Actually HSS do a PASMA tower course, about £100.

There is nothing at all wrong with using a tower, but they are so often assembled wrongly and not set up in place correctly.
I bet the people taking the course do all working at height training, so you may get info about working on ladders too.
You will learn safer, but also probably better and quicker ways to do jobs.
Im sure you would learn from the course, how to assess what each job you quote for needs in terms of equipment to work safely.
So u reckon these towers are much safer than ladders, maybe not as good as scaffold though?
I'll call them. Thxs for the link
