Tips: Where should methane sensors be placed?

Methane sensors should be strategically placed in areas where methane gas buildup is likely to occur. Some common locations for placing methane sensors include:

• Near Gas Appliances: Install methane sensors near gas-powered appliances such as stoves, ovens, water heaters, furnaces, and boilers. These appliances are potential sources of methane leaks, especially if they are old or poorly maintained.
• Along Gas Pipelines: Place methane sensors along gas pipelines to detect leaks or emissions along the pipeline route. Monitoring methane levels at various points along the pipeline can help identify and address potential leaks promptly.
• In Industrial Facilities: Install methane sensors in industrial facilities where methane gas is used or produced, such as refineries, chemical plants, wastewater treatment plants, and agricultural operations. These facilities may have equipment or processes that produce methane as a byproduct, posing a risk of leaks or emissions.
• Confined Spaces: Install methane sensors in confined spaces such as basements, crawl spaces, tunnels, and underground vaults where methane gas may accumulate. Poor ventilation in these areas can lead to the buildup of methane gas, posing a risk of explosion or asphyxiation.
