Should high-pressure fuel gas piping over 5 psi be installed in vertical chases within a building?

High-pressure fuel gas piping over 5 psi should not be installed in vertical chases within a building primarily due to safety and code compliance considerations. Installing such high-pressure gas lines in enclosed vertical spaces can pose significant risks. These areas are often difficult to access for maintenance, which could hinder the ability to respond quickly to potential leaks or failures.

Furthermore, local building codes and safety standards often prohibit the installation of high-pressure gas piping in vertical chases because these confined spaces can create a hazardous environment if there is a leak. Gas that escapes can accumulate in the chase and lead to dangerous situations, including the risk of explosion or fire. Therefore, it's essential to follow guidelines stipulating that these high-pressure pipes are installed in more accessible and ventilated locations to ensure safety and allow for adequate monitoring and maintenance.

By adhering to these safety regulations, potential hazards associated with high-pressure fuel gas systems can be significantly reduced, ensuring a safer environment for building occupants and maintenance personnel.
