Definition
|
|
It is a process that consists of a number of sequential steps as follows :
|
-
 Hazard Identification: Identifying sources of process accidents involving release of hazardous material in the atmosphere , and the various ways ( i.e. scenarios ) they could occur.
- Consequence Assessment: Estimating the probable zone of impact of accidents as well as the scale and / or probability of damages with respect to human beings and plant equipment and other structures.
- Accident Frequency Assessment : Computation of the average likelihood of accidents.
- Risk Estimation: Combining accident consequence and frequency to obtain risk distribution with in and beyond a process plant.

Stages of Risk Analysis
|
Any plant during its design and construction stages can undergo any of the following hazard identification and hazard analysis techniques :
- Process Design Check lists
- HAZOP studies
- Failure Mode and Effects Analysis
- What If analysis
- Fault Tree analysis
- Event Tree Analysis
|
CMSRSL will identify hazards associated with the operations and select worst case scenarios for estimation of consequences. Reputed software models will be used for consequence estimation. Based on the estimated frequency of occurrence, risk reduction measures will be suggested to the management for effective implementation.
