Classification of risk assessment
- 1. Classification of Risk Assessment
- 2. Risk AssessmentAssessment is a systematic procedure for describing and quantifying the risk associated with hazardous substance, process, action or event. It involves:Identification of hazardQuantification of hazardQuantification of probability of occurrence of hazardEstimation of risk
- 3. Classification of Risk AssessmentAccording to scope of work, risk assessment may be classified as: Environmental Risk Assessment
- 4. Industrial Risk Assessment
- 5. Reliability Risk Assessment
- 6. Financial Risk Assessment
- 7. Health Risk AssessmentEnvironmental Risk AssessmentRiskSourceExposure ProcessConsequ--ence processRelease Assessment (Hazard Identification)
- 9. Consequence Assessment (Toxicity Assessment)
- 10. Risk Estimation (Risk Characterization)Environmental Risk AssessmentHazard identificationIdentification of all possible sources of hazards such chemicals, events, etc.
- 11. Estimate their strength at various mediums
- 12. Rank them according to their severity
- 13. Set up priority for the most vulnerable onesParameters used for screening and rankingConcentration
- 15. Mobility
- 16. Persistence in the environment
- 17. Treat ability Environmental Risk Assessment Exposure Assessment
- 18. Activities involve in exposure assessment (Benzene)Release mechanism (volatilization)Transport mechanism (air convection)Transfer mechanism (volatilization)Transformation mechanism (chemical reaction)Exposure point (air)Receptors (population)Exposure Rout (inhalation)
