Which of the following is not a potential source for finding maintenance-related information?

The choice of the employee handbook as not being a potential source for finding maintenance-related information is appropriate because employee handbooks typically focus on policies, procedures, and general guidelines relevant to employment. They serve as a reference for workplace behavior, company policies, benefits, and rights, rather than detailing specific maintenance procedures or technical information related to equipment upkeep.

In contrast, a Maintenance Requirement Card is purposefully designed to provide specific instructions, requirements, and schedules for maintenance tasks. The Work Center Supervisor is often responsible for overseeing maintenance processes and can give detailed insights based on their experience and knowledge. The Equipment Maintenance Log is critical for recording all maintenance activities, issues, and history of repairs, serving as a vital source of information about equipment performance and past maintenance efforts. All these sources are directly tied to the maintenance functions, which is why the employee handbook is not included as a potential source for maintenance-related information.
