Clive,
 
In the old days it was thought that the skin effect applied to TC's  and
that the discharges were safe.  Now it is realized that the skin  effect
does not apply.  Actually it does apply, but the skin effect for  human
flesh goes 17" deep so it offers no protection.  It that sense it  doesn't
apply in a practical sense.  Therefore the coil output should be  considered
very dangerous.  A person can touch the output of a small tube  coil for
example and feel nothing at all.  However the nerves and other  parts
of the body can be burning up inside.  The high frequency of the  current
is too fast for the nerves to react.  This makes things very  dangerous.
You don't receive any pain warning that you may be getting hurt by  the
RF currents.
