Correct Answer
B. Prior to first use daily (Only on days of actual use)
Explanation
Single conductor (non-constant monitored) ESD control wrist straps should be tested prior to first use daily (Only on days of actual use). This means that the wrist strap should be checked for functionality and proper grounding before it is used each day. This ensures that the wrist strap is working effectively to prevent electrostatic discharge (ESD) and protect sensitive electronic components. Testing the wrist strap on days of actual use ensures that it is in good working condition when it is needed.
5.
ESD Sensitive (ESDS) items are susceptible to ESD damage until such time that they are properly packaged in ESD control electrostatic shielding packing materials.
Correct Answer
A. True
Explanation
ESD sensitive items are vulnerable to ESD damage unless they are appropriately packaged in electrostatic shielding packing materials designed for ESD control. This means that without proper packaging, these items can be easily damaged by electrostatic discharge. Therefore, the statement "ESD Sensitive (ESDS) items are susceptible to ESD damage until such time that they are properly packaged in ESD control electrostatic shielding packing materials" is true.
6.
You are working at an ESD control workstation and have some job essential tools with electrically conductive tips and insulative handles. What would be the best approach before using these tools on ESD sensitive items?
Correct Answer
D. Either a or c
Explanation
Before using the job essential tools with electrically conductive tips and insulative handles on ESD sensitive items, the best approach would be to either touch the tip of the tool to the ESD work surface or touch the tip of the tool with your fingertip to dissipate any static charges through your grounded wrist strap. Both options help to prevent any static charges from damaging the ESD sensitive items.
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?
Correct Answer
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
8.
An ESD control workstation work surface may be used for :
Correct Answer
D. Both A and B
Explanation
An ESD control workstation work surface may be used for work that requires handling of ESD Sensitive items and work other than ESD control work provided that no ESD sensitive items remain unprotected at the workstation during this time. This means that the work surface can be used for tasks involving ESD sensitive items as well as non-ESD control work, as long as the ESD sensitive items are properly protected or removed from the workstation during non-ESD control work.
9.
Standard single conductor wrist straps (without constant monitoring) require:
Correct Answer
D. Both A and C
Explanation
Standard single conductor wrist straps without constant monitoring require both a daily test log and a wrist strap tester. A daily test log is necessary to document the regular testing of the wrist straps to ensure they are functioning properly. Additionally, a wrist strap tester is needed to periodically test the resistance of the strap to ensure it is within acceptable limits. Both of these measures are important to maintain the effectiveness of the wrist straps in dissipating static charges and protecting sensitive electronic equipment.
10.
Static generating materials may be present at the ESD control workstation with ESD sensitive items if:
Correct Answer
A. The static generating materials are job essential
Explanation
Static generating materials may be present at the ESD control workstation with ESD sensitive items if they are job essential. This means that if the materials are necessary for the completion of the job or task at hand, they can be allowed in the workstation despite their potential to generate static electricity. However, it is important to ensure that proper ESD control measures are in place to minimize the risk of damage to the sensitive items.
11.
A signed ESD control certification document should be :
Correct Answer
D. Either A or B
Explanation
A signed ESD control certification document should be either posted at the entrance to the ESD work area or stored in a readily accessible file. This ensures that the document is easily visible and accessible to anyone entering the area, allowing them to verify that proper ESD control measures are being followed. Hanging the document on the refrigerator is not a suitable option as it may not be easily visible or accessible to everyone who needs to see it.
12.
The entrance to an ESD control work area shall have an attention sign alerting personnel that they are entering an ESD protective area.
Correct Answer
A. True
Explanation
The entrance to an ESD control work area should have an attention sign to alert personnel that they are entering an ESD protective area. This is important because ESD (electrostatic discharge) can cause damage to sensitive electronic components. By having a sign, personnel are reminded to take necessary precautions to prevent ESD, such as wearing appropriate grounding devices and handling equipment properly. This helps to maintain a safe and controlled environment for handling electronic devices and prevents potential damage.
