Point-Level Switches for Safety Systems

By Bill Sholette, Endress + Hauser |

Industries that manufacture or store potentially hazardous materials need to employ point-level switches to protect people and the environment from spills Safety is an important and common subject of discussion in the chemical process industries (CPI) today. Conversations on safety include many topics, such as risk assessment, risk mitigation, and tolerable risk. Acronyms like SIS (safety instrumented systems), SIL (safety integrity level) and PFD (probability of failure on demand) and others have become part of the safety lexicon in CPI facilities throughout North America and the world. All of these terms and acronyms can be confusing, complicating what steps need to be taken to make a facility safe. Regardless of how the safety concepts are labeled, there are a few principles that form the basis for all safety models. Whether you subscribe completely to the SIS concept or have developed your own safety procedures internally, risk assessment and risk mitigation are the two key concepts in any safety model. Determining what may go wrong and then taking steps to reduce the possibility by adding safety procedures, retention dikes, safety instrumentation and so on, are universal to any safety program. The following are assessments…
