Reminds me of a guy, on a 10ft alum. ladder right next to the spa I was relaxing in, vaccuming ceiling tiles.

I got out of the spa and asked if the recept he was using was GFCI protected, and he said HUNH??. I found the recept was not protected and unpluged the cord. He threw a fit and called his manager, who also blew me off.

I got dressed and called the AHJ, and the fire dept, who arrived a little later, cited them and explained why.
