1
1.2) What is ESD? - ✔✔ESD(electrostatic discharge) is a situation that occurs when
electrons rush from one statically charged body to another with an unequal charge
following the path of least resistance.
1.2) ESD - ✔✔High voltage but low current caused by excessive static electricity. its
less dangerous to humans than electronics people feel ESD at 2500v equipment can be
damaged by as little as 100v
1.2) ESD generators - ✔✔synthetic clothing
low humidity
cooler temperatures
1.2) What is self grounding? - ✔✔the act of touching a grounded object before
touching electronic equipment.
1.2) examples of self grounding - ✔✔ESD wrist or leg strap
(use ground clip and attach to ground point)
Using antistatic bags
Using ground points
ESD protective work surface
, ESD protective mats
1.2) protecting components from ESD - ✔✔drain body from static electricity
work in an uncarpeted area
if no ESD removers you can simply hold the case of the PC (unpainted metal part) to
remove your ESD
handle vulnerable components by there edges and avoid touching the surfaces of chips
themselves.
.2) Types of regulations - ✔✔Health and safety laws
Building codes
Environmental regulations
1.2.) OSHA prime example for safety regulations for US based operations -
✔✔workplace free from recognized hazards.
personal protective equipment.
communication (labels MSDSs hazmat training)
1.2}Employers and employees both have responsibilities. - ✔✔Employers provide a
safe workplace
Employee actions promote safety of themselves and others
1.2) What is a Ground? - ✔✔A safe path for the electrical current to flow away in the
event that a device or cable is faulty.
1.2) Most PC circuits are low voltage/ low current what are some notable exceptions. -
✔✔power supplies.
