One of the most dangerous situations which can produce an explosion hazard in your home, is an empty house where all occupants are out and all doors and windows are closed. Meaning no one will be there to smell the gas leak or hear the alarm, even if RMDs are present. Nobody will be there to take action to notify first responders and your gas utility company.

You simply have a ticking bomb waiting for the inevitable: When the first home occupant returns home at night, the first thing most of us do is to automatically turn on the light even before noticing any smell. And that is all an explosive gas present in the air in enough concentration needs to detonate and in most cases level the house causing severe property damages not to mention death
