Available in PDF, EPUB and Kindle. Book excerpt: The Ocean Breeze-Dry Gulch (OB/DG) atmospheric dispersion model is used extensively by the USAF Air Weather Service for predicting the hazard zone resulting from an accidental toxic chemical spill. This model is an empirical and statistical model derived from the Ocean Breeze, Dry Gulch, and Prairie Grass experiments conducted in the late 50's and early 60's. the USAF Scientific Advisory Board recently recommended that the OB/DG model be replaced with a current state-of-the-art dispersion model. This report represents the first step toward evaluating the OB/DG model and finding a suitable replacement. The hazard distances computed from the OB/DG model for different meteorological conditions are compared with the hazard distances calculated with the Shell Oil co. SPILLS model and a modified version of the model. In the modified Shell model, the discrete Pasquill stability categories are replaced with a continuous stability parameter, and surface roughness is included as a factor in defining the rate of cloud growth. The OB/DG model agrees quite favorably with the modified Shell model except at low wind speeds where it predicts considerably lower distances. The Shell model calculates generally larger distances and much greater fluctuations with wind speed, and therefore does not agree as well with the OB/DG model. The similarity in output between the modified Shell model and the OB/DG model lends support to further consideration of this model as a possible replacement to the OB/DG model.

Download or read book Validation of a Surface layer Windflow Model Using Climatology and Meteorological Tower Data from Vandenberg AFB California written by John M. Lanicci and published by . This book was released on 1986 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the 2nd phase of a study involving a surface-layer windflow model. The model produces a two-dimensional (x-y plane) variational analysis of windflow by employing Gauss' principle of least constraints to adjust an initial windfield to effects of topography, stability, momentum advection, and mass conservation. It used detailed terrain data (100 to 200 m horizontal resolution) to compensate for sparse meteorological data available over the small areas for which the model is run (25 to 250 sq km). The first phase involved testing of the model to effects of stability and vegetation using terrain, vegetation, and climate for Ft. Polk, LA. The 2nd phase involves further model development, including changes in meteorological data input as well as changes in wind and stability initializations. Model experiments using artificially-produced terrain were conducted to test these changes. A two-part model validation was then performed using climate data and archived meteorological tower data from Vandenberg AFB, California. The area of interest is 11 x 12 km, and covers the South Vandenberg Launch Complex.

This book was released on 2013-06-29 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over recent years there has been an increasing awareness of the risks of locating hazardous industries near heavily populated, environmentally sensitive areas. This new awareness demands a novel approach to safety planning for hazardous industries; one that looks at the problem from the point of view of integrated regional risk assessment which, besides the risks arising from natural events, should also include the risks arising from the processing plants, storage and the transportation of dangerous goods. Volume I of Integrated Regional Risk Assessment highlights the main procedures for the assessment of risks to health and environmental impacts from continuous emissions of pollutants into air, water and soil under normal operating conditions. Volume II deals with the assessment of consequences of accidental releases, helping to answer such questions as: What can go wrong? What are the effects and consequences? How often will it happen? £/LIST£ The main procedural steps are supported by relevant, internationally recognised methods of risk assessment. The book also reviews criteria and guidelines for the implementation of risk assessment and management at different stages. Audience: Students, engineers, and scientists in charge of developing new methodologies for hazard analysis and risk assessment; practitioners of environmental protection; local and governmental authorities charged with implementing environmental risk impact procedures and guidelines.

This book was released on 1997-05-30 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 1950s and 1960s, the U.S. Army conducted atmospheric dispersion tests in many American cities using fluorescent particles of zinc cadmium sulfide (ZnCdS) to develop and verify meteorological models to estimate the dispersal of aerosols. Upon learning of the tests, many citizens and some public health officials in the affected cities raised concerns about the health consequences of the tests. This book assesses the public health effects of the Army's tests, including the toxicity of ZnCdS, the toxicity of surrogate cadmium compounds, the environmental fate of ZnCdS, the extent of public exposures from the dispersion tests, and the risks of such exposures.

Download or read book Lees Loss Prevention in the Process Industries written by Frank Lees and published by Elsevier. This book was released on 2005-01-25 with total page 3708 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the last three decades the process industries have grown very rapidly, with corresponding increases in the quantities of hazardous materials in process, storage or transport. Plants have become larger and are often situated in or close to densely populated areas. Increased hazard of loss of life or property is continually highlighted with incidents such as Flixborough, Bhopal, Chernobyl, Three Mile Island, the Phillips 66 incident, and Piper Alpha to name but a few. The field of Loss Prevention is, and continues to, be of supreme importance to countless companies, municipalities and governments around the world, because of the trend for processing plants to become larger and often be situated in or close to densely populated areas, thus increasing the hazard of loss of life or property. This book is a detailed guidebook to defending against these, and many other, hazards. It could without exaggeration be referred to as the "bible" for the process industries. This is THE standard reference work for chemical and process engineering safety professionals. For years, it has been the most complete collection of information on the theory, practice, design elements, equipment, regulations and laws covering the field of process safety. An entire library of alternative books (and cross-referencing systems) would be needed to replace or improve upon it, but everything of importance to safety professionals, engineers and managers can be found in this all-encompassing reference instead. Frank Lees' world renowned work has been fully revised and expanded by a team of leading chemical and process engineers working under the guidance of one of the world’s chief experts in this field. Sam Mannan is professor of chemical engineering at Texas A&M University, and heads the Mary Kay O’Connor Process Safety Center at Texas A&M. He received his MS and Ph.D. in chemical engineering from the University of Oklahoma, and joined the chemical engineering department at Texas A&M University as a professor in 1997. He has over 20 years of experience as an engineer, working both in industry and academia. New detail is added to chapters on fire safety, engineering, explosion hazards, analysis and suppression, and new appendices feature more recent disasters. The many thousands of references have been updated along with standards and codes of practice issued by authorities in the US, UK/Europe and internationally. In addition to all this, more regulatory relevance and case studies have been included in this edition. Written in a clear and concise style, Loss Prevention in the Process Industries covers traditional areas of personal safety as well as the more technological aspects and thus provides balanced and in-depth coverage of the whole field of safety and loss prevention. * A must-have standard reference for chemical and process engineering safety professionals * The most complete collection of information on the theory, practice, design elements, equipment and laws that pertain to process safety * Only single work to provide everything; principles, practice, codes, standards, data and references needed by those practicing in the field
