Because there are different gas shut-off procedures for different gas metre configurations, it is important to contact your local gas company for any guidance on preparations and response regarding gas appliances and gas service to your home.
When you learn the proper shut-off procedure for the metre, share the information with everyone in your household. Be sure not to actually turn off the gas when practicing the proper gas shut-off procedures.
If you smell gas or hear a blowing or hissing noise, open a window and get everyone out quickly. Turn off the gas, using the outside main valve, and call the gas company from a cell phone outside your home.
Before an emergency happens, locate the shut-off valve for the water line that enters your house and label this valve with a tag for easy identification. Make sure this valve can be completely shut off. Your valve may be rusted open or it may only partially close. If so, replace it.
Electrical sparks have the potential of igniting natural gas if it is leaking. It is wise to teach all responsible household members where and how to shut off electricity. Locate your electrical circuit box. For safety, shut off all the individual circuits before shutting off the main circuit.
