What must maintenance partners do before performing extended work in the wash alley?

Before performing extended work in the wash alley, maintenance partners must check in with the wash alley operator. This step is crucial because the wash alley is a critical area where operational activities are taking place, and coordination with the operator ensures that safety protocols are maintained. The operator can provide specific insights into the current operational conditions, any potential hazards, or ongoing tasks that could be affected by maintenance work. By checking in, maintenance partners can confirm that it is safe to proceed with their work and identify any specific precautions they need to take to avoid disrupting operations or risking safety.

The other options, while relevant to overall safety and operational effectiveness, do not specifically address the immediate need for direct communication and coordination with the operator at the wash alley.
