Why should you avoid using a match to check for leaks?

Using a match to check for leaks is extremely dangerous because the flame can ignite the gas that is leaking. Natural gas and propane are highly combustible, and even a small spark can trigger a fire or explosion in the presence of flammable vapors. This poses a significant risk not only to the individual performing the check but also to anyone nearby and to the surrounding environment.

When checking for gas leaks, safer methods exist, such as using a soap solution or a gas leak detection fluid which will produce visible bubbles at the site of a leak. These methods are non-flammable and provide a reliable means of identifying leaks without the risk of igniting gas.

In contrast, using a match does not provide any advantage in detecting a leak accurately either. The main priority in handling combustible gases is safety, and using open flames undermines that principle. Therefore, avoiding matches when checking for leaks is essential to prevent catastrophic consequences.
