Which of the following actions can a technician take to reduce the chances of static charges being
built up? Each correct answer represents a complete solution. Choose three.
A.
Wear silken clothes.
B.
Do not wear wrist strap.
C.
Remove carpets from computer rooms.
D.
Wear cotton clothes.
E: Increase humidity level.
Explanation:
In order to reduce the chances of static charges being built up, users or technicians will have to take
the following steps:
Wear cotton clothes. This will reduce the chance of building up of static charges.
Do not cover the computer room’s floor with carpets. This stops neutralizing of static charges.
Increase humidity level. Humidity helps dissipate static charges.
What is ESD?ESD stands for Electrostatic discharge. The static electricity that we generate everyday creates ESD. If
you walk across a carpet and touch someone, you experience a mild shock. Electrostatic discharge
occurs when the electrostatic charge is transferred from one charged entity to another entity
sensitive to that charge.
To minimize Electrostatic discharge (ESD) problems, consider wearing a wrist strap when you are
working with computer components. A wrist strap is a wire with a watchband-style strap at one end
and a plug or clip on the other end. The wrist strap plug or clip is connected to the ground or to the
piece of equipment being worked on.
Answer option A is incorrect. A technician should not wear silken clothes during computer servicing,
as silken clothes are more likely to generate static charges than cotton clothes.
Answer option B is incorrect. Wearing wrist strap will keep a technician grounded. Hence, static
charges cannot build up.
