In my first or second year, I set a ladder at a 45 degree angle on a lawn! Really clever, I was working at about 2 meters up and after a few seconds of getting up to the window, it slipped away. All I can tell you is, you don't get time to do anything at low level work, as the ladder hit the ground, I was still on it. I bent the rung I was stood on with the impact. No broken bones, just bad bruising on the soles of my feet. Couldn't walk at all for 2 days, and it was 2 weeks before I could work again.
Since then, I am alot more carefull and always look at how my ladders stand, if I'm not sure, I get mrs Cozy to foot it. I never use a ladder without a stabilizer and as far as I'm concerned, don't take any risks. I was abit gung ho when I first started, but you live and learn.
Once you have had an accident with ladders, you tend to learn or start picking your menu from a hospital porter at best.
