Download or read book Relationships for Smoke Control Calculations written by and published by . This book was released on 1995 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: These Technical Memoranda have been prepared in order to provide engineering relationships which can be used as part of the overall fire safety design of buildings with atria an other spaces where large numbers of people may be exposed to smoke, toxic atmospheres and hot gases. The need for smoke control depends on many aspects of the building design and use, including the combustibility of the contents, mobility of occupants, and ease of escape. The smoke control measures needed, if any, may be simple perhaps exploiting the normal ventilation system-or they may require extra equipment and controls. These considerations are taken in context in fire safety engineering design and are dealt with elsewhere(l). This publication is intended as a source document for design guidance. The relationships are based on published, authoritative information, where this is available, and the limits of applicability are suggested. In cases where the basis of a relationship is not firmly established, the relationship is given on the understanding that it may be superseded when further information is available. This is made clear in the text. It should normally be possible to use the information given here without resort to computational fluid dynamics (CFD) or physical modelling, although these are valuable tools which can be used for unusual designs or to generate future design guidance. The basic principles involved in CFD and what is offered to the designer are described in Appendix 2. Background notes and sources for these Memoranda are given in Appendix 3. However, information on smoke generation and smoke control is increasing rapidly and new data can be used to augment the guidance given here.
Download or read book Fluid Mechanics Aspects of Fire and Smoke Dynamics in Enclosures written by Bart Merci and published by CRC Press. This book was released on 2016-03-30 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book aims at fulfilling the need for a handbook at undergraduate and starting researcher level on fire and smoke dynamics in enclosures, giving fluid mechanics aspects a central role. Fluid mechanics are essential at the level of combustion, heat transfer and fire suppression, but they are described only cursorily in most of the existing fire safety science literature, including handbooks. The scope of this handbook ranges from the discussion of the basic equations for turbulent flows with combustion, through a discussion on the structure of flames, to fire and smoke plumes and their interaction with enclosure boundaries. Using this knowledge, the fire dynamics and smoke and heat control in enclosures are discussed. Subsequently, a chapter is devoted to the effect of water and the related fluid mechanics aspects. The book concludes with a chapter on CFD (Computational Fluid Dynamics), the increasingly popular calculation method in the field of fire safety science.

Download or read book Principles of Element Design written by Peter Rich and published by Routledge. This book was released on 2012-10-02 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: The construction of buildings is learnt through experience and the inheritance of a tradition in forming buildings over several thousand years. Successful construction learns from this experience which becomes embodied in principles of application. Though materials and techniques change, various elements have to perform the same function. 'Principles of Element Design' identifies all the relevant elements and then breaks these elements down into all their basic constituents, making it possible for students to fully understand the given theory and principles behind each part. As all building projects are subject to guidance through the Building Regulations and British Standards, this book gives an immediate reference back to relevant information to help practitioners and contractors identify key documents needed.

Download or read book Quantitative Risk Assessment in Fire Safety written by Ganapathy Ramachandran and published by Routledge. This book was released on 2011-02-25 with total page 385 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fire safety regulations in many countries require Fire Risk Assessment to be carried out for buildings such as workplaces and houses in multiple occupation. This duty is imposed on a "Responsible Person" and also on any other persons having control of buildings in compliance with the requirements specified in the regulations. Although regulations only require a qualitative assessment of fire risk, a quantitative assessment is an essential first step for performing cost-benefit analysis of alternative fire strategies to comply with the regulations and selecting the most cost-effective strategy. To facilitate this assessment, various qualitative, semi-quantitative and quantitative techniques of fire risk assessment, already developed, are critically reviewed in this book and some improvements are suggested. This book is intended to be an expanded version of Part 7: Probabilistic risk assessment, 2003, a Published Document (PD) to British Standard BS 7974: 2001 on the Application of Fire Safety Engineering Principles to the Design of Buildings. Ganapathy Ramachandran and David Charters were co-authors of PD 7974 Part 7. Quantitative Risk Assessment in Fire Safety is essential reading for consultants, academics, fire safety engineers, fire officers, building control officers and students in fire safety engineering. It also provides useful tools for fire protection economists and risk management professionals, including those involved in fire insurance underwriting.

