text: The principle of the fusible plug is also applied to the transport of liquefied petroleum gases, where fusible plugs (or small, exposed patches of the containers' lining membrane) are designed to melt or become porous if too high a temperature is reached: a controlled release, at a typical temperature of 250 °F (120 °C), is preferable to an explosive release (a "BLEVE") at a higher temperature.
