Safety Case · What could go wrong, and why the risk is tolerable
Major accident hazards and risk
Purpose
How major accident hazards are identified, how risk is evaluated, and the criteria against which the case argues that risk is as low as reasonably practicable. A change to a method or a criterion can change every conclusion that rests on it.
The question this lens asks
“If this document changed, would the safety case need to be revised and accepted by the competent authority before the change could be made?”
