This book contributes to more reliable and realistic predictions by focusing on sampling times from a few seconds to a few hours. Its objectives include developing clear definitions of statistical terms, such as plume sampling time, concentration averaging time, receptor exposure time, and other terms often confused with each other or incorrectly specified in hazard assessments; identifying and quantifying situations for which there is no adequate knowledge to predict concentration fluctuations in the near-field, close to sources, and far downwind where dispersion is dominated by atmospheric turbulence; identifying areas where further information is required to define concentration variability statistics; and formulating an operation model for concentration fluctuations based on the current state of knowledge of dispersion processes.

The second edition of this essential reference updates and combines two earlier titles to capture the many technological advances for predicting the "footprint" of a vapor cloud release. Cited by EPA in its 1996 document, "Off-Site Consequence Analysis Guidance," the aim of the book is to encourage and facilitate the development and use of dispersion modeling as an everyday tool, providing practical understanding of basic physical and chemical principles, guidance in selecting release scenarios and the best available models, and information and examples on how to run some models and interpret outputs. Equally useful to beginners and experts, it compares 22 programs based on input from model developers, and presents 7 examples of typical accidental release scenarios. The book comes with a disk providing input and output data for scenarios.

The ITM conference series has always had a strong spirit of cooperation under the NATO/CCMS umbrella, and with the considerable interest fram Partner countries to participate in the ITM conferences, it provides an excellent opportunity to create ties between scientists. Whereas all previous ITM conferences have taken place in NATO countries, the 23rd ITM takes place in a Cooperative Partner country, Bulgaria, and is hosted by the National Institute of Meteorology and Hydrology, Bulgarian Academy of Sciences. This fact reflects a general wish for a closer connection and collaboration among scientists fram Partner and NATO countries. This volume contains the papers from the 23rd NATO/CCMS International Technical Meetings on Air Pollution Modelling and Its Application, being held September 28 - October 2, 1998, at Riviera Holiday Club, Varna, Bulgaria. It was attended by 120 participants from 30 countries. Thanks are due to all who made it possible to plan, carry through, and follow up the meeting, and to the participants who made the conference so successful. Special thanks are due to the sponsoring institutions: ATO/CCMS EURASAP RIS0 BAS 3M NATO/CCMS - Committee on the Challenges of Modem Society EURASAP - European Association for the Science of Air Pollution RIS0 - Ris0 National Laboratory, Denmark NIMH - National Institute of Meteorology and Hydralogy, Bulgaria BAS - Bulgarian Academy of Sciences 3M Representation office, Bulgaria Prestige Business Ltd. , Bulgaria The excellent collaboration with CIM (Company for International Meetings Ltd.

Chemical process quantitative risk analysis (CPQRA) as applied to the CPI was first fully described in the first edition of this CCPS Guidelines book. This second edition is packed with information reflecting advances in this evolving methodology, and includes worked examples on a CD-ROM. CPQRA is used to identify incident scenarios and evaluate their risk by defining the probability of failure, the various consequences and the potential impact of those consequences. It is an invaluable methodology to evaluate these when qualitative analysis cannot provide adequate understanding and when more information is needed for risk management. This technique provides a means to evaluate acute hazards and alternative risk reduction strategies, and identify areas for cost-effective risk reduction. There are no simple answers when complex issues are concerned, but CPQRA2 offers a cogent, well-illustrated guide to applying these risk-analysis techniques, particularly to risk control studies. Special Details: Includes CD-ROM with example problems worked using Excel and Quattro Pro. For use with Windows 95, 98, and NT.

Prevention, preparedness, response and recovery--the key components of emergency planning--form the major sections of this work. The book first describes PSM (Process Safety Management) as the key to prevention, then goes on to consider the main features of a preparedness program, including recognizing credible incidents, planning practical strategy to deal with these incidents, selecting necessary physical support systems and equipment, and developing a complete emergency response plan. The Response section presents the functions implemented during an actual emergency and concludes with a section on managing cleanup and restoration of operations. The many tables and figures include Sample Incident Command System Plans for both large and small organizations, OSHA and EPA regulations affecting planning, sample Fire Emergency Action Levels, HAZMAT Responder Levels, and OSHA Emergency Training Requirements.

Dedicated to the Memory and Spirit of Donald F. Othmer Though there are many industry practices for building design and siting, they do not always apply to all sectors of the industry, or ensure consistent levels of safety. This practical book, written by the same author as API Recommended Practice 752, provides the details to implement the recommended practice, "Management of Hazards Associated with Location of Process Plant Buildings." Its contents include safety guidelines on fire and explosion risks to process plant buildings as a result of events external to the building, which can apply across the spectrum of industries, and to conditions at any site. The book also offers guidance on assessing, screening, and managing risks associated with building design and siting. Two appendices give extensive coverage of explosion and fire phenomena, and effects and principles of blast-resistant design.
