“Create an event tree for a toxic chemical release with gas detection, secondary containment, and emergency response barriers, ending in contained exposure, offsite response, onsite exposure, or uncontrolled exposure.”
Lee las decisiones que hay detrás.
Detection begins the response sequence.
Secondary containment limits spread before responders intervene.
Emergency response is considered only where it can still alter the outcome.
Use for a workshop-level hazard assessment and supplement it with site-specific consequence modelling.
Preguntas habituales
What is secondary containment?
It is a physical feature such as a bund, dike or enclosed drain that limits the spread of released material.
How should barriers be ordered?
Order them by when they can affect the scenario, from detection through physical mitigation and response.
Can outcomes include people and environmental effects?
Yes. Name the outcome so it describes the consequence your assessment needs to compare.
