Methane

Methane (CH₄) is a colorless, odorless, and highly flammable gas. Because it has no natural scent, utilities add odorants such as mercaptans to natural gas, creating the familiar “rotten egg” smell that helps people recognize a leak. As the primary component of natural gas, typically 70–90%, methane is widely used for heating, power generation, and industrial combustion, and it’s commonly present in boiler rooms, mechanical spaces, and fuel handling areas. Since methane is lighter than air, it rises and can accumulate near ceilings, making a natural gas leak detector essential for preventing fire and explosion hazards. Methane safety is equally important in kitchens and food service environments. Commercial kitchens rely on natural gas appliances such as stoves, ovens, fryers, and grills. Small leaks from fittings, burners, or supply lines can create dangerous accumulations. Installing a methane gas detector or CH₄ sensor provides early warning of leaks, helping protect staff, customers, and property. Beyond fossil fuel sources, methane is also produced biologically. Biogas and landfill gas form through anaerobic digestion and the breakdown of organic materials. As these renewable energy sources expand, the need for reliable biogas methane monitoring has grown significantly, particularly in wastewater treatment facilities, agricultural digesters, and renewable energy operations.
