It may not be obvious due to paint, but that IS a fiberglass ladder.
Also, the ladder is not contacting any of the conduit; it passes over it. Good point to consider, though.
As for the "OSHA rule"... one of the very first issues OSHA had to litigate involved this very issue.
In the particulars of that case, the OSHA rule said trucks had to have their wheels chocked while in the loading dock. The defendant did not chock the wheels; he had anchors in the pit, and used a come-along to pull the truck tight against the dock.
OSHA argued 'a rule is a rule.' The defendant argued that his way was better.
The ruling, which was upheld on appeal, requires OSHA to recognise 'other approaches' that are as good, or better, than what the book specifies.
I believe that the 4-way ladder, used as pictured here, meets or exceeds any extension or tie-down requirement that was written with a different type of ladder (extension ladder) in mind.
This is, after all, America. We are NOT mindless serfs to a ruling bureaucracy.
