Home Gas Detection

Natural gas can exist in rock and soil. These gases can filter into buildings and homes. A home gas detector can measure the amount of gas in a home’s air. When selecting a home gas detector, make sure:

  • The detector meets UL Standard 1484 for residential gas detectors
  • It plugs in to a standard outlet and has a backup battery in case of power loss
  • All manufacturer’s directions are followed and include:
    • Detailed directions for proper installation
    • Detailed instructions for how to respond to the alarm
  • The detector is replaced at least as often as manufacturer recommends (often up to five years)

  • First Alert Plug-In Explosive Gas and Carbon Monoxide Alarm with Digital Display
  • KIDDE KN-COEG-3 Nighthawk Plug-In Carbon Monoxide and Explosive Gas Alarm with Battery Backup