Download or read book Handbook of Smoke Control Engineering written by John H. Klote and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Handbook of Smoke Control Engineering extends the tradition of the comprehensive treatment of smoke control technology, including fundamental concepts, smoke control systems, and methods of analysis. The handbook provides information needed for the analysis of design fires, including considerations of sprinklers, shielded fires, and transient fuels. It is also extremely useful for practicing engineers, architects, code officials, researchers, and students. Following the success of Principles of Smoke Management in 2002, this new book incorporates the latest research and advances in smoke control practice. New topics in the handbook are: controls, fire and smoke control in transport tunnels, and full-scale fire testing. For those getting started with the computer models CONTAM and CFAST, there are simplified instructions with examples. This is the first smoke control book with climatic data so that users will have easy-to-use weather data specifically for smoke control design for locations in the U.S., Canada, and throughout the world. Systems discussed in the handbook include those for stairwell pressurization, elevator pressurization, zoned smoke control, and atrium smoke control. The latest smoke control research and most current engineering approaches are also included. Unique to previous smoke control literature, this handbook provides many example calculations to help designers prevent smoke damage.
Download or read book Air Distribution in Rooms written by H.B. Awbi and published by Elsevier. This book was released on 2000 with total page 746 pages. Available in PDF, EPUB and Kindle. Book excerpt: The air distribution in occupied spaces is a major issue of public concern. It is widely recognized that the quality of air and the nature of airflow can affect the health of occupants and the energy consumed in buildings and transport vehicles. ROOMVENT is the principal international conference in the field of air distribution. It was first initiated in 1987 by SCANVAC, the Scandinavian Federation of Heating, Ventilating and Sanitary Engineering Associations in Denmark, Finland, Iceland, Norway and Sweden. The aim of the Conference is to bring together researchers from universities and research institutes, engineers from industry and government officials and policy makers, with the goal of experiencing the latest techniques for measuring and analyzing indoor air flow, the visualization of indoor air flow patterns, the evaluation of ventilation parameters and the most recent developments in computer simulation techniques of room airflow. It is hoped that the theme of ROOMVENT 2000 "Ventilation for Health and Sustainable Environment" will set the scene for room air distribution research and development for the new millennium.

This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.
Download or read book Sprinklers and Smoke Management in Enclosures written by Dalia E.E. Khalil and published by CRC Press. This book was released on 2020-05-14 with total page 179 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses smoke management in enclosures and provides a platform for understanding the principles of smoke propagation and spread, heat release rate, and the effect of sprinklers on suppression. Considering how sprinkler systems have become a vital part of firefighting systems in enclosures, the book evaluates the effect of sprinkler activation on the behavior of fire-induced smoke and the interaction of water particles with the smoke layer. It studies two base case models where the sprinklers’ effect on the fire curve was considered. This base case was assessed with two smoke extraction systems, namely, a ducted system and an impulse ventilation system. By focusing on key elements, such as visibility, ceiling height, and fire curve, the results of the study will be of interest to mechanical engineers, HVAC professionals, and fire safety professionals and investigators. Features Includes case models and scenarios to evaluate real examples from different applications Studies the effect of sprinkler activation on the behavior of fire-induced smoke Explores various factors, such as ceiling height, sprinkler operating pressure, and fire curve Discusses the interaction of water particles with the smoke layer Utilizes Pyrosim software for CFD modeling

Download or read book Secondhand Smoke Exposure and Cardiovascular Effects written by Institute of Medicine and published by National Academies Press. This book was released on 2010-02-21 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: Data suggest that exposure to secondhand smoke can result in heart disease in nonsmoking adults. Recently, progress has been made in reducing involuntary exposure to secondhand smoke through legislation banning smoking in workplaces, restaurants, and other public places. The effect of legislation to ban smoking and its effects on the cardiovascular health of nonsmoking adults, however, remains a question. Secondhand Smoke Exposure and Cardiovascular Effects reviews available scientific literature to assess the relationship between secondhand smoke exposure and acute coronary events. The authors, experts in secondhand smoke exposure and toxicology, clinical cardiology, epidemiology, and statistics, find that there is about a 25 to 30 percent increase in the risk of coronary heart disease from exposure to secondhand smoke. Their findings agree with the 2006 Surgeon General's Report conclusion that there are increased risks of coronary heart disease morbidity and mortality among men and women exposed to secondhand smoke. However, the authors note that the evidence for determining the magnitude of the relationship between chronic secondhand smoke exposure and coronary heart disease is not very strong. Public health professionals will rely upon Secondhand Smoke Exposure and Cardiovascular Effects for its survey of critical epidemiological studies on the effects of smoking bans and evidence of links between secondhand smoke exposure and cardiovascular events, as well as its findings and recommendations.
