Problem:

Hospital operating theatres, floors are made out of conducting material and staff wear shoes made of conducting material not insulating material.

How is charge built up on insulating soles and how does using conducting material reduce charge & sparks?

Answer so far:

No free movement of electrons in insulating materials therefore the charge is built up over time, by using conducting materials the electrons are free to move from one place to another therefore not building up charge.

As for this question, I didn't know about it before. So it is an interesting info. But i was wondering, wouldn't the risks of getting electrocuted increase by having conducting materials under your feet?
