Where should a readily accessible shut-off valve be installed?

A readily accessible shut-off valve is crucial for ensuring safety and emergency procedures in gas systems. Installing the shut-off valve close to the valve train of the appliance allows for quick access in case of a leak or an emergency situation. This proximity ensures that the gas supply can be shut off immediately, minimizing the risk of an explosion or fire.

By positioning the valve near the appliance, it also allows for easier operation during maintenance or when servicing the appliance. Accessibility is a primary concern, as the ability to quickly turn off the gas supply can make the difference in preventing an accident or managing a hazardous situation effectively.

In contrast, having the valve at the main gas line or in the basement may not provide the same level of accessibility, especially in urgent scenarios where rapid response time is critical. Additionally, placing the valve as far from the appliance as possible would defeat the purpose of having an easily reachable shut-off option.
