What are HAZOP and QRA, and when are they done?
derived
A hazard and operability study and a quantitative risk assessment systematically identify process hazards and quantify the resulting risk. Given flammable gas and 250-bar storage they belong at the engineering stage, where they inform safety setbacks, fire design and PESO compliance rather than documenting a design already frozen.
