(218) Which type of machine guard is preferable to all others?
-
Fixed.
-
Interlock.
-
Adjustable.
-
Self-adjusting.
Correct Answer
A. Fixed.Explanation
Fixed machine guards are preferable to all others because they provide a permanent physical barrier that cannot be easily bypassed or tampered with. Unlike adjustable or self-adjusting guards, fixed guards cannot be altered or moved, ensuring consistent protection for operators and preventing unauthorized access to hazardous areas. Interlock guards may be effective in certain situations, but they rely on the proper functioning of interlocking mechanisms, which can be prone to failure. Overall, fixed guards offer the highest level of safety and reliability in machine guarding.Rate this question:

(202) When a procedure or piece of equipment exceeds the limits of safe noise exposure, what is the best course of action?
-
Isolate the procedure or equipment from personnel.
-
Require personnel to wear earmuffs or earplugs.
-
Warn personnel about the noise hazard.
-
Conduct a sound-level survey.
Correct Answer
A. Isolate the procedure or equipment from personnel.Explanation
The best course of action when a procedure or piece of equipment exceeds the limits of safe noise exposure is to isolate the procedure or equipment from personnel. This means physically separating the procedure or equipment from the workers to minimize their exposure to the excessive noise. By doing so, the risk of hearing damage or other health issues related to noise exposure can be reduced. This solution is more effective than simply requiring personnel to wear earmuffs or earplugs, warning personnel about the noise hazard, or conducting a sound-level survey.Rate this question:

(214) When using files, what action frequently leads to puncture wounds?
-
Failure to use gloves.
-
Improper maintenance.
