Safety risk analysis - 3SE
Reviewedhttps://www.3se.info/3se-onto/terms/safety-risk-analysis-3se-069c1ab34ba5783e
Risk analysis which is relevant for safety engineering.
It includes the following steps:
(1) Identify the hazards.
(2) For each hazard, evaluate its severity level.
(3) Identify the hazardous situations.
(4) For each hazardous situation, determine the different system activities and their generated hazard.
(5) For each hazardous situation, evaluate the likelihood of its occurrence.
(6) For each hazardous situation, evaluate the targeted safety risk level based on its hazard severity and the likelihood of its occurrence.
(7) For each hazardous situation, decide the safety risk treatment: avoid, reduce, retain or share.
(8) For each hazardous situation, if the safety risk must be reduced, then identify the safety system functional requirements and/or the safety system non-functional requirements and/or the safety system constraints.
(9) For each hazardous situation, evaluate the safety residual risk level after treatment.
(10) For each hazardous situation, determine if the safety risk treatment leads to a threatening situation in the same context.
