What is the first step to take when a milling machine is shut down for repair?

Lock out the main breaker box
Remove all tools from the table
Disconnect the power supply
Notify the supervisor

The correct answer is: Lock out the main breaker box

The correct choice emphasizes the importance of safety in a workshop environment, particularly when dealing with machinery like a milling machine. Locking out the main breaker box is a critical first step because it ensures that the machine cannot be inadvertently powered on while maintenance or repairs are being conducted. This action protects workers from the risk of electric shock and prevents potential accidents that could arise if the machine were to be accidentally activated during repair. By establishing a safe working environment through lockout/tagout procedures, technicians can effectively focus on the repairs without the constant concern of unexpected machine operation. Other actions, such as removing tools from the table, disconnecting the power supply, or notifying a supervisor, while important, may naturally follow the initial step of securing the machine's power to ensure safety. Safety protocols prioritize locking out energy sources before any interaction with the machine begins, reflecting best practices in industrial operations.
