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...

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 ...

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...

fractionation studies on the sediment samples provide valuable information on the nature of the metals bound to the sediments. thirty three sediment samples of river adyar were collected during two seasons and speciation study was carried out. the industrial and domestic effluents are directed into the river course at many points in the middle and lower of the adyar river. to ascertain the exte...

conclusions overall, the results derived from these studies indicated that hospital safety levels in most of the surveyed hospitals were moderate. although the situation in hospitals is not critical, there is a need to plan and take appropriate measures to improve the safety level of the hospitals. results hospital preparedness in disaster was evaluated in three dimensions: structural, non-stru...

the safety of hydrogen generation facilities is the main concern in their process operation. this study was conducted to identify the hazards and evaluate the risks of a hydrogen generation plant. for this purpose, prha (process hazard analysis) was applied for hazard identification while lopa (layer of protection analysis) was used for risk assessment. the study was conducted in the hydrogen p...

Cyber risks are an important point on the business agenda in every company, but they are difficult to assess due to the absence of reliable data and profound analyses. To improve this situation, we identify cyber losses from an operational risk database and analyze these with methods from the field of actuarial science. Specifically, we apply operational risk models in order to yield consistent...

Quantitative Risk Assessment (QRA) models have already been developed and used to assess various risks of road tunnels, including the societal risk and expected number of fatalities (ENF). Fire in a road tunnel is considered as the most severe disaster in that road tunnel is an enclosed space. The risk assessment for fire in road tunnels involves a number of parameters. Some of these parameters...
