What is the explosive range of natural gas by volume?

The explosive range of natural gas by volume is accurately defined as 5% to 15%. This range indicates the concentrations of natural gas in air that can ignite and result in an explosion when there is an ignition source. When the concentration of natural gas falls below 5%, there is insufficient fuel to support combustion, while concentrations above 15% become too rich for combustion to occur.

Understanding this explosive range is essential for safety when handling natural gas, as it helps responders recognize the potential for explosive environments and take appropriate precautions when assessing situations involving natural gas leaks or accumulations. The focus on the 5%-15% range assists personnel in determining the necessary safety measures and strategies for containment, ventilation, or evacuation in the event of a gas leak.
