Video: Identifying Gas Shut-Off Valves and Their Position
This video demonstrates how to locate gas shut-off valves and determine whether they are in the on or off position.
Overview
Gas shut-off valves control the flow of natural gas or propane to a home or to individual appliances. Knowing how to identify valve positions allows you to quickly stop gas flow in an emergency and safely confirm appliance operation.
Gas shut-off valves are used for both whole-house supply and individual appliances.

Emergency Gas Shutoff
In an emergency, the video emphasizes:
Turning off the gas supply immediately
Avoiding use of electrical switches if gas is suspected
Contacting maintenance or emergency services promptly
Troubleshooting
Valve difficult to turn → Do not force it
