Computer processing and image analysis technologies have improved substantially over the course of the past decade. This rapidly advancing technology along with the emphasis on video surveillance since 911 has propelled the development of effective video image detection (VID) systems for ?re. Fire protection system designers initially employed these VID systems for use in large facilities, outdoor locations and tunnels. However, video-based detection is being used for a broadening range of applications [e. g. , 1]. For example, these systems are c- rently installed in electrical power plants, paper mills, document storage facilities, historic municipal buildings, nuclear research facilities, automotive plants, wa- house/distribution centers, and onshore and offshore oil platforms. The 2007 edition of NFPA 72, National Fire Alarm Code [2], recognized the use of VID systems for ?ame and smoke detection. Although recognized, there is limited prescriptive installation and use requirements and there is a general desire by many for the development of performance criteria that ultimately could be utilized for the design of systems or the creation of standards. Since the underlying VID technology and development of standard and network-based camera systems are in a period of fairly rapid advancement [3–5], it is not possible to de?ne a comprehensive set of stand-alone prescriptive requirements. The performance of VID systems depends on both the video hardware and the software algorithms; there is no basic underlying principle, such as there is for ionization or pho- electric detection for smoke detectors. Consequently, performance-based inst- lation and operation requirements are needed.

Researchers working in a related field will also find the book valuable.

Natural fires can be considered as scale-dependant, non-linear processes of mass, momentum and heat transport, resulting from a turbulent reactive and radiative fluid medium flowing over a complex medium, the vegetal fuel. In natural outdoor conditions, the experimental study of natural fires at real scale needs the development of an original metrology, one able to capture the large range of time and length scales involved in its dynamic nature and also able to resist the thermal, mechanical and chemical aggression of flames on devices. Robust, accurate and poorly intrusive tools must be carefully set-up and used for gaining very fluctuating data over long periods. These signals also need the development of original post-processing tools that take into account the non-steady nature of their stochastic components. Metrology for Fire Experiments in Outdoor Conditions closely analyzes these features, and also describes measurements techniques, the thermal insulation of fragile electronic systems, data acquisition, measurement errors and optimal post-processing algorithms. This book is intended for practitioners as a reference guide for optimizing measurements techniques in an outdoor environment. Advanced-level students and researchers will also find the book invaluable.

Fire Flow Water Consumption in Sprinklered and Unsprinklered Buildings offers a detailed analysis for calculating the fire water demand required in buildings with existing and non-existant sprinkler systems. The installation of automatic sprinkler systems can significantly reduce the amount of water needed during a fire, but it requires water for commissioning, inspection, testing, and maintenance (CITM). This book provides an estimate of fire water used under both fire conditions, including CITM, to allow communities to develop fire water fees for both sprinklered and unsprinklered buildings that are proportional to the anticipated fire water usage.The types of buildings analyzed include residential (family dwellings as well as those up to four stories in height), business, assembly, institutional, mercantile, and storage facilities. Water volume was studied using guidelines from the International Code Council, the National Fire Protection Association, and the Insurance Services Office. Fire Flow Water Consumption in Sprinklered and Unsprinklered Buildings is intended for practitioners as a tool for analyzing water consumption in fire situations and for providing them with key information on the best types of water systems in a variety of buildings. Researchers working in building planning and safety will also find the book valuable.

The book will also prove valuable for fire hazard researchers and those involved with fire department response, applicable detection systems, and fire growth suppression.

Environmental concerns and advances in architectural technologies have lead to a greater number of green buildings or buildings with green, eco-friendly elements. However, from a practical standpoint, there is no incident reporting system in the world that tracks data on fire incidents in green buildings. Fire safety objectives are not explicitly considered in most green rating schemes, and green design features have been associated with photovoltaic panels and roof materials, lightweight timber frame buildings, and combustible insulation materials. Fire Safety Challenges of Green Buildings is the result of an extensive global literature review that sought to identify issues related to green building elements or features and ways to ensure those issues are tracked for future improvement.The book identifies actual incidents of fires in green buildings or involving green building elements, points out issues with green building elements that would increase fire risk, clarifies reports and studies that address ways to reduce fire risk in green design elements, and compares research studies that explicitly incorporate fire safety into green building design. The authors also pinpoint gaps and specific research needs associated with understanding and addressing fire risk and hazards with green building design. Using their data, the authors developed a set of matrices relating these green attributes and potential fire hazards. With these comprehensive tools, potential mitigation strategies for addressing the relative increase in fire risk or hazard associated with the green building elements and features have been identified. Fire Safety Challenges of Green Buildings is intended for practitioners as a tool for analyzing building safety issues in green architecture and developing methods for tracking data related to green design elements and their potential hazards.

