Figure 1. Risk Assessment Matrix (RAM). The RAC quantifies the risk level associated with the hazard’s probability and severity ratings. Risk can fall into one of four levels. Each of the four levels requires specific actions to mitigate. The RAC helps to prioritize hazards such that those that pose the greatest risk can be addressed first.
Assess and score the risk (i.e. probability X severity) using the Risk Matrix as per TPL Risk Assessment Matrix (RAM) (refer to Section 6.3). List out present controls (preventive and recovery).
Preliminary hazard analysis (PHA) is a semi-quantitative analysis that is performed to: Identify all potential hazards and hazardous events that may lead to an accident. Rank the identified hazardous events according to their severity. Identify required hazard controls and follow-up actions.
1 Φεβ 2018 · PHA encompasses several techniques to evaluate and control hazards and risk levels respective to process operations to assess the suitability and effectiveness of existing safety barriers, and to help determine whether additional barriers or risk mitigation
RISK ASSESSMENT MATRIX. A risk matrix is just used for ranking events and decide whether you need to accept the risk or reduce it through mitigations. Decisions need to be based on an underlying analysis (such as a bowtie diagram), that will tell what will cause the unsafe event and what an organization is already doing to control it. 5A. 5B
Annex 1: Risk identification for SHF as per risk categorization (strategic, governance, financial, internal, coordination or hazard) 2 Risk Level analysis is based on a combination of risk likelihood/probability criteria and risk rating by consequence and likelihood.
