Depends on the power levels and size of secondary top
loads in general.
Powerful coils in KW+ range ,with a big hats, can
knock you down with no problem.Especially if you are
grounded.
Please note that coilers prefer design with big
toroids today.
Smaller, 100 W coils with small or no toroids, usually
deliver just a slight shock or no shock at all.But
this can also vary.
As concerns burns,they can occur always:depending on
the duration of current flow,contact areas etc.
Primary tank directly linked to PSU ,is a very
dangerous system part.Can be a killer for humans,even
in less powerful coil.
VTTC and CW operated coils ,due to different
excitation modes,produce smother rf output with
decreased or no DC component.Electric shock is not
hazard,but burns can be very nasty.
My advice :avoid contact with sparks.

I hesitated to say this but I couldn't resist a
temptetion. In my eyes they look like a complete
idiots doing that (and releasing such pics on the
internet)
Safe coiling,
Boris