It offers clear recommendations for the future to help ensure efficiency and safety with fire protection equipment. Researchers working in a related field will also find the book valuable.

In this age of climatic and financial uncertainty, it becomes increasingly important to balance the cost, benefits and risk of wildfire management. In the United States, increased wildland fire activity over the last 15 years has resulted in drastic damage and loss of life. An associated rapid increase in fire management costs has consumed higher portions of budgets of public entities involved in wildfire management, challenging their ability to fulfill other responsibilities. Increased public scrutiny highlights the need to improve wildland fire management for cost effectiveness. This book closely examines the development of basic wildfire suppression cost models for the United States and their application to a wide range of settings from informing incident decision making to programmatic review. The book also explores emerging trends in suppression costs and introduces new spatially explicit cost models to account for characteristics of the burned landscape. Finally, it discusses how emerging risk assessment tools can be better informed by integrating management cost models with wildfire simulation models and values at risk. Economics of Wildfire Management is intended for practitioners as a reference guide. Advanced-level students and researchers will also find the book invaluable.

This SpringerBrief presents information on a wide variety of hazards and the damage potential caused by installation of a photovoltaic (PV) system. The current installation practices for PV systems on roofs create electrical, fire, structural, and weather-related hazards that do not comply to current codes, standards and guidance documents. Potential dangers include structural loading, wind loads, hail, snow, debris accumulation, seismic hazards, firefighting hazards, and electrical hazards. Despite the increased popularity of PV systems after the environmental movement, research shows that the costs of installing PV systems outweigh the benefits. Hazards of PV systems on roofs have caused several incidents in the United States; the most notable in Bakersfield, California, and Mount Holly, North Carolina. Designed for fire engineers and professionals, Best Practices for Commercial Roof-Mounted Photovoltaic System Installation offers recommendations to set up PV systems safely and sustainably.

This SpringerBrief offers careful assessments of the appropriateness and effectiveness of currently available methodologies for fire flow. It explains the water supply requirements for firefighting including rate of flow, the residual pressure required at that flow, and the duration that is necessary to control a major fire in a specific structure. First reviewing existing fire flow calculation methodologies in the U.S. and globally, the authors determine the new information necessary to validate the existing fire flow calculation methodologies. After identifying 19 methods from the U.S., UK, France, Germany, the Netherlands, New England, and Canada, two types of methods are evaluated: those for building planning based on fire and building code requirements, and those for on-scene fire service use. Building planning methods are also examined, including an explanation of the range of building variables that determine fire flow. A survey form for fire departments is provided to help fire departments identify key predictive features based on construction and building parameters. Researchers and professionals in fire engineering will find the recommendations in Evaluation of Fire Flow Methodologies valuable.

This brief develops a data collection plan to assess loss related to electrical surges in homes, and explores the potential impact devices that prevent these surges could have in mitigating these losses. Key topics such as surge sources, surge effects and residential surge protection are clearly defined. Recent fire safety codes proposed a requirement that every dwelling unit be fitted with a surge protection device, as every year there is property damage to electrical and electronic equipment resulting from electrical surges. These proposals have not been implemented due to a lack of reliable data, which this brief seeks to change. The authors evaluate surge phenomena and their sources, surge protection methods, surge protection strategies and industry standards in order to present a data plan that can accurately assess loss related to electrical surges in homes.

