Such a needless tradgedy! Please leave fractal burning on the ash heap of things we should never do!
The process uses high-voltage electricity to create designs in wood and has gained popularity on social media sites.

Roger I agree 100 %. As a retired Industrial Arts teacher, I would never think of doing this at a school, club or at my home. It looks like the all volunteer team at SWAT2022 has a vendor who will be once again selling his "homemade neon sign Fractal Burner" in Waco.
It cannot be made safe. Not UL approved, Not UL tested. If you run it on top of your Saw Stop, it will leak enough current to throw the waste block into your blade. Extremely dangerous.
Would you trust your life to a free pair of $37 gloves to protect you from "
Output voltage 10,000-volt RMS. Output current 25± mA RMS."
Exposure to only 25 milliamps applied across your chest from right arm to left arm and you may not be able to let go.

The effects of electricity on the human body depend on many variables.
The strength of the current
Duration of contact
Body mass (small frames provide less resistance, large frames provide more)
Gender of the person
Moisture of the body
The path of the current
1 Milliampere | Perception level, a faint tingle |
5 Milliamperes | Slight shock felt, not painful, but disturbing
Average individual can let go
Strong involuntary reactions to shocks in this range can lead to injuries |
6-25 Milliamperes (women) | Painful shock
Muscular control is lost |
9-30 Milliamperes (men) | Freezing current or “let go” range |
50-150 Milliamperes | Extreme pain
Respiratory arrest
Severe muscular contractions*
Individual cannot let go
Death is possible |
1,000-4,300 Milliamperes | Ventricular fibrillation (the rhythmic pumping action of the heart ceases)
Muscular contraction and nerve damage
Death is most likely |
10,000+ Milliamperes | Cardiac arrest
Severe burns
Probable death |
*If the extensor muscles are excited by the electric shock, the person may be thrown away from the circuit.
