What should be the position of the manual shut-off valve relative to the equipment?

The manual shut-off valve should be visible and accessible to ensure that it can be easily located and operated in case of an emergency or maintenance need. This positioning is vital for safety, as it allows quick access to shut off the gas supply to the equipment when necessary, preventing potential hazards like gas leaks or fires.

Being visible ensures that service personnel or anyone operating the equipment can identify the shut-off point without delay. An accessible valve means that it can be operated swiftly, which is crucial in emergency situations where every second counts.

In contrast, positioning the valve in hidden locations, above, or below the equipment could complicate access, leading to delays in emergency response or routine maintenance, ultimately compromising safety standards.
