summary
● Voltage is the pressure behind electrical current, which can result in electrical shock.
● The higher the body resistance, the less current will flow through it.
● When dealing with someone who is experiencing severe electrical shock, send for help; locate and remove the source of power.
● Do not work on any circuit or equipment unless the power is secured.
● Insulating and grounding are two techniques for preventing electrical shock when working with electrical tools and equipment.
● A GFCI is a fast acting circuit breaker that is sensitive to very low levels of current leakage to ground.
● An Underwriters Laboratories label and a Canadian Standards Association label on a product indicate that it is safe to use as intended without any response to its quality.
● When a charged substance discharges through a conductor, an electric current flows to ground potential and is referred to as electrostatic dis- charge (ESD).
● A person can feel a shock from an electrostatic discharge of 3500 to 4000 volts.
● An ESD latent discharge results in a device work- ing properly but failing later.
● An electronics technician should be grounded to discharge static electricity buildup on the body before working on a sensitive electronic circuit.
● Components on printed circuit boards can be damaged by static electricity, referred to as electrostatic discharge (ESD).
● Antistatic workstations are designed to provide a ground path for static charges that could damage a component.
