Questions and Answers

1.

Safety-related work practices involve:
- A.
  
  The use of ground fault circuit interrupters
- B.
  
  Verifying power is off before doing repairs
- C.
  
  Keeping proper distance from overhead power lines
- D.
  
  All of the above
Correct Answer
D. All of the above

Explanation
Safety-related work practices involve the use of ground fault circuit interrupters to protect against electrical hazards. Verifying power is off before doing repairs ensures that workers are not exposed to live electrical currents. Keeping a proper distance from overhead power lines reduces the risk of electrocution. Therefore, all of the given options are correct and are part of safety-related work practices.

2.

The following is an example of work that may be performed by a person who is not an electrician:
- A.
  
  Construction of an extension cord using a standard junction box
- B.
  
  Removal of grounding pin from appliance cord plug
- C.
  
  Use of proper extension cord to power an appliance for a short time
- D.
  
  None of the above
Correct Answer
C. Use of proper extension cord to power an appliance for a short time

Explanation
The correct answer is "Use of proper extension cord to power an appliance for a short time." This answer is correct because using a proper extension cord to power an appliance for a short time does not require specialized electrical knowledge or skills. It is a task that can be safely performed by someone who is not an electrician. The other options listed involve potentially dangerous actions that should only be performed by a qualified electrician.

3.

Electrical current can flow through concrete
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Concrete is a composite material made up of cement, water, and aggregates. While it is not a good conductor of electricity, it does have some conductivity due to the presence of water and impurities in the concrete. This means that electrical current can flow through concrete, although it may be at a slower rate compared to other conductive materials. Therefore, the statement "Electrical current can flow through concrete" is true.

Rate this question:
4.

Which of the following are classified as unsafe acts:
- A.
  
  Altering a 3-prong plug to fit a 2-prong outlet
- B.
  
  Using a GFCI
- C.
  
  Working too close to overhead power lines
- D.
  
  A and C
- E.
  
  All of the above
Correct Answer
D. A and C

Explanation
The correct answer is "A and C". This means that both altering a 3-prong plug to fit a 2-prong outlet and working too close to overhead power lines are classified as unsafe acts. Altering a plug can result in electrical hazards and potential shock or fire risks. Working too close to overhead power lines can lead to electrocution or electrical accidents. Using a GFCI (Ground Fault Circuit Interrupter) is not classified as an unsafe act as it is a safety device designed to protect against electrical shocks.

5.

Electric cords connected to equipment may be used for raising or lowering the equipment.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Electric cords are not designed or intended for raising or lowering equipment. They are primarily used for providing electrical power to the equipment. Raising or lowering equipment typically requires the use of specialized mechanisms such as pulleys, cranes, or hydraulic systems. Therefore, the statement that electric cords connected to equipment may be used for raising or lowering the equipment is false.

Rate this question:
6.

Conductive articles of jewelry and clothing may be worn around exposed energized parts.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Conductive articles of jewelry and clothing should not be worn around exposed energized parts because they can create a pathway for electrical current to flow through the body, resulting in electric shock or injury. It is important to avoid wearing conductive materials in situations where there is a risk of coming into contact with energized parts to ensure personal safety.

Extension cords must have the following:
- A.
  
  UL Listing
- B.
  
  Three prongs
- C.
  
  A fuse
- D.
  
  A and B
- E.
  
  All of the above
Correct Answer
D. A and B

Explanation
Extension cords must have UL Listing and three prongs. UL Listing ensures that the extension cord has been tested and certified for safety by Underwriters Laboratories. Three prongs indicate that the cord is grounded, providing an extra level of safety. A fuse is not a requirement for extension cords, so the correct answer is A and B.

University departments may decide whether to have alterations done by Physical Plant personnel or to do it themselves.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
University departments may decide whether to have alterations done by Physical Plant personnel or to do it themselves. This statement is false because the decision of whether to have alterations done by Physical Plant personnel or to do it themselves is typically made by the university administration or facilities management, not individual departments.

Rate this question:
9.

Non-conductive head protection should be worn whenever there is a danger of head injury from electric shock.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
Non-conductive head protection is necessary to prevent electric shock-related head injuries. This is because non-conductive materials, such as plastic or rubber, do not conduct electricity and can help to insulate the head from electric shocks. Wearing non-conductive head protection reduces the risk of electrical currents passing through the head and causing serious injury or electrocution. Therefore, it is important to wear non-conductive head protection in situations where there is a potential danger of head injury from electric shock.

Rate this question:
10.

Reaction to static electric shock may cause injury.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
When a person experiences a static electric shock, it can potentially cause injury. This is because the shock can disrupt the normal functioning of the body, leading to various harmful effects. The severity of the injury depends on factors such as the intensity of the shock, the duration of exposure, and the individual's overall health. In some cases, static electric shocks can result in burns, muscle contractions, nerve damage, and even cardiac arrest. Therefore, it is important to be cautious and take necessary precautions to avoid static electric shocks and minimize the risk of injury.
