A gas leak often emits a distinct smell, similar to rotten eggs, due to the addition of an odorant called mercaptan to naturally odorless gases. This smell might not be constant as it can be influenced by air flow, the size of the leak, and the location. If you suspect a gas leak, it’s imperative to act quickly by turning off the gas source if safely possible, evacuating the area, and calling the gas company or emergency services from a safe distance.
