Do You Know About ESD? Electric Quiz
Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects cause by contact an electrical short, or dielectric breakdown. ESD occurs when two electrically charged objects contact each other, are involved in an electrical short or suffer a dielectric breakdown, resulting in a sudden flow of electricity.

- B.
Pick up the ESD package and take it to an ESD workstation, then put on an ESD control wrist strap before you open the package
- C.
Since the item is already packaged in ESD Packaging, it is safe to open the package even though you're not wearing an ESD Control Wrist Strap
- D.
Open the ESD package to verify the contents, then take the package over to an ESD work station for proper handling
- 8.An ESD control workstation work surface may be used for :
- A.
Work that requires handling of ESD Sensitive items
- B.
Work other than ESD control work provided that no ESD sensitive items remain unprotected at the workstation during this time
- C.
Anything including eating your lunch or making coffee
- D.
Both A and B

- A.
A daily test log
- B.
No testing
- C.
A wrist strap tester
- D.
Both A and C

The static generating materials are job essential
- B.
Static generating materials are never allowed on the work surface
- C.
The static generating materials have been recently cleaned
- D.
None of the above
- 11.A signed ESD control certification document should be :

Posted at the entrance to the ESD work area
- B.
Stored in a readily accessible file
- C.
Hung on the refrigerator

Either A or B
- 12.The entrance to an ESD control work area shall have an attention sign alerting personnel that they are entering an ESD protective area.
- A.
True
- B.
False
- 13.Which of the following best describes how an ESD sensitive item (e.g. circuit board) should be handled if you need to remove it from the ESD workstation and you will no longer be wearing your ESD control wrist strap and you do not have an ESD flooring system?
- A.
Place the item in a "pink poly" bag before removing from the ESD workstation
- B.
For temporary transit and storage, no ESD precautions are necessary. For long term strage, ensure that is is properly packaged in an ESD shielding bag or placed in an ESD tote box with lid before removing from the ESD workstation.
- C.
Place the item in a "clear poly" bag before removing from the ESD workstation
- D.
Ensure that it is properly packaged in an ESD shielding bag or placed in an ESD tote box with lid before removing from the ESD control workstation
- 14.You need to perform maintenance on a console that contains ESD sensitive items. The maintenance action requires you to ensure that power is off and then remove a cover/panel that will expose the sensitive electronics. What should you do?
- A.
You disconnect powe and put on your ESD control wrist strap which you've bonded to the item's chassis, remove the cover and proceed with the maintenance action.
- B.
You disconnect power. Since you do not intend to remove any ESD sensitive items from the console, no additional ESD precautions are necessary.
- C.
Lock the entrance to the work center so that no one can enter the work area. Open the panel and quickly perform your maintenance action.
- D.
Lock the entrance to the work are so that no one can enter. Put on a wool sweater, rubber boots, and gloves. Disconnect the power and open the panel while scooting your feet repeatedly on a carpeted surface. Quickly perform your maintenance action. Touch someone afterwards to discharge any built up static charge
