What system must an authorized partner follow to enter the wash alley?

The correct choice is the Buddy System or manual mode because it emphasizes safety by ensuring that no individual is entering potentially hazardous areas alone. The Buddy System requires that two or more individuals enter together, allowing them to support one another and respond effectively if any emergencies arise. This system promotes communication and ensures that assistance is readily available in case of an accident, enhancing overall safety in the wash alley.

Using the Buddy System is crucial in environments where equipment and processes pose risks, as partners can watch out for each other and provide immediate help if needed. Manual mode may also allow for a higher level of control over safety measures when navigating the wash alley, ensuring that procedures are actively monitored.

While solo entry procedures, emergency protocols, and supervised entry could provide safety alternatives, the Buddy System is specifically designed to foster teamwork and mutual vigilance, making it the best choice for entering areas that may have inherent dangers.
