Not comeing from anywhere Woody, all I think imo is if you use a ladder, and I used one at weekend 20 feet up cutting down conifers at my home, that they are secured, and you must agree 99% of trads dont secure them. I used a rojac stopper that cost £20 about 20 years ago, it still works great and at the time was recognised as a secure way by HSE for securing ladders, 15 years before WAHR. Tbhe trees where above a gonzolla roof, so platform would not be suitable.
Its simple, when we used to use ladders, we used a rojac stipper at bottom and a ladder limpit at top ,and felt 100% safe. Then WAHR came in, and as we work for large chemical industry on Teesside, where you are sacked if safety record is not just about perfect, we used WFP following WAHR.
We got a massive contract after another firm, twice made stupid mistakes regarding h & S and their contract was not renewed, and we benefited because of our zero accident record. its simple, keeps insurance down, keeps me from going to prison from corporate manslaughter, and no one gets seriously hurt. and I can sleep at night
