Risk Assessment Model:
|Risk assessment is a formal process of identifying
the likelihood and impact of hazards leading to loss, such as a train collision.
In the Risk Matrix metrics are assigned to the possible frequency and losses
of events using qualitative (eg catastrophic, critical, fatality, severe
injury) or quantitative (eg cost of repair/replacement of equipment or compensation)
methods. The matrix helps to improve safety performance efficiently by informing
decisions on safety priorities and assessing the impact of possible risk
controls. In order to populate the matrix, the causes and consequences of
each hazard may be modelled using fault and event tree analysis or other
mathematical models. Using a top down approach, the overall system (project,
product or plant) safety level must be assigned to its constituent sub-systems
and components. A quantitative risk assessment approach will result in assigning
numeral targets to sub-systems. A qualitative approach, on the other hand,
may be based on assigning high or medium integrity levels to sub-systems
and contributing factors.
|Dynamic Safety Risk Matrix
|The Safety Risk Matrix(SRM) of ISCaDE™ Pro
have many new and enhanced features as compared to its previous releases.
The risk classes within the Hazard Log can be configured based on specific project needs. The Safety Risk Classification Matrix would be automatically generated for a user defined configuration.
The standard features and functionalities as offered in previous versions are available, that include,
The most important among the new features added is the dynamic behaviour of SRM. The SRM can be modified and configured for any particular standard or industry. The labels of Risk Classes, Probabilities and Severities as well as their colours can be easily configured and customised using the XML Configuration Data Repository of ISCaDE™ Pro. That's why it covers a vast range of safety related industries.
As discussed earlier, different ISCaDE™ Pro projects can have different configurations and hence different risk matrices can be produced. Examples for defence and rail are shown below. Click the Safety Risk Matrix below for a larger view.
Clicking a particular cell of Safety Risk Classification Matrix not only filters the Accidents lying under that particular criterion but also filters the Hazards and Controls associated with the Filtered Accidents. That is, only those Hazards and Controls are displayed that are linked with the current filtered set of Accidents.
