What is the difference between high-pressure and low-pressure gas systems?

High-pressure gas systems are defined as those that operate above 0.5 psi, while low-pressure systems operate at pressures below that threshold. Understanding these pressure classifications is crucial for safety and efficiency in gas management. High-pressure systems may be used in applications requiring a more robust gas supply, typically involving pipelines that transport gas over long distances or in situations where rapid gas delivery is necessary.

In contrast, low-pressure systems are commonly utilized for residential and commercial applications, where the demand for gas is less intense, allowing for safe and efficient operation at lower pressures. Recognizing this distinction is essential for technicians when assessing system requirements and ensuring appropriate equipment and safety measures are used.

The other options do not accurately represent the relationship between high and low-pressure systems, which is fundamentally based on the pressure thresholds established in their definitions. Therefore, understanding the specific operational pressure ranges for high-pressure and low-pressure systems is key to safe and effective gas handling practices.
