Fractal wood burning remains a potentially lethal recreational activity

Fractal burning is a recent form of pyrography (decorative wood burning) using an extremely high voltage applied across a wood surface soaked in an electrolyte solution to produce a ferning or 'Lichtenberg' pattern. Two fatal cases of electrocution are reported in adults engaged in fractal burning to demonstrate characteristic features. Both had evidence of electrical contact with extensive burning. Death can occur following accidental contact with electrodes, the electrolyte solution or a loose wire, or when the victim stands on a conductive floor, or does not wear appropriate protective clothing, or has the wood on a non-insulated surface. Investigators need to check for these issues and to also determine whether the decedent had been appropriately trained in the handling of high voltage equipment.
