What Is a Gas System Riser Diagram?
Medical gas pipeline mapping is required by regulatory agencies. CAD schematics, or "riser diagrams," trace the paths that the piped medical gases travel from their sources, through the facility, and into ICUs, ORs, and other patient care zones. A large color printed riser diagram showing shutoff valve locations and the areas they control is vital for both emergency and maintenance system shutdowns.
How Is the Riser Diagram Produced?
- Shutoffs and accessible piping are labeled as the piping is traced.
- Pipe sizing is documented and labels affixed to valves and piping during tracing.
- A CAD drawing is produced to indicate piping, source equipment and valves throughout the facility.
- A large-scale color print is mounted in the engineering shop so valves can be quickly located and shut off in the event of an emergency.
Why Is Medical Gas Drafting Needed?
A CAD schematic ensures compliance and safety. In fact, TJC (The Joint Commission) standards require schematics for all medical gas system shutdowns. The riser diagram reduces the time required during shutdown preparation by helping you quickly identify valve locations and the areas they control. The diagram is useful not only during planned shutdowns, but also during a fire or other emergency when it can save the lives of patients and employees.
