Jon,

Hmm ...  I think you might want to dig up your old first year electronics
texts ...
:-)

Please note that the spec is in Coulombs, not Farads (45 uC, not 45 uF).  
Capacitance (in Farads) is measured in Coulombs/Volt.

45uC at 14.9kV  = .335 Joules
45 uC at 100 V  = 0.00225 Joules

Energy hazards are usually a concern above 20 J, so a few mJ don't really
matter much.

>      And why 45uC?

Why not?
:-)

Happy New Year!
