When your range leaks gas, it could be dangerous. One of the biggest problems that you not always could define that range leaking gas, because of the small volume of gas. So if you suspect that range is leaking gas, you can make a few things to detect gas leaking and call service, to fix that problem. While you are waiting for service - make a bubble test.
Classic method to detect a gas leak is the bubble test. To perform the test, all you need to do is to mix a small amount of dish soap or detergent with water, turn on the gas, and
use a wet sponge or cloth to wipe it along the gas pipes. If you see bubbles, there’s a leak. The bubbles are caused by the leaking gas that is pushing through the water-soap mixture. Turn off the gas and avoid using the stove before the leak has been fixed.
Using acetate test strips is a fairly cheap and easy way to detect a gas leak. If you use lead acetate test strips and move them near the suspected leak, the strip will change colour. This method is very commonly used in the oil drilling business as well.
If there’s a suspected gas leak, your priority is to evacuate everyone in the house. Apart from ensuring their safety, this also prevents them from inhaling more gas which puts them at risk for gas poisoning.
