Using a soapy water solution is a valid method for detecting propane leaks because it creates bubbles when it comes into contact with escaping gas. This visual confirmation allows technicians to locate leaks accurately. When soapy water is applied to the suspected areas, any leakage will cause the liquid to bubble up, which is an immediate indication of the presence of propane.

While gas detectors are also effective, they primarily rely on electronic or mechanical systems to sense gas, which may not always be practical in every situation. The method using a match is dangerous and can lead to explosions. Relying solely on the smell test, while common due to the distinct odor added to propane, is not always reliable because a person's ability to detect odors can vary, and in some cases, the scent may be masked by other environmental factors. Thus, the soapy water solution remains a preferred, safe, and reliable method when checking for propane leaks.
