Recommendations

           1.  Passing valve at DHDS B/L to be replaced in the earliest opportunity. Also, provision of double valve may
              be looked into.
            2.  All other passing valves to be replaced.

            3.  Presence of pyrophoric iron and its mitigation measure to be included in the hazards while doing this
              activity as the flange is located closer to the Chloride guard.
            4.  Continuous Nitrogen purging shall be ensured, in case job is being carried out on Passing valves of
              H/C, or combustible gas.
            5.  Ensure critical jobs pertaining to Hydrogen services shall be analysed with JSA.
