------------------------------------------------ Which of the following tool components is unlikely to present a hazard?

A. Abrasive wheel
B. Constant-pressure switch
C. Chainsaw blade
D. Sanding belt

Answer :

Final answer:

The tool component least likely to present a hazard is the constant-pressure switch because it requires continuous force to operate, enhancing safety. In contrast, components like abrasive wheels, chainsaw blades, and sanding belts can pose significant risks. Thus, the constant-pressure switch minimizes hazards effectively.


Explanation:

Understanding Tool Hazards


When evaluating which tool component carries a hazard, we must consider how each component operates during use.



  1. Abrasive wheel: This tool can create sparks and release material particles, posing a risk of injury.

  2. Constant-pressure switch: This component generally ensures safety by requiring a continuous force to be applied for activation, making it relatively safer compared to the other options.

  3. Chainsaw blade: This is highly dangerous due to its sharp teeth and high-speed rotation, risking severe injuries.

  4. Sanding belt: This can also be hazardous as it can cause abrasions and possible entanglement if not used correctly.


Among these options, the constant-pressure switch is the one least likely to present a hazard because it is designed to enhance safety by preventing accidental activation.
