Care for your pipes. If you’re excavating outdoors, don’t dig until you have your utility company flag where the lines are. Don’t use basement pipes to hang heavy items, and make sure the gas connections to your stovetop range and other gas appliances aren’t fraying or cracked. By law, “gas pipes leading into a concealed area should be labeled gas, but this isn’t always the case,” says Bob Kordulak, a code secretary for the Plumbing-Heating-Cooling Contractors National Association. For extra peace of mind, you could install a natural-gas detector, which detects methane and propane gas leaks (ask your local utility company for recommendations). Still, your nose is your best system of detection.
Educate the family. Make sure every family member knows the basic rule of gas safety: that anytime they smell an unmistakable rotten-egg odor or hear a hissing sound and can’t immediately identify the source, they should get out of the house.
