Does SDG&E have any information about Carbon Monoxide (CO) detection devices?
Make sure that the detector you select has an audible alarm, one you can hear. We recommend that you consider only those devices tested and certified by reputable consumer groups like the American Gas Association or Underwriters Laboratory. Be sure to buy a device that has a battery backup and warns you if the battery is low or the device isn’t working properly. And remember, a CO device is no substitute for a well-maintained gas appliance.
