Question: 1 / 400

When operating a boiler, what pressure is defined as "Low Pressure"?

Less than 5 psig

15 psig or less

In the context of boiler operation, "Low Pressure" is typically defined as being at 15 psig or less. This definition is widely accepted in various regulatory and industry guidelines, establishing a clear threshold that separates low-pressure systems from higher-pressure systems.

Boilers operating at low pressures are subject to different operational parameters, safety regulations, and maintenance requirements compared to those functioning at higher pressures. Operating within this low-pressure range generally allows for a simpler design and less stringent safety measures, reflecting the reduced risks associated with lower pressure systems.

Understanding this classification is key for those responsible for operating or managing boiler systems, as it informs decision-making regarding equipment selection, safety protocols, and compliance with local regulations.
