in the case of hazardous materials management, selected routes for carrying hazardous materials (i.e.,hazmat) have significant effects on locating hazmat distribution centers. since, risk and cost are usuallyconsidered as two main attributes to determine the best routes, optimized locations are sequentially outlineddepending on selected routes. in the present paper, two different approaches of ...

Hazardous materials are harmful to environment and human health due to their toxic ingredients. It is very important to intensify efforts in the safety management of hazardous materials, and fundamentally prevent and reduce accidents. In this study, we consider a time-dependent hazardous materials vehicle routing problem in a two-echelon supply chain system. The goal is to determine the departu...

Rail transportation plays a critical role to safely and efficiently transport hazardous materials. A number of strategies have been implemented or are being developed to reduce the risk of hazardous materials release from train accidents. Each of these risk reduction strategies has its safety benefit and corresponding implementation cost. However, the cost effectiveness of the integration of di...

New methods for the reduction and remediation of hazardous wastes like carcinogenic organic solvents, toxic materials, and nuclear contamination are vital to environmental health. Procedures for effective waste reduction, detection, and removal are important components of any such methods. Toward this end, polymeric smart materials are finding useful applications. Polymer-bound smart catalysts ...

On September 16, 2013, the North Carolina Division of Public Health was notified of an elemental (metallic and liquid) mercury spill on a school bus. An elementary student boarded the bus with approximately 1 pound (454 g) of elemental mercury contained in a film canister, which the student had taken from an adult relative who had found it in a neighbor's shed. The canister was handled by sever...

bake-out was executed against the newly constructed apartment buildings using two methods to find out the effect of improvement on the indoor air quality and identify the concentration changes in the indoor air by the bake-out method for 3 months after occupancy. from two methods of bake-out executed before occupying, we did not find any reduction effect on the hazardous substances in the indoo...

Air pollution studies for hazardous gases in Taiwan generally consider the impact on the human body, and always put the emphasis on large immobile and mobile pollution sources (like chimneys and vehicles), but they have ignore the leakage between pipelines in process industries. When hazardous materials leak imperceptibly, they increase the pathogenic risk to the workers at the workplace. Since...

Railroads play a key role in the transportation of hazardous materials in North America. Rail transport differs from highway transport in several aspects, an important one being that rail transport involves trains in which many railcars carrying hazardous materials travel together. By contrast to truck accidents, it is possible that a train accident may involve multiple hazardous materials cars...
