What should you never use to check for gas leaks?

Using a flame to check for gas leaks is extremely dangerous because it poses an immediate risk of ignition. Gas leaks can result in highly flammable situations, and introducing an open flame can lead to explosions or fires, causing severe damage to property and risk to life. It is essential to use safe methods to detect gas leaks, such as a soap solution, which creates bubbles when gas is present, or electronic detectors designed specifically for leak detection. A pressure gauge can also measure the integrity of the system without introducing any ignition sources. Safety protocols clearly dictate that flames must never be utilized in situations involving flammable gases due to the associated risks.
