Would you be an entrant? (PRCS isolation)
You and your team are preparing to enter a PRCS, and as the entry supervisor begins to review the permit, he/she explains the space is isolated, and you notice the permit states "LOTO- N/A." You inquire about this and ask about the isolation method(s) used for the entry. The supervisor offers to show you the isolation for the vertical 100,000-gallon storage tank and to walk down the isolation with you. The first pipe/line you come to is a 6” fuel discharge pipe. It is isolated using a disconnect and misalignment arrangement that rolled a 3’ spool piece down. The next pipe you come to is a 6” fuel inlet pipe. It is isolated using a disconnect and misalignment arrangement that rolls down a 3’ spool piece. The third and last pipe is a 1” nitrogen pipe, and it, too is isolated using a disconnect and misalignment arrangement that rolled a 1’ spool piece down. You notice that NONE of the three disconnect and misalignment arrangements were locked or tagged in their safe position. When you ask about LOTO and where you and your team need to apply your LOTO lock(s), the entry supervisor says no locks are needed. Would you enter this tank? |
