Final answer:
The primary responsibility for a daily walk-around to ensure safety and optimal operation typically lies with the operator, such as a pilot or surgeon, who uses checklists as a procedural guide.
Step-by-step explanation:
The primary responsibility for ensuring a daily walk-around is performed typically rests with the operator of the equipment or the vehicle, such as a pilot in the context of the airline industry, or a surgeon in a medical facility. The walk-around is a type of checklist procedure designed to assess various components for safety and functionality before operation begins. In aviation, it is the pilot who must conduct a thorough pre-flight inspection per Federal Aviation Administration (FAA) regulations, which contributes to ensuring the safety of the flight. Similarly, in healthcare settings, surgical teams utilize checklists, such as the WHO surgical safety checklist, to help prevent workplace accidents and ensure patient safety.
