simplest fire behaviours – how fast they spread, how long they burn and how large they get – arise from a dynamical system of physical processes interacting in unexplored ways with heterogeneous biological, ecological and meteorological factors across many scales of time and space. The physics of heat transfer, combustion and ignition, for example, operate in all fires at millimetre and millisecond scales but wildfires can become conflagrations that burn for months and exceed millions of hectares. Wildland Fire Behaviour: Dynamics, Principles and Processes examines what is known and unknown about wildfire behaviours. The authors introduce fire as a dynamical system along with traditional steady-state concepts. They then break down the system into its primary physical components, describe how they depend upon environmental factors, and explore system dynamics by constructing and exercising a nonlinear model. The limits of modelling and knowledge are discussed throughout but emphasised by review of large fire behaviours. Advancing knowledge of fire behaviours will require a multidisciplinary approach and rely on quality measurements from experimental research, as covered in the final chapters.

Download or read book Grassfires written by Phil Cheney and published by CSIRO PUBLISHING. This book was released on 2008 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Grassfirespresents the latest information from CSIRO on the behavior and spread of fires in grasslands. This second edition follows ten years of research aimed at improving the understanding of fundamental processes involved in the behavior of bushfires and grassfires. The book has been extensively revised and new case studies have been added to reflect the latest findings in research and investigations. The book covers all aspects of fire behavior and spread in the major types of grasses in Australia. It examines the factors that affect fire behavior in continuous grassy fuels; fire in spinifex fuels; the effect of weather and topography on fire spread; wildfire suppression strategies; and how to reconstruct grassfire spread after the fact. The three fire-spread meters designed by CSIRO and used for the prediction of fire danger and rate of spread of grassfires are explained and their use and limitations discussed. This new edition expands on the historical view of grassfires with respect to extensive Aboriginal burning, combustion chemistry, flame structure and temperature, spotting and spread in discontinuous/eaten out fuels, and the effect of wind in complex terrain. The case studies in the chapter "Wildfires and Their Suppression" have been updated and include the major wild grassfire events of recent years, the January 2003 ACT fires and the 2005 Wangary, SA fire. The "Myths, Facts and Fallacies" chapter includes new myths and a new section on personal safety during a wild grass fire. Of interest to all rural fire fighters and rural landholders, students and teachers of courses on landscape and ecological processes, rural and peri-urban dwellers, fire authorities and researchers.
Download or read book Assessment of Factors Affecting Fire Performance of Mattresses written by Nist and published by CreateSpace. This book was released on 2014-03-07 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: An in-depth analysis of U.S. residential fire statistics shows that although the total number of fires and deaths due to mattress fires has dropped as a result of several regulatory approaches, the number of deaths per 1000 mattress/bedding fires has increased over past 3 decades. To address the increasing number of deaths due to mattress fires, the open flame mattress flammability regulation (16 CFR 1633) was recently introduced in the U.S. The 16 CFR 1633 prescribes performance standards rather than design standards; this allows manufacturers the flexibility to meet the needs of the consumer without sacrificing fire safety. This flammability regulation for residential mattress has generated much interest in understanding the burning behavior of mattresses as well as in developing new materials for mattress construction. To comply with this regulation, it is essential to understand mattress construction, fire performance testing, factors affecting mattress flammability, and compliance solutions. This report reviews the impact of current mattress flammability standards, examines factors affecting mattress flammability, and reviews full-scale and bench-scale test methods that are being developed for mattresses. The soft materials used in the mattress set, including cushioning materials, fire blocking materials, and tickings, act both individually and collectively to affect the fire performance. The performance of fire barrier materials designed to protect the inner cushioning material from heat and flame is largely dependent on the choice of cushioning material and ticking. When used with an incompatible combination of filling material and ticking, a fire barrier may fail to protect thermal degradation and subsequent burning of filling material. Some of the challenges in designing mattresses have been identified and reported here.