This SpringerBrief presents strategies for fire mitigation based on combustible assembly systems of exterior walls. Providing background information on common exterior wall systems, the mechanisms of fire spread, and case studies, it examines the difficulties in controlling a fire with several materials and assembly methods. The brief compiles information on typical fire scenarios which involve the exterior wall, along with further exploration into test methods, approval and regulatory requirements for the various assembly systems. Offering testing approaches for possible mitigation strategies, the brief takes into account that current commercial wall assembly systems are constructed to improve energy performance, reduce water and air infiltration, and allow for aesthetic design flexibility. Exterior Insulation Finish Systems, metal composite claddings, high-pressure laminates, and weather-resistive barrier systems all have components which directly impact the fire hazard. Recommendations for future exterior wall construction are based on identified knowledge gaps.

This book investigates the feasibility of developing a tool that enables fire departments to estimate the value of their services to a community in terms of environmental and financial impact. This book provides a summary of this effort, which resulted in development of a prototype tool for fire department use.The impact of fire on a community is usually measured in terms of the number of fires, human casualties, and property damage. There are, however, more subtle impacts of fire that are not so easily estimated but contribute to the measure of overall performance of the fire service in protecting a community. While environmental and economic impact assessment methodologies exist as separate systems, they generally require a high level of knowledge that is outside the scope of most fire departments. A relatively simple methodology for estimating the environmental and economic impact of fires helps communities understand the degree to which fire department activities can benefit a community’s environmental and economic well-being.The scope and approach for this prototype tool is explained, including risk assessment, cost benefit analysis, life cycle assessment, integration and implementation, and sensitivity and uncertainty analysis. It includes multiple case studies and offers statistical support for future expansion of the tool.Fire service professionals will find this a useful new approach to presenting value in a community, as well as a method for examining their own financial and environmental plans.

This book presents the results of an experiment assessing the impact of spruce wood joints on the creation and development of fire when these joints are applied within a façade. The book includes an extensive analysis of wooden cladding, which is a flammable material in which the elements are connected lengthwise using various types of joint. The parameters of the experiment, as well as the setting, material criteria and evaluation criteria are described in detail. The results confirm that the joint type used has an impact on the selected evaluation criteria and thus also on the potential spread of fire.

This book addresses the performance of a multi-storey timber building subjected to a model fire that represents a real, potentially devastating internal fire. Readers will learn about factors concerning fire hazards in buildings; the mechanisms of how fires start and spread; and the degrading impact of fire on wood and wood-based materials, especially their mechanical properties. The book also discusses the fire resistance of timber buildings and the design principles for fire safety, summarised in Eurocodes.In turn, a fire test on a full-size wooden structure demonstrates the principles discussed. The test makes up an essential part of the book, as to its individual steps: the development, planning, execution and subsequent assessment. This is complemented by detailed temperature monitoring at hundreds of individual spots and the reaction of the wood constructions, illustrated in extensive photo documentation.  The temperature and fire development presented there show the fire's initial mechanism and its further behaviour in a wood construction. The test proved the feasibility of fire protection and safe design of timber buildings, offering insights that can be generally applied in research, material and construction development. Accordingly, the book will be especially useful for architects, building and fire engineers, as well as researchers dealing with the fire performance of timber buildings.

This book offers a comprehensive approach to the assessment of fire hazards of electrical cables. The first part of the book describes division of cables, main parameters of electrical cables, and fault scenarios of cables leading to fire or occupant injuries. The traditional approach to fire hazards of electrical cables assessment is also described in the first part. The second part of the book is focused on the creation and description of a new approach to fire hazard assessment of electrical cables. The new approach is based on the assessment of both ignition parameters of electrical cables and the impact of their fires on the surrounding area. The ignition parameters include critical heat flux, ignition temperature, and critical electrical current. The impact of cable fires on the surrounding area is expressed by the released heat, toxicity of combustion products (determined by the amount of released carbon oxides and oxygen consumed), and visibility (determined by the smoke extinction area). Newly created approach is practically illustrated on specific types of cables (power cables classified to B2ca and Fca reaction to fire class) in this book. The book is intended mainly for academics in the fields of both fire protection engineering and electrical engineering. Besides that, the professionals in fire safety will find valuable information concerning impact of electrical cables on the safety of occupants and structures during fire in the book. In addition, the book sheds light on the issue of fire safety of electrical cables for the professionals in both electrical and power engineering. Last but not least, the book is appropriate also for students in the fields of fire, electrical, and power engineering in bachelor, master, and Ph.D. degree.
