Common causes. A gas explosion occurs when the gas/air mixture reaches a critical value, then any spark, flame or heat source can ignite the mixture. The explosion is caused when the rapidly expanding, burning gas is confined and builds up pressure. As the pressure builds, something has to give, and in a home gas explosion it is usually the windows.
Signs of a gas leak include: 1  A sulfur or rotten egg smell. 2  A hissing, whistling or blowing sound near gas appliances or pipes. 3  Dead, dry or discolored grass and vegetation near the gas line.  Dirt or water being blown into the air near a gas 1  line. An exposed pipeline after a natural disaster such as a flood or earthquake.
