675 IAC 30-11-4 Safety appliances

Sec. 4. Each unfired pressure vessel shall be protected by such safety and relief valves and interlocking, indicating, and controlling safety devices as will ensure its safe operation. These valves and devices shall be so constructed, located, and installed that they cannot readily be rendered inoperative. The relieving capacity of safety valves shall be such as to prevent a rise of pressure in the vessel in excess of that permitted by applicable provisions of the API-ASME code or the ASME B&PVC, taking into account the effect of static head. Safety valve discharges shall be carried to a point where damage to property or injury to personnel is minimized.
