How can you identify a gas leak during a safety inspection?

Identifying a gas leak during a safety inspection is crucial for ensuring the safety of individuals and property. The most reliable method involves using a gas leak detector or performing a soapy water test. This method is effective because when gas escapes from a leak, it will come into contact with the water solution, which creates bubbles that indicate the presence of gas. This visual cue makes it a straightforward and reliable approach for detecting leaks without risking combustion or other hazards.

Using a flame to test for gas presence is extremely dangerous; it poses a risk of igniting any gas that might be escaping, leading to potentially catastrophic consequences. Observing unusual appliance performance might suggest there is an issue with the appliance, but it does not definitively confirm a gas leak. Similarly, looking for oil spills near the appliance is unrelated to gas detection since gas leaks would not produce oil spills. Thus, relying on a gas leak detector or soapy water test is the safest and most effective method for identifying a leak during a safety inspection.
