How safe is to own a propane tank or bottle?

Main concerns: He read the propane (camping) bottle about how to store it.  The label on the bottle says: store in a cool place under 120 degrees (F).  He said that he put the bottle in his garage, but his garage can be hotter than 120 degrees.

Answer: It is true that we should not store a propane bottle anywhere above 120F.  Since inside house is the coolest place compared to yard and garage, storing propane bottle inside house maybe the safest way. Consider a few excerpts of an article “A Safe Fuel” from National Propane Gas Association

  • “A propane tank is 20 times more puncture resistant than a typical gasoline, methanol or ethanol tank.” 
  • “Propane with air won’t ignite unless the source of ignition reaches at least 940 degrees Fahrenheit. In contrast, gasoline’s source of ignition must reach only 430 to 500 degrees Fahrenheit before igniting.”

Then the question to ask ourselves is: since we park our cars in our garage too, will the gasoline tanks in our cars get into trouble earlier than a propane bottle/tank? For more safety information, we recommend to visit the National Propane Gas Association web site
