Do carbon monoxide detectors detect natural gas

How to Detect Natural Gas Leaks?

Since natural gas is mostly methane, you need:

• Natural Gas Detectors – These are designed to detect methane and sometimes other combustible gases (like propane).
• Combustible Gas Detectors – Some devices detect multiple flammable gases, including methane, propane, and butane.

Why Doesn't a CO Detector Sense Natural Gas?

• Different Gases: CO is a byproduct of combustion, while natural gas (methane) is a fuel.
• Different Sensors: CO detectors use electrochemical sensors, while natural gas detectors use semiconductor or catalytic sensors.
• Safety Focus: CO is odorless and deadly at low levels, while natural gas is typically odorized (with mercaptan) for leak detection.

What to Do If You Suspect a Gas Leak?

• Smell: Natural gas has a rotten egg odor (added for safety).
• Hear: Hissing sounds near gas lines.
• Act: Leave the area, avoid sparks/flames, and call your gas company or emergency services.
