It is okay to put a portable grinder in a vise as long as it is tightened securely.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Putting a portable grinder in a vise is not safe, even if it is tightened securely. Portable grinders are designed to be handheld and operated without being clamped down. Placing a grinder in a vise can cause it to vibrate excessively, potentially leading to damage or injury. It is recommended to use the grinder as intended, holding it securely with both hands while in use.

Most hazards associated with hand tools are easy to spot because we very seldom would use a tool in "day-to-day" life.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
The statement is false because hazards associated with hand tools are not always easy to spot. While some hazards may be obvious, there are also many hidden hazards that may not be immediately apparent. It is important to be aware of potential hazards and take necessary precautions while using hand tools to ensure safety.

Guards should offer protection from..?
- A.
  
  Point of Operation
- B.
  
  In-running Nip Points
- C.
  
  Spilled Liquids
- D.
  
  Rotating Parts
- E.
  
  Open Toed Shoes
- F.
  
  Flying Chips or Sparks
- G.
  
  Loose Clothing Gettin in the way
Correct Answer(s)
A. Point of Operation
B. In-running Nip Points
D. Rotating Parts
F. Flying Chips or Sparks

Explanation
Guards should offer protection from various hazards in the workplace, including the point of operation, in-running nip points, rotating parts, and flying chips or sparks. The point of operation refers to the area where the work is actually performed on a machine, and guards are necessary to prevent contact with moving parts that could cause injury. In-running nip points are areas where rotating parts come into contact with each other, and guards are needed to prevent fingers or clothing from getting caught. Rotating parts, such as gears or belts, can also pose a danger if not properly guarded. Finally, guards are necessary to protect against flying chips or sparks that could cause eye injuries or ignite flammable materials.

Tools requiring momentary on/off switches can never have a lock-on switch.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Tools requiring momentary on/off switches can never have a lock-on switch. This statement is false. Some tools, such as power drills, have momentary on/off switches for safety reasons, but also have a lock-on switch to allow continuous operation without holding down the button. The lock-on switch is useful for tasks that require prolonged use of the tool, reducing hand fatigue. Therefore, it is possible for tools with momentary on/off switches to also have a lock-on switch.

Never use electric tools in what kind of condition/conditions?
- A.
  
  Humid
- B.
  
  Cold
- C.
  
  Wet
- D.
  
  Snowy
Correct Answer
C. Wet

Explanation
Electric tools should never be used in wet conditions because water is a conductor of electricity. This can lead to electric shock or short circuiting, posing a significant risk to the user. It is important to ensure that the working area is dry and free from any moisture before using electric tools to ensure safety.

You should always wear eye protection when using grinders.
- A.
  
  True
- B.
  
  False
Correct Answer
A. True

Explanation
It is important to wear eye protection when using grinders because they can produce sparks, debris, or fragments that can potentially cause eye injuries. Eye protection, such as safety glasses or goggles, helps to shield the eyes from these hazards and minimize the risk of accidents or damage to the eyes. Therefore, it is recommended to always wear eye protection when using grinders to ensure safety.

Which of the following parts should be guarded on tools?
- A.
  
  Belts
- B.
  
  Off Switch
- C.
  
  Gears
- D.
  
  Shafts
- E.
  
  Electical Outlet
- F.
  
  Pulleys
- G.
  
  Sprockets
- H.
  
  Independant Spindles
- I.
  
  Spindles
- J.
  
  Drums
Correct Answer(s)
A. Belts
C. Gears
D. Shafts
F. Pulleys
G. Sprockets
I. Spindles
J. Drums

Explanation
Tools should have guards on parts that pose a potential hazard to the user. Belts, gears, shafts, pulleys, sprockets, spindles, and drums are all moving parts that can cause injury if they come into contact with a person's body or clothing. Guards help to prevent accidental contact and reduce the risk of injury. The off switch and electrical outlet are not parts that need to be guarded, as they do not pose a direct physical hazard.

Because powder-actuated tools use small explosive charges, it is okay to use them in explosive atmospheres.
- A.
  
  True
- B.
  
  False
Correct Answer
B. False

Explanation
Powder-actuated tools use small explosive charges to drive fasteners into materials. These tools should never be used in explosive atmospheres because the sparks or heat generated from the tool's operation can ignite the explosive atmosphere, causing a potentially dangerous situation. Therefore, the statement is false.

When not in use, power tools should be..?
- A.
  
  Played with
- B.
  
  Disconnected
- C.
  
  Physically Abused
- D.
  
  Put up in a pile of other tools
Correct Answer
B. Disconnected

Explanation
When not in use, power tools should be disconnected. This is important for safety reasons as it prevents accidental activation of the tool and reduces the risk of injury. Disconnecting the power source also helps to preserve the life of the tool by preventing unnecessary wear and tear. Additionally, it is good practice to disconnect power tools to conserve energy and prevent any potential electrical hazards.
