As I have written about numerous times… PRESSURE TESTING a process is not only a “good idea” – it is REQUIRED for those of us in the process safety world. It is a critical path in process safety, ensuring our “primary containment” system (e.g. piping) was installed properly and can withstand process pressures. But with these tests comes some inherent risks and as in the case of OSHA Case File #310715214, we see how catastrophic an error can be. We can also see why the piping RAGAGEPs require TWO (2) independent means to ensure the process piping circuit being tested is NOT over pressurized.
