Does anyone have any actual data points for injuries from tesla coils? There is little if anything about it on the internet. There are lots of people who play around near them in suits etc, but I can't find a single report of "Yeah, that burned" or similar.

I can attest that RF burns hurt.
Streamers arcing to a metal object held in your hand don't really hurt unless interrupted, which would indicate it's a bad idea. Mind you all of this is at low power (150W) But that's just my 2 cents.
You can touch the supply ground of a battery powered slayer exciter and a ground plane will burn every time like a hot plate though the metal is at room temperature. That’s one of the few parts you can touch that may not stop it oscillating like touching the toroid would.

So are you saying if you touch the toroid of a working tesla coil it will effectively alter its capacitance and stop oscillation in turn killing its power output?
A slayer exciter is the same transformer hardware (usually smaller), with a single transistor driver of low power that relies on feedback from the secondary for the driver to oscillate at all.
For your typical Tesla coil, if the driver was driven with with the extra coil to provide feedback as in many valve circuits maybe, but I don’t think there is ever a time the toroid is fully discharged to make that safe.

If you're going to play with fluorescent tubes, don't just hold them up to an arc. I did that a few times with my SGTC and it hurts!
Always ground the bottom end of your tubes. When the gas strikes inside it becomes a better conductor then you! Grounding the tube makes it safe for you, kids, and other spectators.

Yes that would be a wise move, i will be interested to see how it will work when i get mine going.

Interesting. I was looking for some documentation around persistent damage o injury caused by these devices. I realize that people are injured/die from 120/220 mains frequently, and the primary on the coils i have worked with are moving something like 2kA, which is obviously dangerous.
I guess I was mainly curious if people have been injured by sparks/streamers from secondaries. I don't ask this question lightly, and I am aware of the notional dangers, but I am really presently looking for some tangible/documented events.
