The signs of a gas leak are usually quite obvious and straightforward, so it’s not likely that you will mistake them for something else. In reality, there is only one telltale sign and it is a strong smell of rotten eggs. The gas itself is odorless, but the offensive smell is added so homeowners and the general public will know when there is a leak. If a gas line has been split or ruptured, you might also hear a hissing noise as the gas escapes from the line. Either of these signs requires swift action.
The first thing you should do when you suspect a gas leak in or around your home is to get everyone out of the area. Don’t shut off lights or use any appliances, just evacuate to clean air and away from the potential hazard. Next, you should call for professional help to see if you are in fact dealing with a gas leak, and if you are, to have it repaired. Professional gas leak detection will help pinpoint the location of the leak, so it can be repaired quickly and safely.
