Pressure build-up/Ice plug formation. Due to the large expansion ratio (liquid to gas), if LN 2 is evaporating within a closed system, the pressure can build up with a high risk of explosion. Ice plugs can form on the neck of narrow storage vessels if there is no relief vent, as water is readily condensed by LN 2 to form ice.
