A mechanism for understanding the potential domino effects is to perform consequence and risk modelling. DNV GL’s Phast and Safeti software can be used for this purpose.Īn assessment of domino effects can be performed in seven steps: A domino effect is a hazardous event on one facility or installation causing failure of equipment on neighbouring facilities or installations leading to additional hazardous materials being released. A jet fire from facility A impinging on a pressure vessel located on facility B resulting in rupture of the vessel and release of hazardous material is an example of a domino effect. It can be described as a type of escalation.
