Using a lockout/tagout system is crucial for ensuring safety during maintenance and servicing of equipment. This system is designed to prevent accidental start-up or release of hazardous energy while workers are performing their tasks. The correct answer states that the lockout/tagout system should be used to ensure equipment is properly shut off and not able to be restarted. By locking out the equipment and placing a tag indicating that service is being performed, it effectively communicates to others that they should not attempt to operate the equipment. This practice is vital in any scenario where unexpected energization could lead to accidents or injuries. In contrast, simply using the system while the equipment is functioning normally, while preparing to shut down the equipment, or only during routine inspections does not address the core purpose of lockout/tagout procedures. It’s essential to implement these measures when maintenance occurs, regardless of the equipment's operational status, ensuring that equipment remains in a safe state until all tasks are completed.
