This book was released on 2011 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: Full-scale experiments are conducted to study the effects of different water-based indirect and combination initial attack methods on the compartment environment and firefighter during compartment fire suppression, with an aim toward improving manual fire suppression effectiveness and firefighter safety. Hot layer temperatures typical of room fire conditions are developed in the test compartment using wood cribs. Five suppression methods including straight stream, penciling, continuous wide and narrow fog, and a wide angle burst method are examined for two different spray angles and nozzle pressures. Temperatures, heat flux, gas velocity, and gas concentrations are monitored for the duration of each experiment in the fire compartment, along with temperatures and gas concentrations in the area of the firefighter, just outside the compartment. Realistic fire conditions are repeatedly established in the test compartment, with each fuel load allowing up to nine suppression applications per fire. The repeatability of the compartment temperatures are demonstrated by the consistent hot layer temperature stratification in the room, along with the uniformity of the hot layer throughout a test, and the consistency of the temperature from test to test. The repeatability of each suppression method is also demonstrated by comparing results of compartment cooling achieved in repeat tests. Differences in average compartment temperature before and during suppression indicate that penciling tactics provide little cooling of the compartment. In narrow fog attacks, the hot layer is pushed toward the floor, resulting in increased temperatures in the lower layer, generally an undesired result. Wide angle fog methods may have greater impact on compartment temperature as compared to straight stream or narrow fog methods, however, they also result in large increases in temperature at the firefighter. Wide angle burst tactics less effectively cool the compartment gases than continuous methods, but also lead to less impact on the firefighter. Greater numbers of bursts increase cooling of the compartment, but at the expense of increased impact on the firefighter. Including impact on the firefighter, continuous straight stream methods, at a nozzle discharge pressure of 700 kPa and aimed to the top of the rear compartment wall, appear the best choice for initial attack on the fire developed in these experiments. Due to variability between real fire scenarios and experiments such as these, significantly more study of the various suppression tactics is required before the most effective methods of suppression can be determined for a given set of fire scenarios.

Download or read book The Evolving Fireground written by Sean Gray and published by Fire Engineering Books. This book was released on 2018-07-02 with total page 154 pages. Available in PDF, EPUB and Kindle. Book excerpt: Everything we do--or don't do--affects the fire. Deputy Chief P.J. Norwood and Captain Sean Gray discuss how fireground strategy and tactics have evolved in light of fire research conducted around the world. They discuss the fire tetrahedron and how fuel, heat, and air all affect a fire’s growth or extinguishment. Gray and Norwood take the lessons learned from the research as well as their general knowledge of the fireground to illustrate safer and more effective ways to operate on the fireground. They discuss how to apply this new understanding of fire behavior to two of the fire service’s most important tasks: search and fire attack. This book is an important resource for anyone wanting to put new fire dynamics research to action. You will learn: --How firefighting activities affect the fire tetrahedron --To stay safe while working in the flow path on the fireground --Search methods that isolate the firefighter and victim --Fire attack methods that minimize the air fed to the fire --Incident command size up and decision making

Download or read book Initial Attack Fire Suppression Spatial Resource Allocation and Fire Prevention Policy in California the United States and the Republic of Korea written by Yohan Lee and published by . This book was released on 2012 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this dissertation, I combined a scenario-based, standard-response optimization model with a stochastic simulation model to improve the efficiency of the deployment of initial attack firefighting resources on wildland fires in California and the Republic of Korea. The optimization model minimizes the expected number of fires that do not receive a standard response--defined as the number of resources by type that must arrive at the fire within a specified time limit--subject to budget and station capacity constraints and uncertainty about the daily number and location of fires. The simulation model produces a set of fire scenarios in which a combination of fire count, fire locations, fire ignition times, and fire behavior occur. Compared with the current deployment, the deployment obtained with optimization shifts resources from the planning unit with the highest fire load to the planning unit with the highest standard response requirements. Resource deployments that result from relaxing constraints on station capacity achieve greater containment success by encouraging consolidation of resources into stations with high dispatch frequency, thus increasing the probability of resource availability on high fire count days. I extended the standard response framework to examine how a policy priority influences the optimal spatial allocation and performance of initial attack resources. I found that the policy goal of a fire manager changes the optimal spatial allocation of initial attack firefighting resources on a heterogeneous landscape, especially, for the socio-economic value of a potential fire location. Furthermore, I investigated the tradeoff between the number of firefighting resources and the level of fire ignition prevention efforts mitigating the probability of human-made fires in the Republic of Korea where most fires are caused by human activities. I found that fire ignition prevention is as cost-effective as initial attack resources given the current budget in the Republic of Korea on reducing the expected number of fires not receiving the standard response. From the comparison of the California and Republic of Korea cases, I can identify "rules of thumb" to be followed when allocating IA resources in particular ecological and policy settings.

Download or read book Positive Pressure Attack for Ventilation Firefighting written by Kriss Garcia and published by PennWell Books. This book was released on 2006 with total page 334 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past decades, lightweight building construction methods and the use of manmade materials in construction and furnishings have become more and more common. The time until structural failure can be expected in a fire has been reduced, and firefighters have seen hotter fires that generate high levels of deadly gasses. But the ventilation methods used by modern firefighters have not kept pace. Positive pressure was first used in the fire service to ventilate a structure after the fire was knocked down. Authors Kriss Garcia and Reinhard Kauffmann have taken positive pressure a step further to achieve effective ventilation in coordination with aggressive fire attack, called positive pressure attack (PPA). Properly used PPA allows firefighters great control over the interior environment of a fire building, and starts at the earliest stages of the operation when ventilation can provide the greatest benefit for victims, firefighters, and the structure. With a small investment in equipment and a commitment to training, any fire department can implement PPA at the company level. Subjects covered in this book include: - Basics of positive pressure and how to maximize its effectiveness for fireground ventilation. - PPA: how effective ventilation can be coordinated to support an aggressive fire attack. - Safety considerations and limitations of PPA and positive pressure. - Other ways positive pressure blowers can be used to help victims and firefighters in a variety of situations. - Implementing PPA on a department, and how to train each engine company to become its own firefighting force that can accomplish both ventilation and fire attack.

Book excerpt: "In September 2004, the Canadian Council of Forest Ministers established a federal, provincial, and territorial task group of assistant deputy ministers (ADMs) and commissioned the development of the Canadian Wildland Fire Strategy (CWFS). The ADMs created an intergovernmental team of analysts, experienced fire managers, and researchers, known as the CWFS Core Team, to consult with Canadian and international experts, collate information, conduct analyses, and present the findings. This team was directed to assess the current state of wildland fire management in Canada, examine the key influences and trends, and identify possible desired future states and how they could be achieved. This publication comprises a collection of nine reports written by the CWFS Core Team members and their associates. Collectively these papers include syntheses, analyses, and perspective articles that address a variety of the social, economic, and biophysical aspects of wildland fire and its management as well as policy, science, and operational issues in Canada."--Pub. desc.
