An automotive ignition system can be the source of electric injury.
Risk factor for electrical injury:
(1) person working on the ignition system (car service employee, home mechanic)
(2) ignition system capable of generating a high voltage
(3) improper grounding
People at increased risk if exposed to an electrical discharge:
(1) pacemaker
(2) pro-arrhythmic heart disease
A person exposed to an electric shock may also act by reflex, which can result in injury if something is struck while moving away.
