Natural gas has a flammability range of approximately 5 to 15 percent. That means that any mixture containing less than 5 percent or greater than 15 percent natural gas to air would not support combustion. Natural gas, when mixed with air and exposed to an ignition source, is combustible.
Can natural gas lines explode?
Although the natural gas industry is heavily regulated, pipeline explosions still occur. Many of these explosions can be traced to human error in one way or another. The U.S. Occupational Health and Safety Administration (OHSA) extensively regulates pipeline safety throughout the United States.
Can natural gas explode without fire?

Will a natural gas leak kill you?

Why is natural gas dangerous to life?
