Low-pressure storage tanks require both vacuum- and pressure-relief devices,since these vessels typically are not designed for full vacuum.Relief devices for these tanks are designed only for vapor relief and not for liquid discharge due to overfilling instrumentation and/or procedural safeguards are used to mitigate the overfilling scenario.September 2017 VENTING GUIDEexcessive internal pressure or vacuum during normal storage and operations.Pressure Relieving Devices Defined in NFPA 30 section 22.7.3.1,where entire dependence for emergency relief is placed upon pressure relieving devices,the total venting capacity of both normal and emergency vents shall be enough to prevent rupture of the shell
