Example for risk reduction: selection ofconstruction materialsSuitable material is not subject to unexpectedmaterial related failures during the calculated plantlifetime under nominal operation conditionsCalculated plant lifetime: ~15-20 YearsNominal operation conditions:– Specified cases of operation– Design pressure and temperatures, fluidcomposition, flow velocity as specified– Start up– Shut down– Site condition47Example for risk reduction: fire andexplosion protectionProper selection of mechanical equipment to avoidleakagesExplosion proof electric equipment and instrumentationGas detection systemsSteam curtains (e.g. for the furnaces)Closed blow-down systemSafety distances between plant sectionFire proofing insulationFire water systems including hydrants and monitorsWater spray systems48
