A clogged sewer line may be the result of a cross bore with a gas line. Take precautions before any sewer cleaning. Ask your plumber or contractor to use a camera to assess the cause of the blockage and to clear the sewer using a plumbing snake or water jet rather than a cutting tool, which may damage gas lines.
During and after sewer cleaning, look out for potential signs of a gas leak.
