Which of the following low pressure levels typically classifies a gas line?

A gas line is typically classified as low pressure if it operates within the range of 1 to 5 psi. This classification is important for the installation, maintenance, and regulation of gas systems, as it helps determine the appropriate materials and safety procedures required for safe operation.

In the context of gas distribution, lines operating below 5 psi are generally considered safe for residential and light commercial applications where natural gas is used for heating, cooking, and other purposes. Lines within this low-pressure range allow for the use of less robust piping materials and fittings, which can be sufficient for these applications.

Understanding the standards for low pressure is crucial for gas technicians, as it guides them in adhering to safety codes and ensuring that installations meet the necessary regulatory requirements. This classification helps to ensure that systems are designed appropriately to prevent leaks and function efficiently.