Download or read book Fire Phenomena and the Earth System written by Claire M. Belcher and published by John Wiley & Sons. This book was released on 2013-04-08 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire plays a key role in Earth system processes. Wildfires influence the carbon cycle and the nutrient balance of our planet, and may even play a role in regulating the oxygen content of our atmosphere. The evolutionary history of plants has been intimately tied to fire and this in part explains the distribution of our ecosystems and their ability to withstand the effects of natural fires today. Fire Phenomena and the Earth System brings together the various subdisciplines within fire science to provide a synthesis of our understanding of the role of wildfire in the Earth system. The book shows how knowledge of fire phenomena and the nature of combustion of natural fuels can be used to understand modern wildfires, interpret fire events in the geological record and to understand the role of fire in a variety of Earth system processes. By bringing together chapters written by leading international researchers from a range of geological, environmental, chemical and engineering disciplines, the book will stimulate the exchange of ideas and knowledge across these subject areas. Fire Phenomena and the Earth System provides a truly interdisciplinary guide that can inform us about Earth’s past, present and beyond. Readership: Advanced students and researchers across a wide range of earth, environmental and life sciences, including biogeochemistry, paleoclimatology, atmospheric science, palaeontology and paleoecology, combustion science, ecology and forestry.
Download or read book Investigation of Methods Used to Predict the Heat Release Rate and Enclosure Temperatures During Mattress Fires written by and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Fires in buildings ranging in size from small residential houses to large office buildings and sports stadiums pose significant threats to human safety. Many advances have been made in the area of fire behaviour modeling and have lead to much safer, and more efficient fire protection engineering designs, saving countless lives. Fire, however, is still a difficult phenomenon to accurately model and the most important quantity used to describe a fire is the heat (energy) release rate (HRR). Predictions of the fire hazard posed by mattresses, using relatively simple modeling techniques, were investigated in this research work and compared to full-scale experimental results. Specifically, several common methods of predicting the HRR from a mattress fire were examined. Current spatial separation guidelines, which exist in order to mitigate fire spread between buildings, were used to predict radiation heat flux levels emitted by a burning building and compared to experimental results measured in the field. Enclosure ceiling temperatures, predicted using the Alpert temperature correlation, and average hot gas layer temperature predictions were also compared to experimental results. Results from this work indicate that the t-squared fire heat release rate modeling technique combined with the common Alpert ceiling temperature correlation, provide a reasonable prediction of real-life fire temperatures as results within 30% were obtained. The cone calorimeter was also found to be a useful tool in the prediction of full-scale fire behaviour and the guidelines used for spatial separation calculations were found to predict the radiant heat flux emitted by a burning building reasonably well.

Download or read book Large Outdoor Fire Dynamics written by Keisuke Himoto and published by CRC Press. This book was released on 2022-12-22 with total page 415 pages. Available in PDF, EPUB and Kindle. Book excerpt: Large Outdoor Fire Dynamics provides the essential knowledge for the hazard evaluation of large outdoor fires, including wildland, WUI (wildland-urban interface), and urban fires. The spread of outdoor fires can be viewed as a successive occurrence of physical and chemical processes – solid fuel combustion, heat transfer to surrounding combustibles, and ignition of heated combustibles – which are explained herein. Engineering equations frequently used in practical hazard analyses are derived and then integrated to implement a computational code predicting fire spread among discretely distributed combustibles. This code facilitates learning the procedure of hazard evaluation for large outdoor fires. Chapters cover underlying assumptions for analyzing fire spread behavior in large outdoor fires, namely, wind conditions near the ground surface and fundamentals of heat transfer; the physical mechanism of fire spread in and between combustibles, specifically focusing on fire plumes (both reacting and non-reacting) and firebrand dispersal; and the spatial modeling of 3D objects and developing the computational framework for predicting fire spread. The book is ideal for engineers, researchers, and graduate students in fire safety as well as mechanical engineering, civil engineering, disaster management, safety engineering, and planning. Companion source codes are available online.
