[6] While it was not the most successful at conveying to children the hazard was electrical, it was the most successful at conveying the presence of a hazard and encouraging avoidance. Pictogram Q, with the wire with a plug shocking the hand ...
Shock danger may be reduced by use of an extra-low voltage electrical system that is unlikely to expose a human to dangerous levels of current. Special isolated power systems may be used in applications such as operating rooms, where electrical equipment must be used in proximity to a person unusually vulnerable to electrical shock.
On roadside warning signs, an exclamation mark is often used to draw attention to a generic warning of danger, hazards, and the unexpected. In Europe and elsewhere in the world (except North America and Australia), this type of sign is used if there are no more-specific signs to denote a particular hazard.

Three elements are required for an electrocution to occur: (a) a charged electrical source, (b) a current pathway through the victim, (c) a ground. The health hazard of an electric current flowing through the body depends on the amount of current and the length of time for which it flows, not merely on the voltage. However, a high voltage is ...
