Working safety whilst we are commissioning must our number one concern, it should be inherent in everything we do from the way we draft and prepare our procedures, how we assess risk and evaluate task safety analysis and my topic today manage isolations.
All companies will have a robust plan for safety management including permit to work, confined entry and management of hot work, we as a commissioning group need to extend those safe practices as best we can starting for me with energy isolation. Upon Handover or turnover of a system, we may inherit from the construction team isolation already in place, this may include locks on motor starters, isolation within a control cabinet, installation of slip blinds and perhaps spools removed. All these when transferred to us as commissioning than must be accounted for, so the commissioning team must instigate an isolation register.
At any one time the system owner must know where all the isolations are within their system, account for them and if at all possible visualise them for all to see with marked up P&ID’s, key boards, lock boxes, whatever it takes. As systems become live and we run into simultaneous construction and commissioning operations and as inter system commissioning commences, we must know where all our isolations are, so we keep each other safe, obviously robust communication of energy and commissioning status is required.
So let’s make sure creation of isolation lists for mechanical, electrical, instrumentation, radioactive sources, trace heating etc. is well managed, clear to understand and highly visible.
Safe and successful commissioning always…
