Download or read book Evaluation of a Movable Concrete Barrier System written by Benjamin H. Cottrell and published by . This book was released on 1994 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: The movable concrete barrier (MCB) system consists of 1-m-long sections of barrier connected by steel pins in hinges to form a barrier wall that is moved laterally with a transport/transfer vehicle. The MCB system allows for the quick closing and opening of a lane for construction work. A 1-km section of barrier can be laterally positioned in about 10 minutes. This system aids in the safe maintenance and reconstruction of highways with minimum inconvenience to the motoring public by limiting lane closures to the non-peak periods. The Virginia Department of Transportation and its contractors used the MCB system on two road-widening projects on I-66 in Fairfax County. The objectives of this research were to evaluate the effectiveness of the MCB system and to develop guidelines for its use. The costs associated with the use of the system along with problems and benefits were examined. The results of the study showed that the MCB system performed adequately in its transfer operations, in redirecting errant vehicles, and in protecting the construction workers. Some general guidelines were developed for using the MCB system. The MCB system should be used on high volume, congested freeways (1) where there is a need for barrier protection and quick opening and closing of lanes or (2) where there is a need for a median barrier that can be quickly shifted.

Download or read book Assessment of the Performance of Engineered Waste Containment Barriers written by National Research Council and published by National Academies Press. This book was released on 2007-09-22 with total page 135 pages. Available in PDF, EPUB and Kindle. Book excerpt: President Carter's 1980 declaration of a state of emergency at Love Canal, New York, recognized that residents' health had been affected by nearby chemical waste sites. The Resource Conservation and Recovery Act, enacted in 1976, ushered in a new era of waste management disposal designed to protect the public from harm. It required that modern waste containment systems use "engineered" barriers designed to isolate hazardous and toxic wastes and prevent them from seeping into the environment. These containment systems are now employed at thousands of waste sites around the United States, and their effectiveness must be continually monitored. Assessment of the Performance of Engineered Waste Containment Barriers assesses the performance of waste containment barriers to date. Existing data suggest that waste containment systems with liners and covers, when constructed and maintained in accordance with current regulations, are performing well thus far. However, they have not been in existence long enough to assess long-term (postclosure) performance, which may extend for hundreds of years. The book makes recommendations on how to improve future assessments and increase confidence in predictions of barrier system performance which will be of interest to policy makers, environmental interest groups, industrial waste producers, and industrial waste management industry.

Download or read book Vulnerability Assessment of Physical Protection Systems written by Mary Lynn Garcia and published by Elsevier. This book was released on 2005-12-08 with total page 399 pages. Available in PDF, EPUB and Kindle. Book excerpt: Vulnerability Assessment of Physical Protection Systems guides the reader through the topic of physical security with a unique, detailed and scientific approach. The book describes the entire vulnerability assessment (VA) process, from the start of planning through final analysis and out brief to senior management. It draws heavily on the principles introduced in the author's best-selling Design and Evaluation of Physical Protection Systems and allows readers to apply those principles and conduct a VA that is aligned with system objectives and achievable with existing budget and personnel resources. The text covers the full spectrum of a VA, including negotiating tasks with the customer; project management and planning of the VA; team membership; and step-by-step details for performing the VA, data collection and analysis. It also provides important notes on how to use the VA to suggest design improvements and generate multiple design options. The text ends with a discussion of how to out brief the results to senior management in order to gain their support and demonstrate the return on investment of their security dollar. Several new tools are introduced to help readers organize and use the information at their sites and allow them to mix the physical protection system with other risk management measures to reduce risk to an acceptable level at an affordable cost and with the least operational impact. This book will be of interest to physical security professionals, security managers, security students and professionals, and government officials. - Guides the reader through the topic of physical security doing so with a unique, detailed and scientific approach - Takes the reader from beginning to end and step-by-step through a Vulnerability Assessment - Over 150 figures and tables to illustrate key concepts
