Yes, the released oxygen will intensify the fire.
NO the cylinder landing on its regulator will not cause EXPLOSIVE decompression. If it were to braeak the fill value area it would take off like a rocket, but not explode.
I have been in very intense fires where cylinders filed with flammable gases were venting into the fire area and burning, and even gas meters on the walls inside of houses.
You cool it down it stops venting, it takes a lot to cause a cynlinder to rupure.
