Assume circuits are on and check with voltmeter before handling __________.
- A.
The t.v remote
- B.
The computer
- C.
Wires
Correct Answer
C. WiresExplanation
Before handling wires, it is important to assume that circuits are on and check with a voltmeter. This is because wires carry electrical current, and if the circuits are on, there is a risk of electric shock or other electrical hazards. By using a voltmeter to check if there is any voltage present in the wires, one can ensure their safety before handling them.Rate this question:

Broken or damaged tools should be labeled with DAMAGED DO NOT USE. The instructor should be notified so that the tool may be repaired or replaced.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
The statement is true because broken or damaged tools should not be used as they can pose a safety risk. Labeling them with "DAMAGED DO NOT USE" ensures that others are aware of their condition and do not attempt to use them. Notifying the instructor is important so that they can take the necessary steps to repair or replace the tool, ensuring that it is safe to use again.Rate this question:

Which type of fire extinguisher should be used to put out an electrical fire?
- A.
Class A
- B.
Class B
- C.
Class C
- D.
Class D
Correct Answer
C. Class CExplanation
Class C fire extinguishers should be used to put out an electrical fire. This type of fire extinguisher is specifically designed to handle fires involving electrical equipment. It contains non-conductive extinguishing agents that can safely extinguish the fire without the risk of electric shock. Class C fire extinguishers are typically filled with dry chemical powder or carbon dioxide, which are effective in suppressing electrical fires by smothering the flames and cutting off the oxygen supply.Rate this question:

Which type of fire extinguisher(s) is or are also acceptable to put out an electrical fire?
- A.
Class C
- B.
Class B
Correct Answer
B. Class BExplanation
Class B fire extinguishers are also acceptable to put out an electrical fire. Class B fire extinguishers are designed to extinguish fires involving flammable liquids and gases. These extinguishers work by smothering the fire and cutting off its oxygen supply. Since electrical fires can be caused by short circuits or malfunctioning electrical equipment, they may involve flammable liquids or gases. Therefore, a Class B fire extinguisher can effectively extinguish an electrical fire by removing the fuel source and preventing the fire from spreading.Rate this question:

Which type of fire extinguisher will only make the fire worse?
- A.
Class A
- B.
Class B
- C.
Class C
- D.
Class D
- E.
Class E
Correct Answer
A. Class AExplanation
Class A fire extinguishers are designed to put out fires involving ordinary combustible materials such as wood, paper, and cloth. They use water or water-based solutions to cool the fire and extinguish it. However, using a Class A fire extinguisher on flammable liquids or electrical fires (Class B and Class C) can make the fire worse by spreading the flammable materials or conducting electricity. Therefore, using a Class A fire extinguisher on Class B or Class C fires is not recommended.Rate this question:

You should use safety glasses whenever around chemicals that may splash or objects that can be thrown.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Safety glasses should be used whenever around chemicals that may splash or objects that can be thrown to protect the eyes from potential harm. This is because chemicals can cause severe eye damage if they come into contact with the eyes, and objects that can be thrown may cause eye injuries if they hit the eyes. Therefore, it is important to wear safety glasses in these situations to ensure eye safety.Rate this question:

What is the maximum current level a human can withstand without getting injured?
- A.
1mA
- B.
15mA
- C.
100-300mA
- D.
6 A
- E.
None of these
Correct Answer
B. 15mAExplanation
The maximum current level a human can withstand without getting injured is 15mA. At this level, the current is low enough to prevent significant harm to the body. Higher levels of current can cause electric shock, muscle contractions, and even cardiac arrest. It is important to note that individual tolerances may vary, and factors such as the path of the current and the duration of exposure can also influence the level of injury.Rate this question:

Which of the following will burn your skin upon contact?
- A.
Shorted components
- B.
Soldering Irons
Correct Answer(s)
A. Shorted components
B. Soldering IronsExplanation
Both shorted components and soldering irons have the potential to burn your skin upon contact. Shorted components can generate heat due to excessive current flow, which can cause burns if touched. Soldering irons, on the other hand, are heated tools used for soldering electronic components, and if touched accidentally, can cause severe burns due to their high temperature. Therefore, both shorted components and soldering irons can be hazardous and cause burns to the skin upon contact.Rate this question:

Smoke from burning or metal components
- B.
Battery chemicals
- C.
Older, lead based solder
- D.
Printed Circuit board etching materials
- E.
All of the above
Correct Answer
E. All of the aboveExplanation
All of the options listed in the question can cause injuries. Smoke from burning or metal components can release toxic fumes that can be harmful if inhaled. Battery chemicals can be corrosive and cause burns or skin irritation. Older, lead-based solder can release lead fumes which can be toxic if inhaled or ingested. Printed circuit board etching materials can also contain harmful chemicals that can cause injuries if not handled properly. Therefore, all of the options mentioned can potentially cause injuries.Rate this question:

Small wires can easily puncture the skin.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Small wires can easily puncture the skin because they are sharp and have a small diameter. The sharpness allows them to pierce through the outer layer of the skin, while the small diameter ensures that they can penetrate without causing too much damage. Additionally, the force required to puncture the skin is lower for small wires compared to larger objects. Therefore, it is true that small wires can easily puncture the skin.Rate this question:

Pulling out Integrated Circuits incorrectly will not cause harm.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Pulling out Integrated Circuits incorrectly can cause harm. Integrated circuits are delicate electronic components that are sensitive to electrostatic discharge (ESD) and physical damage. Mishandling or pulling them out incorrectly can lead to damage to the circuitry or the pins, rendering the IC useless. It is important to follow proper procedures, such as using ESD protection measures and gently removing ICs, to prevent any harm or damage.Rate this question:
