What should be done if leakage is indicated during a gas test?

When leakage is indicated during a gas test, shutting off the gas supply is the appropriate course of action to take. This step is crucial for ensuring safety and preventing potential hazards associated with gas leakage, which may include fires, explosions, or harmful gas exposure to individuals in the vicinity.

Quickly shutting off the gas supply minimizes the risk of further leakage and allows for safe inspection and remediation measures to be taken. Once the gas is turned off, a thorough investigation can be conducted to identify the source of the leak and address it properly.

The other actions—ignoring the leak, continuing the test, or simply reporting it to authorities—fail to prioritize immediate safety. Ignoring a leak could lead to dangerous situations, while continuing testing without addressing the leak poses significant risks. Reporting to authorities may be necessary after ensuring the area is safe, but it should not replace the immediate response of shutting off the gas supply.
