This chapter considers the natural hazard Risk Manager as an agent for choosing between interventions that affect the impact of future hazards. As such, it is possible to proceed broadly quantitatively, and to set aside the many less-quantifiable concerns that arise during a period of real-time hazard management. Thus the aim is to describe a framework in which it is possible to address questio...

exposure to welding gases can cause health adverse effects. risk assessment is a useful tool for good assessment of exposed workers. the purpose of this study was to determine the risk levels for exposed welders to welding gases. welders (n=239) were selected from iranian natural gas transmission pipelines industry from four regions in iran including assaluyeh, omidieh, loshan, and borujen. ozo...

the purpose of this study was to conduct a quantitative risk assessment for pah exposure forconsumers at a night market in taiwan. the major methods assessed potential risk under different exposure scenarios based on bap equivalent concentration (bapeq) and incremental lifetime cancer risk (ilcr) models. we performed experimental sampling at a night market from 27 october through 22 november 20...

Recently, a novel approach towards semi-quantitative IT security risk assessment has been proposed in the draft IEC 62443-3-2. This approach is analyzed from several different angles, e.g. embedding into the overall standard series, semantic and methodological aspects. As a result, several systematic flaws in the approach are exposed. As a way forward, an alternative approach is proposed which ...

This paper presents a quantitative risk assessment method based on the portrayal of risks using scenario trees, the translation of evidence into probability curves and the aggregation of scenarios using Latin Hypercube simulation. An example of a quantitative risk assessment on the importation of swine for slaughter illustrates the interpretation of evidence of two swine disease risks: pseudora...

Risk assessment has been widely used as a tool for the development of waste management facilities. At the strategic level, risk assessment is used to inform decision makers about the planning process. In terms of a specific site, environmental risk assessment is used to identify risk management options. As an engineering tool, risk assessment is used to optimize the mitigation measures required...

Background: Chemical contaminants present in the work environments include gases, vapors, and solid and liquid suspended particles. The number of factories producing chemicals has increased significantly. Each year, new products are introduced into the market. Consequently, the number of employees at risk of exposure to these materials is increased. Hazardous chemicals are used in the petrochem...
