Where is the emergency stop switch located?

• A. On the control panel
• B. In a remote location outside the lift
• C. Not accessible
• D. Located within reach, marked 'stop'

Answer: (D)

Emergency stop devices must be immediately accessible and clearly labeled so the operator can stop the machine quickly in an emergency. When the switch is within reach and marked "stop," it provides a fast, unambiguous way to shut down the escalator or moving walk without fumbling or delays. If the stop were only on a control panel that's hard to access, or placed in a remote location, stopping promptly could be delayed and unsafe. A clearly labeled stop button or switch that’s easy to reach ensures a rapid, definite action to halt the equipment. That's why the correct arrangement is a switch within reach and marked "stop."
