There is a scenario where anticipated flooding in a substation (over 600 V and not accessible to unqualified personnel) would lead us to sandbag around equipment to protect it. This would effectively raise the ground level and could break electrical clearances. According to 110.27 this would need to be guarded to prevent accidental contact. The action that we would take is to put in guards around the area to keep workers from standing on top of the wall. According to the second approved action we would have to install "suitable permanent, substantial partitions or screens so that only qualified personnel have access to live parts."
Since the sandbags are temporary what would the definition of "suitable permanent" guards be? I would assume we could put some temporary fence around the area that can be removed when the sandbags are removed. I would think that permanent could mean as permanent as the sandbags are.
