Question

question 16 of 16 a machine ______ is a device that is designed to keep the operator clear of dangerous machine parts. options: barrier, guard, rest, emergency stop. buttons: flag, reset, previous, next, go to overview

Explanation:

To solve this, we analyze each option:

• "Barrier" is more of a general obstruction, not specific to machine safety for operators.
• "Guard" in machine safety is a device designed to protect operators from dangerous machine parts by keeping them clear.
• "Rest" is for operator comfort, not safety from machine parts.
• "Emergency stop" is for halting the machine in an emergency, not for keeping the operator clear of parts.

So the correct option is "Guard".

Answer:

B. Guard
