Fiberglass is reinforced plastic, though, so that might explain why it isn't used in FDs even if it's heavily used in other domains. How well does it hold up to heat? How does that exposure effect it structural properties? I honestly don't know and don't have time to look it up, but I could see thermal plastic deformation over such a long run as potentially hazardous.

Could be. I know film shoots can end up occurring in all kinds of weather (especially here in Canada), and often the ladders will be sidled up to large sun lamps (which I can assure you get very hot), and in electrically-compromising situations, but all of those are very different from an actual fire.

Wow. I wish I had time in the day to look at NFPA (Nat'l FIre Protection Assn) standards. 1931, 1914, and 1911 seem pertinent - this is clearly something that many people have devoted a lot of time and energy to.
