How should a gas valve be positioned for it to be in the 'open' position?

A gas valve is designed to control the flow of gas through a piping system, and its position indicates whether it is open or closed. The correct answer states that for a gas valve to be in the "open" position, the handle should be aligned with the pipe. This means that when the handle is turned so that it runs parallel to the direction of the gas flow (and thus the pipe), gas is allowed to pass through.

This positioning conveys to the user that the valve is open for operation. In contrast, when the handle is perpendicular to the pipe, it indicates the valve is closed, preventing gas flow. Therefore, the alignment of the handle with the pipe is critical for safe and correct gas service operations, ensuring that gas can flow freely when the valve is in the open state.

In other options, one mentions that the handle should be turned 90 degrees from the pipe; this would actually close the valve. Another asserts that the handle should be perpendicular to the pipe, which again indicates a closed position. The last option describes removing the valve to allow gas flow, which is impractical and unsafe, as valves are meant to control flow without the need for disassembly. Therefore, the alignment of the handle with the pipe is
