If a scaffold motor gets stuck in the up position, what should you do?

• A. Hit the emergency stop and unplug the unit
• B. Restart the motor
• C. Lower the platform manually
• D. Call supervisor

Answer: (A)

When a scaffold motor gets stuck in the up position, the priority is to stop any movement and remove electrical energy to prevent a sudden rise or drop that could injure someone or cause a fall. Hitting the emergency stop immediately halts all motion and cuts power to the drive system, reducing the risk of the platform continuing to move. Unplugging the unit further isolates power to the motor and control circuits, making it less likely the system will re-energize unexpectedly while you’re assessing or waiting for qualified help. Restarting the motor would reinitiate motion and could trap or injure someone, so it’s not a safe first step. Lowering the platform manually is dangerous unless the system is designed for safe manual descent and you have proper procedures and personnel; attempting it without that can lead to a fall or another entrapment. Calling a supervisor is important, but the immediate actions to control the hazard should come first. After stopping and isolating power, notify the supervisor or maintenance team for a safe inspection and follow lockout/tagout and repair procedures as required.
