The sparks from a big TC are not really in the range of mA, however the 
waveform is chaotic and have peak current potentially in 10's of amps on a 
microsecond basis. Even my small TC will give muscular contraction so it 
must be haveing a physiological effect.
So the real safety answers?  Primaries are potentialy lethal and secondaries 
may be.
