risk assessment

listen to the pronunciation of risk assessment
İngilizce - İngilizce
The determination of the potential impact of an individual risk by measuring or otherwise assessing both the likelihood that it will occur and the impact if it should occur, and then combining the result according to an agreed rule to give a single measure of potential impact
The overall process of identifying all the risks to and from an activity and assessing the potential impact of each risk
the estimation of the likelihood of loss or damage and the magnitude of the consequence should the loss or damage occur In forestry, risk assessment includes the process of identifying the degree of risk that timber harvesting and road building imposes on adjacent and downslope social, economic, and forest resource values The severity of each potential hazard and the magnitude of the potential consequences that correspond to each hazard provide the overall risk associated with harvesting a site
An evaluation of a risk item which determines (1) what can go wrong, (2) how likely is it to occur, and (3) what are the consequences Assessment methods include: Risk Assessment, Probabilistic (PRA) - The process of determining the probability of occurrence of various risk scenarios \ Risk Assessment, Qualitative - A process which assigns qualitative risk measures like "high, medium, and low" to both the probability and the adverse consequences of items on a Significant Risk List These measures are often displayed in matrix format and could be relative to past projects or could be probability ranges These subjective assessments cannot be used for aggregating risks, and cannot be used for making quantitative tradeoffs Risk Assessment (Risk Analysis), Quantitative - The process of assigning proportional quantities to both the likelihood and the adverse consequences of risk items
The qualitative and quantitative evaluation performed in an effort to define the risk posed to human health and/or the environment by the presence or potential presence and/or use of specified pollutants
A systematic process that determines the likelihood of adverse health effects to a population after exposure to a hazard Health consequences may depend on the type of hazard and damage to infrastructure, loss of economic value, loss of function, loss of natural resources, loss of ecological systems, and environmental impacts and deterioration of health, mortality, and morbidity The major components of a risk assessment include a hazard identification/analysis and a vulnerability analysis that answer the following questions: What are the hazards that could affect a community? What can happen as a result of those hazards? How likely is each of the possible outcomes? When the possible outcomes occur, what are the likely consequences and losses? Risk assessment is a fundamental planning tool for disaster management, especially during prevention and mitigation activities See also hazard identification/analysis; vulnerability analysis
methods used to quantify risks to human health and the environment
the process of calculating the toxic effects of an exposure to a chemical substance and determining the potential uses of the substance
The standardized process of using interviews, observations, and other information to develop an accurate, reliable understanding of whether or not a victim is safe and unlikely to be harmed by the alleged offender in the near future Risk assessment does not definitively predict human behavior but weighs the probability that the victim will be harmed again
A study or evaluation that identifies and in many cases quantifies the potential harm posed to health and the environment by contamination on a property
Process of gathering data and making assessments to estimate short and long-term harmful affects on human health or the environment from exposure to hazards associated with a particular product or activity
Risk assessment is the identification and quantification of the risk resulting from a specific use or occurrence of a chemical, taking into account the possible harmful effects on individual people or society of using the chemical in the amount and manner proposed and all the possible routes of exposure Quantification ideally requires the establishment of dose-effect and dose-response relationships in likely target individuals and populations Compare "risk evaluation" below
The scientific process of evaluating the toxic properties of a chemical and the conditions of human exposure to it, in order to both ascertain the likelihood that exposed humans will be adversely affected, and to characterize the nature of the effects they may experience It may contain some or all of the following four steps: : a Hazard Identification--The determination of whether a particular chemical is or is not causally linked to particular health effect(s) : b Dose-Response Assessment--The determination of the relation between the magnitude of exposure and the probability of occurrence of the health effects in question : c Exposure Assessment--The determination of the extent of human exposure d Risk Characterization--The description of the nature and often the magnitude of human risk, including attendant uncertainty
The qualitative and quantitative evaluation performed in an effort to define the risk posed to human health and /or the environment by the presence or potential presence and/or use of specific pollutants
Qualitative and quantitative evaluation of the risk posed to human health and/or the environment by the actual or potential presence and/or use of specific pollutants
The process of establishing information regarding acceptable levels of a risk and/or levels of risk for an individual, group, society, or the environment
Produced from the combination of Threat and Vulnerability Assessments Characterized by analyzing the probability of destruction or incapacitation resulting from a threat's exploitation of a critical infrastructure's vulnerabilities
an evaluation to determine the risk posed to human health and the environment as a result of exposure to contaminants
The computation of risk Risk is a threat that exploits some vulnerability that could cause harm to an asset The risk algorithm computes the risk as a function of the assets, threats, and vulnerabilities One instance of a risk within a system is represented by the formula (Asset * Threat * Vulnerability) Total risk for a network equates to the sum of all the risk instances
The scientific evaluation of known or potential adverse health effects resulting from human exposure to foodborne hazards The process consists of the following steps: (1) hazard identification, (2) hazard characterization, (3)exposure assessment, and (4) risk characterization The definition includes quantitative risk assessment, which emphasizes reliance on numerical expressions of risk, and also qualitative expressions of risk, as well as an indication of the attendant uncertainties
The outcome of risk identification and risk estimation (identification and quantification of the risk resulting from a specific use or occurrence of a chemical compound including the establishment of dose-response relationships and target populations) When quantitative data on dose-response relationships for different types of population, including sensitive groups, are unavailable, such considerations may have to be expressed in more qualitative terms
1) Qualitative and quantitative evaluation of the risk posed to human health and/or the environment by the actual or potential presence and/or use of specific pollutants 2) The process used to determine the threats posed by hazardous substances Elements include: identification of the hazardous substances present in the environmental media; assessment of exposure and exposure pathways; assessment of the toxicity of the site's hazardous substances; characterization of human health risks; and characterization of the impacts and/or risks to the environment
A study of vulnerabilities, threats, likelihood, loss or impact, and theoretical effectiveness of security measures The process of evaluating threats and vulnerabilities, known and postulated, to determine expected loss and establish the degree of acceptability to system operations
A study to determine risks posed by the site if no cleanup action was taken and what cleanup levels need to be established to be protective of human health and the environment There are two types of risk assessments Human health risk assessment looks at the risks to humans from contamination at the site and an ecological risk assessment looks at the risks to ecosystems, such as plants, fish, and animals, from contamination at the site
