General Information ❑ Process Isolation including the following categories: ❑ Positive Isolation ❑ Process Isolated by Installing Rated Blind or Disconnecting Pipe. ❑ Considered as process isolation for Hot Work and/or Confide Space Entry. ❑ To verify that the isolation valves are holding, Bleeder must show no leakage. ❑ All valves shall be locked and tagged with a “Danger - Do Not Operate” tag. 61 Classification: Tasnee - General Information ❑ Process Isolation including the following categories: ❑ Proved Isolation ❑ Process Isolated by Double Block & Bleed method is Considered as process isolation for Cold Work only. ❑ Double Block & Bleed method is closing of two positives shut off valves and opening a bleed (vent/drain) valve in between. ❑ The theory behind this method is that if the first isolation valve fails, the material in the line would discharge through the bleed valve and not into the work area. ❑ In some cases, valves used for a double block and bleed may be remotely or automatically operated. ❑ In some cases, the energy supply (air, electricity, etc.) shall be disconnected and the position of the valve shall be assured by a spring, pin or other locking device. ❑ Isolation valves shall verify are properly holding and Bleeders must show no leakage. ❑ All valves shall be locked and tagged with a “Danger - Do Not Operate” tag. ❑ Safe maker shall visit the area frequently to check and ensure the isolation integrity. 62 Classification: Tasnee - General Information ❑ Process Isolation including the following categories: ❑ Isolation ❑ Process Isolated by Single Valve & Bleed is Considered for Cold Work in very limited cases where provision of Double Block & Bleed not available at asset and with satisfying protection and mitigation condition. ❑ Single valve with bleed method limited to be used for non-hazardous materiel (such as LP water, LP air, LP N2, etc.). ❑ In-case hazardous materiel involved and required to use this method then area owner approval is required. ❑ Single valve with Bleed limited as isolation for Cold Work activities ❑ Isolation valves shall properly hold, and Bleeder(s) must show no leakage. ❑ All valves shall be locked and tagged with a “Danger - Do Not Operate” tag. ❑ Safe maker shall visit the area frequently to check and ensure the isolation integrity and no hazards in the area. ❑ Repair jobs on equipment shall continue without interruption and without the technician leaving the equipment. 63
