Implementation of the 12th BImSchV (Hazardous Incident Ordinance) by verification of a safety integrity level (SIL) at process control engineering devices

Hazardous incidents can reasonably be excluded by precise control, measurements, regulation, supervision, reporting and registration. For this purpose, evidence has to be provided that a specified safety integrity level (SIL) for an existing or planned technical implementation of a process control safety device (sensor part, logic part and actuator part) is achieved. Müller-BBM supports plant operators in providing evidence according to VDI/VDE 2180 sheet 3 with regard to structural requirements (verification of hardware fault tolerance) as well as the calculation of probabilities of default of process control safety functions.

The inspection with different test intervals and inspection depths as well as their effects on the probabilities of default as given in the guideline VDI/VDE 2180 sheet 3 “Nachweis des Sicherheitsintegritätslevels (SIL) (Verification of the safety integrity level)“ is based on on sheet 1 “Einführung, Begriffe, Konzeption (Introduction, terms, conception)“ and 2 “Planung, Errichtung und Betrieb von PLT-Sicherheitseinrichtungen (Planning, construction and operation of PCE safety devices)“.

In particular for planners, operators and users of operating equipment of the process industry, the application of the guideline, based on DIN EN 61611, is a reliable way to implement the requirements of the Hazardous Incident Ordinance on process control devices with safety functions.
