What is the maximum design operating pressure for piping systems located inside buildings?

• A. 10 PSIG
• B. 5 PSIG
• C. 15 PSIG
• D. 20 PSIG

Answer: (B)

The maximum design operating pressure for piping systems located inside buildings is 5 PSIG. This limit is established to ensure safety in enclosed environments where higher pressures could pose significant risks, such as leaks or ruptures, which would be exacerbated in confined spaces. By regulating the pressure to a maximum of 5 PSIG for indoor systems, the potential for dangerous situations is greatly minimized. Understanding this limitation is crucial, as it helps professionals adhere to safety standards and realize the importance of proper pressure management in the design and maintenance of gas-piping systems within buildings.
