Settings

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.

7.

You walk over to a supply bin and find a sealed ESD package that your are looking for that has the following label: "Attention-State Sensitive Devices, Handle Only At Static Safe Workstations." What should you do?
- A.
  
  Don't pick up the ESD package as you might damage the item since you are not wearing an ESD control wrist strap
- 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

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
