- (a) Each pressure vessel shall be protected by such safety devices, including relief valves and rupture disks, as will ensure its safe operation.
- (b) These valves and devices shall be so constructed, located, and installed that they cannot readily be rendered inoperative.
- (c) The relieving capacity of the safety devices shall be such as to prevent a rise of pressure in the vessel of more than ten percent (10%) above the maximum allowable working pressure, taking into account the effect of static head pressure.
- (d) Safety device discharges shall be to a safe place.
- (e) Device outlets shall not be reduced, and device header piping should not rely on the device body for its support.
