Read a story from Florida. A mom in her back yard used a gas can to pour gas on a big log in a outdoor fire pit. The flame traveled up the descending stream igniting the can and exploding. It killed her and severely injured her 11 year old. Very sad. Gasoline is very explosive. The liquid emits fumes like a mini gas cloud. These fumes are what causes the rapid explosion.
Every once in awhile you read about a house being blown to bits in a gas explosion. The house fills with natural gas from a leak in a pipe and can be ignited by turning on a light switch. When you turn on a switch a small spark is generated.
Also you may want to install a carbon monoxide detector in your house for about 25 dollars. Also get a smoke detector. This gas (CO) is generated by burning of fossil fuels. It is odorless. It can kill you.
In life we have an opportunity to learn from other people's mistakes. Think and then act on it. We can learn either the hard way or the easier way. Listen to that small inner voice you have, it just might save your life.
