Which routine maintenance can be performed by instructors familiar with the equipment?

Routine maintenance that can be performed by instructors familiar with the equipment includes tasks that ensure the equipment remains functional and in good working order. Replacing projector bulbs is a specific maintenance task that instructors can typically handle, as it often involves straightforward procedures that do not require advanced technical knowledge or specialized tools. Instructors are trained to interact with and operate the training equipment, which includes understanding the issues that may arise, such as a burned-out bulb.

Other options, while appearing to be maintenance-related, may involve more specialized knowledge or skills. For instance, replacing cooling fans in manikins may require technical proficiency and understanding of the internal workings that an instructor might not possess. Removing dust covers over equipment can generally be seen as a basic task, but it might not be categorized as true maintenance in the same sense as replacing parts. Wrapping power cords around equipment is more about organization than maintenance, so it may not fit the criteria of routine maintenance either. Thus, the option that stands out as a practical maintenance task is indeed replacing projector bulbs, which can be effectively carried out by instructors who are familiar with the equipment.
