Think of climbing onto youe roof, from a solar panel installation site.I think this sums it up, be careful.
Important disclaimer
It is possible to hurt your self. You can cut, burn, choke, poison, or scald yourself messing about with this. You could also fall from the roof or fall down the ladder with a cable around your neck on to a wooden stake. You could electrocute your self ( with power tools ). Blow lamps can explode and solder flux can give you dermatitis. You could get tetanus or blood poisoning from a splinter or paper cut. You could have an accident on the way to B&Q in the car. So if you follow these instructions its at your own risk. Wear goggles, steel toe cap boots, thick leather gloves, a face mask and hard hat at all times. Use an RCD and proper scaffolding . Never work outside in a thunder storm. Anything you do is your own fault, it’s not my fault. I am not your mum. Good Luck see you in the next life.
