Rolling Ladder Incident
We recently had an incident where a rolling ladder was knocked off the tracks by a roof leg. The roof leg was pinned to low leg and the tank was filled to maximum level, causing the leg to make contact. This roof was installed in 2000 and taken out-of-service once in the past 25 years without addressing the design issue.
What would you do to prevent this from happening again, if taking the tank out-of-service is NOT an option at this time?
Please share any other thoughts you might have about putting it back, removing it from the roof for inspection, repairs, etc.
NOTE: not looking for help, just throwing the question out there as to how you would handle the situation internally. Currently we are not Operating the tank until we remove the ladder from service to perform further inspection and repairs or possible replacement.

Oof. Bad place to put a leg for sure…
Best thing to prevent recurrence is probably just to pull out the leg from the sleeve entirely (hoping it’s not a tabbed leg below preventing it from being pulled). This would make it not in the way and in theory you probably aren’t landing the roof intentionally without setting it to high leg and typically EFRs are fine landing with a single isolated leg missing/compromised/not touching, especially in the center deck.
