Question

a(n) ______ is a device or system that shuts down a machine immediately if the operator is in danger.
○ emergency stop
○ cycle stop
○ halt
○ pause
flag reset
previous next

Explanation:

To solve this, we analyze each option:

• "Emergency stop" is a device/system designed to immediately shut down a machine in dangerous situations for the operator.
• "Cycle stop" typically stops a machine at the end of a cycle, not for immediate danger.
• "Halt" is a general term and not specific to immediate danger - related machine shutdown for operator safety.
• "PAUSE" is a temporary stop, not for immediate danger response.

So the correct option is "Emergency stop".

Answer:

A. Emergency stop
