• Propane tanks are made of carbon steel and therefore are 20 times more puncture resistant than tanks filled with ethanol, methanol or gasoline. Propane tanks are developed by the American Society of Mechanical Engineers.
• Propane cylinders are equipped with a safety device that cuts off the filling process when the tanks has reached its liquid capacity.
• Propane has the lowest flammability rating of any alternative fuel. Propane will not ignite until it reaches 920 degrees F, while gasoline’s ignition temperature is 430 to 500 degrees F.
• Propane is tasteless, colorless and odorless, and therefore as a safety measure, an odorant is added that smells like rotten eggs.
