HV wiring on sides of buildings that you could reach leaning outta the window.
Yepsome seriously scary things !
I remember one incident when a signage cotractor got lit at 24KV
. He is DOS (Dead On Scene)I guess, and my university went dark for ~30 minutes.(MEA had to clear the line then reset a CB in a substation.) they should have consult MEA before doing something near HV.
