HSSE in Scenarios & Risk
What could go wrong, how likely, how bad, and why the risk is tolerable
What sits here
How major accident scenarios are identified and analysed, including harm to the environment and effects on neighbouring sites, and the basis on which risk is judged as low as reasonably practicable. A change of method or criterion can change every conclusion that rests on it.
