When using Blinding/Blanking or Disconnect and Misalignment as an energy isolation method for your PRCS, do these isolation points have to be secured in their safe position with a lockout lock or tagout tag? In other words,
Can I install a blind/blank and not tag it out in the field indicating that it is an energy isolating device associated with the entry into a PRCS?
Can I roll a spool piece and just leave it rolled and not put a lock or tag through a bolt hole to identify the disconnect and misalignment as an energy isolation method for my PRCS entry?
I think most would agree that when using Double Block and Bleed that the two (2) closed block valves have to be locked in their CLOSED position and the bleed has to be locked out or tagged out in the OPEN position. This method is very clear as OSHA has included the LOTO requirement in their definition…
