E54,
The C&G course is centred around the CoP rather than the mechanics of PAT.
You have to do it to teach it as well!
The need is that insurers & clients require it, because many of them know no better!!!
How about this.
New client, says I'll have to get you a hi-vis to go into the factory as our insurance co demands that all personnel wear one on site.
Me, do you have many vehicle movements in the factory then?
Client, no we have on FLT and it can't get everywhere, but, we still have to wear them everywhere.
Me, Oh!
When I look around, wiring does not meet regs, thus law, machines do not meet statute law, Ins Co. not interested, happy obviously to cover that risk, but they demand that loose fitting Hi-Vis is worn when working around rotating machinery...
