Love your web site. Here is a guy working on a 3 phase sign, on a metal ladder that is tied to another ladder. If you look at the bottom of the picture a young lady is holding the ladder from sliding. Very Scary...
I am working on a business sign this week. Lazy as I am, I ask: wouldn't it be nice if signs were easily modified for maintenance? Signs like the one in the picture would benefit from having pegs extending that ladder hooks (as you use on lines) could "catch." No more ladder sliding. Signs that project from buildings over the sidewalk could easily be made so that the removal of a pin/bolt would allow you to swing the sign against the building. You could do your work either by leaning the ladder against the building, or while standing on the roof. It'd be nice, wouldn't it?
I've worked on tons of signs, generally from a boom truck but sometimes off a ladder. I'd put the ladder right on the face of the sign before I'd do that A frame trick . Why not lean the ladder on the side below the access hole the guy appears to be working in?. I actually think thats what happening and the other ladder is just laying there.
walrus, I don't actually think that the ladder is touching the sign is it?. It looks like there is a small gap between the head of the ladder and the sign surface, unless, my eyes are playing tricks on me!.
Now I see. It looks like one extenstion ladder leaning on the sign. You can see the locks part way down. There is a second extetion ladder leaning on the first one. Perhaps part of the job required a helper below handing stuff up. Still not safe on the lower ladder.
