The new ones don't allow you to fill them all the way, which should reduce the possibility of over pressuring. Although we once had a neighbor who through a couple of the smaller empty one's (the kind used for propane torches) into a brush pile... then lit it off! The ground shook for at least a one block radius, The neighbor and his two grown boys were showered with burning branches and debris, but were miraculously left unharmed.
Some years ago, the refinery insisted on rotational assignments to the Fire Brigade.... Lightning struck one of the propane spheres(picture a ball the size of a five story building) which set off the relief valve and started it on fire under pressure! Every one looked out into the pouring rain at the "torch" atop the sphere, and insisted that it must be some one else's turn to respond.
The Relief Valve automatically reset and the very next week the company asked for volunteers and formed a Fire Brigade!
I think that melon is both safe and cute, although you seldom see them placed so close to the house.
It is still illadvised to dispose of propane cylinders in a fire!
