A series of underground or aboveground pipeline valves controls transmission pipelines and most distribution mains. These include relief valves, mechanisms that vent excess gas and vapors and when actuated, protect the pipeline system from overpressurization. Only trained gas pipeline representatives or utility personnel should operate these and other system valves. Never attempt to open or close underground or aboveground pipeline valves. Doing so could damage the valves and cause dangerous pressure changes or outages in the system.

If necessary, first responders may close aboveground shutoff valves at meters or appliance supply lines. After a gas valve is closed, contact LG&E and KU immediately. Only utility personnel may restore gas service.
