Walls or Garages whatever is in the way. I didnt think i would be invoking such a lengthy debate - Peace
Walls and gates are more suitable for ladder use (due to their generally being six foot high or less your feet don't have to be more than about four feet off the ground. Garages are definitely not IME. (As you've probably guessed!
)
I'll never apologise for banging the drum against unnecessary ladder use, Steve - over my years in this business I've known of w/c's die, become brain-damaged, never walk again or simply lose months off of work due to a fall. I personally climbed ladders about 100 times a day, often to first floor and occasionally to second floor. Never fell but had a few near misses. Now I use a short ladder for only for gates and sometimes for high groundfloor window cleaning work.
Just because previous generations smoked forty a day without a care in the world or sprayed cars without PPE or simply drove without seatbelts doesn't mean that you or I need to.
You just talk to your customers about the issues and you come to an accommodation with them - if they want you to risk your neck just because some "numpty" will if you don't - well who wants custy's like that?
If you become skilled at wfp you will reach far more previously innaccessible windows and rooflights than you could hope to get to using ladders. You can do backs of terraces quite easily - I've got quite a few. You just have to be imaginative and you will offer a really good service to your custy's.
