I have been involved with the training and design,of both courses and equipment,in this industry.
You can instruct operatives on each part of the operation,inspections,assessment etc,but it only becomes successful training if they consider ALL the parts of that instruction.
Most of the bad accidents i have had the sad duty of investigating,have occurred due to the operator failing to notice what is happening at the top,when operating the ground controls,or,failing to notice what is happening on the ground,when operating from the extended platform.
Occasionally,a fellow who might work in construction,sustains an electric shock,from an overhead power line,whilst waving their carbon-fibre roach pole about...
It's a dangerous world :bobby:
