Or, you come inside from the cold, pull off your hat and......BOING!!! Static electricity makes your hair stand on end
Slide 4:
The same phenomena which create lightning and thunderstorms are around us every day, creating incredibly high voltages which cause sparks and shocks.
Static electricity is most often experienced as nuisance shocks, but can in some circumstances cause explosions.
Static electricity is the imbalance of positive and negative charges. :
Static electricity is the imbalance of positive and negative charges. Everything we see is made up of tiny little parts called atoms.
Electrons have a negative (-) charge
Protons have a positive (+) charge
if you rub things together, electrons can move from one atom to another
When charges are separated, it is called static electricity.

Safe static electricity discharge (Grounding) :
Safe static electricity discharge (Grounding) preventing the occurrence of a flammable atmosphere.
preventing dangerous build-up of static charges by grounding metallic objects, and replacing insulating materials with static dissipative materials
