2	Setting up and connecting of test manifold, nitrogen cylinder, hoses to  to pipe system	·     Tools are inappropriate, defective, and fabricated ·     Hoses obstructing access ways	M	·   Ensure that all hand tools are properly inspected with current monthly color code. ·   Supervisor shall ensure that all tools are in the standard prior to its use. Fabricated tools are not allowed to be used. ·   All workers shall wear the appropriate PPE at all times. ·   Access to the work locations shall be clear and free from any obstruction. ·   Manifold must accordance in client pressure testing standards and requirements and obtained valid testing certificate. ·   Manifold should be mark with testing pressure capacity, indemnification number and other details	L	Task supervisor Worker
3	Line pressurizing	·     Loose /not properly tightened connections ·     Un-calibrated test manifold and gauges ·     Unavailability of whip lash installed on hoses connections ·     Nitrogen leak	M	·   Supervisors shall ensure that all connection is properly tightened. ·   Work notification shall be convey to all affected and responsible departments. ·   All affected area will be provided with barricade and appropriate, safe distance shall be in accordance with LLOYDS’s Registry Standards. ·   Pressurization shall be stop immediately and pressure shall be gradually reduced to zero gauge reading in case of pipe failure. Nitrogen cylinder valve shall also be immediately turned off ·   Pressurization shall be immediately cancelled when a leak is detected. ·   Workers shall immediately vacate the area when leak is observed. ·   Only approved and calibrated gauges shall be used for the test. Calibration shall be done within one month of the test and the ranges shall be 30 to 80% of the gauge’s full range. ·   There shall one pressure gauge installed on both the manifold and system under test. ·   Test manifold shall be tested separately to 1.2 times of actual test pressure. Valid 3rd party certificate shall be attached with the test package. ·   Relief valves shall be tested, dated, and tagged within 1 week prior the testing ·   All hoses connection shall be tight and secured by whiplash arrestor ·   Rated capacity of hose shall be more than the test pressure ·   Testing crew shall obtain required training for pressure testing. ·   There shall be a person dedicated to monitor the pressurization progress ·   Holding pressure shall be as per the test procedure approved by Client ·   A person shall be assign to operate the outlet valve of the nitrogen cylinder. ·   All workforces shall be aware on potential hazards in exposed of nitrogen such as frostbite and displacement of oxygen amount.

4	Leak Checking	·     Unauthorized personnel	M	·   Trained and authorized crews only are allowed to do the leak inspection. ·   Observation to be made away from the joints. At any cost do not stand in front of the end joint. ·   If any leak observed, immediately reduce the pressure to zero. ·   Reduce the pressure to design pressure before start the leak checking	L	Task supervisor Worker
5	Depressurizing	·     Untimely release of pressure	M	·   Open the vent valve slowly until the pressure was reduced. ·   Coordinate with the other worker. Give notice prior the release of pressure ·   Task supervisor to ensure no person in line of fire at vent area.	L	Task supervisor Worker
