Reddit reviews Little Giant 14013-001 Model 17 250 Lbs Capacity Alta-One Ladder, 15 Feet

Field damage appraiser/adjuster since 1994 here:

1. On site on a property claim you'd be taking photos, taking measurements with a tape measure, asking questions about how the damage happened and any steps taken to mitigate further damage after the event. I use one of those brown clipboards but a lot of adjusters "storage clipboards" like this, except usually plastic instead of metal. Property adjusters usually have a car large enough to hold a folding ladder.
   
   Back in the 90's my carrier had me wearing a suit & tie, even climbing on roofs and such. We even wore leather-soled shoes on asphalt roofs and slip-on covers like Cougar Paws to keep from sliding off roofs. Nowadays we wear khaki pants, a light jacket, and light hiking boots/shoes.
   
   
2. A "Multi-line" adjuster is somebody who looks at claims from multiple lines of business, like property, auto, and casualty/injury claims. A "general adjuster" is actually a specific type of property adjuster with a high level of authority. This position is defunct at a lot of companies now but in the 90's it would usually be a property adjuster with 20-30 years of experience who handled really big commercial/homeowner losses. Like stuff so big they may get fewer claims in an average month than you could count on one hand. Most companies have their field claims staff split-up by line of business but a few still have multi-line reps. it is conceivable that one would be assigned a slip & fall at the same time as handling a hurricane damage claim. If I was creating a character for this they'd not be a CAT team member but perhaps the usual local guy who did regular multi-line claims and was helping out the cat team while they were in his area.
   
   
3. In the 90's it would normally take a couple weeks before you'd go look at a claim like somebody being injured by a door. it would take that long to filter through the system. Even for a serious car accident it might be a few days. i was a field casualty adjuster in the 90's and even very serious car and home accidents didn't reach my in-box for at least several days. Sometimes it was months.

Safest is to get some scaffolding, and set it up in the stairwell with 'long legs' on the low end and 'short legs' at the top of the stairs. Next option is this kind of ladder system if you can get one. (it's a good thing to have around..)

And then, of course, you have the roller-on-a-stick option, which I personally hate due to the mess, the difficulty of maintaining correct pressure on the end of a pole, and trying to stay steady on steps while your eyes are focused on the ceiling.
