summary of Safety

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.
