The Hazardous Incident Ordinance mandates operators to take necessary precautions to prevent incidents. Systems should align with the latest safety technology. PCT safety devices are viable if other measures are ineffective or not cost-efficient with similar risk reduction. The seminar will cover VDI/VDE 2180 guidelines, offering insight into functional safety. VDI/VDE 2180 is applicable to process industry systems and fulfills the requirements of the 12th BImSchV for PCT safety devices. The seminar defines methods for identifying risks and determining the Safety Integrity Level (SIL). It also provides a comprehensive explanation of functional safety and calculation options for PFD values.
