Let's keep in perspective that ratio of those who were killed divided by total users is way lower for bicycles than those who played dumb games with microwave transformer.

Only a few people die occasionally when climbing the worlds most dangerous mountain:

But we should focus on discouraging swimming and say anyone talking about the dangers of mountaineering is over-blowing the risk! lol, 30% vs 0.001% fatality rate.

Playing around with anything more than 100V, you'd better know what you are doing. No, a youtube demo is not enough training or information to do it safely. The only way to achieve competency in that sort of work is through one on one training and assessment as there are so many little things that need to be constantly thought about and considered. No magic bullet or simple checklist to be safe when working with exposed conductors for making Lichtenberg patterns in wood (hint, the patterns are from thermal burning, just as it will do to flesh).

Remember the below attached image is what ignorant consumers are sold! Low current, safe, warranty. Having been trained and worked on high voltage (and high fault current) live equipment, would I go near such a device? no way. Needs much more to make it safe enough for a trained person let alone an untrained idiot.

Ooof. Having the MOT plugged in the way he does raises a few concerns. You have to reach underneath the table in which the live MOT is sitting on, you could snag the cable and pull the whole thing off.

I would use an extension lead and physically pull the plug to turn it off. That way you turn it on or off while standing back from the unit. It's tedious, but you have a very obvious sign that the setup is de-energised before touching it.

No one would teach a Wood burning, Tesla coils and Jacob ladder training course ... too much liability, not enough profit.

Closest to training you can get is books and youtube videos from the tesla coil crowd.

Yeah, with this much power it's best to eliminate anything that can possibly go wrong. The rickety workbench in a dimly lit shed is a bad idea all around, I prefer to do that sort of ill advised ozone spewing stuff outside.
