Post warning notice.
Ensure the equipment / tool to be used for hydro – testing (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 hydro-tested.
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.)
Ensure the workers are wearing required PPE.
Never increase the hydro-test pressure more than the maximum allowable pressure for the weakest portion in the segment or pressure rating of the hose & coupling.
Do not leave the pressurized hose or pump unattended when the hydro-test is going on.
Isolate the equipment from all source of energy when not in use.
Changing the Duration of Hydro-test
Do not change (exceed / decrease) the duration of hydro-test without permission from Inspection Engineer.
