I hope you get well soon. It´s good that you had the kit when you needed it though it was not so good that needed it.
The prepapration failed on a earlier point. People know that there are intrisic dangers when you work on a ladder. Someone should hold the ladder to prevent tha fall in the first place. This is why accident prevention regulations say so. I kept my dad from a fall by insiting on this. After that he didn´t find it ridiculous any more.
