Safety instrumented system SIS (SAFETY LOOP)
- As a rule, alarm equipment performs a safety protection function on machines and systems. Therefore, the consequences of an error in the signaling devices always present a potential risk if not seen.
- A hazard graph is not only an important element for the classification of the system or plant, it also clearly illustrates how complex the preliminary work is for the realisation and implementation of projects.
Since 1st June 2015, the European Directive, Seveso III, has been implemented as national law. In Germany, this occurs with the Amendment to the Hazardous Incident Ordinance (12 BlmSchV). Official, government inspections and monitoring will have even more influence in the new Hazardous Incident Ordinance.
Basic obligations are to take precautions to prevent hazardous incidents and the possible consequences thereof. This includes equipping the operating area with sufficient warning, alerting and safety facilities. For many years Pfannenberg has provided SIL/PL compliant signaling technology for harsh industrial environments. Equipped with the key safety data, the sounders and flashing lights can be integrated in the safety concept of machines and plants without any problems.
