Planning
Non-compliance with CMES and Facility’s HSE MS procedures Unauthorized personnel. Defective tools/equipment.
Obtain a cold work permit and other associated permits from Chevrons facility operators. Conduct tool box talk. Barricade the area where hydro-test is to be carried out. Post warning notice. Ensure the equipment/tool to be used for hydro-test (such as hose, pump, coupling, pressure gauge, spade, gasket etc) are free from defect and suitable for the pressure rating of the system.
Ensure the pressure relieving device is set at maximum allowable pressure for weakest portion of the segment to be hydrotested. Keep away from the pressurized segment of the system being hydro-tested. Monitor the pressure gauge from a safe distance away from the potential source of high pressure jetting (such as flange joint, spade and coupling etc). Do not leave the pressurized hose or pump unattended when the hydo-test is going on. Isolate the equipment from all source of energy when not in use. Do not change (exceed/decrease) the duration of hydro-test without permission from the inspection engineer. Ensure the safe depressurization of hydro-test fluid.
