When is a piping system classified as 'non-hazardous'?

A piping system is classified as 'non-hazardous' primarily based on the nature of the fluids it carries. When the system transports fluids that do not pose environmental risks, it is deemed non-hazardous. This classification is critical because it helps in determining the appropriate safety measures and regulations required for handling and maintaining the piping system.

In contrast, the presence of flammable liquids, the location of installation, or the pressure metrics do not by themselves define the hazard status of fluids within the piping system. For example, flammable liquids are inherently hazardous due to their potential to ignite and cause fires. Additionally, while residential areas may often have less stringent requirements compared to industrial zones, that does not automatically classify the system as non-hazardous. Lastly, the pressure of a system exceeding 100 PSI does not relate specifically to the hazard classification of the fluid it transports; rather, it may indicate the need for different materials and practices to handle the system safely.
