Which tool is considered useful when inspecting complex facilities?

When inspecting complex facilities, a variety of tools can enhance the thoroughness and accuracy of the assessment. Each of the listed tools serves a specific purpose that contributes to a comprehensive evaluation.

A thermometer is essential for measuring temperature conditions within a facility, which can affect both environmental quality and operational efficiency. Monitoring temperature is crucial in settings where precise climatic conditions are necessary, such as in laboratories or food storage areas.

A clipboard serves a vital organizational function, allowing inspectors to take notes, reference checklists, and keep track of observations in an orderly manner. This ensures that all facets of the inspection are documented properly, promoting thoroughness and accountability.

A light meter is important in assessing the adequacy of lighting within the facility. Proper lighting is crucial for safety, productivity, and overall comfort, especially in work environments where visibility impacts both tasks and safety protocols.

Given that all these tools—thermometer, clipboard, and light meter—address different aspects of facility inspection, their combined use ensures a multifaceted approach to assessment. This is why the option suggesting all of them is the best choice, as it recognizes the diverse tools effective for inspecting complex environments.
