What does the term "readily visible" refer to in the context of inspection?

The term "readily visible" refers to elements that can be clearly seen without the need for specialized tools or equipment. This means that during an inspection, a septic inspector can observe these features or conditions using only their eyes, enhancing the efficiency of the inspection process. Being able to identify issues quickly based on visual cues is essential in septic inspections, as it allows the inspector to determine the condition of the system without unnecessary delay.

In the context of the other choices, visibility under specific conditions, such as only in sunlight, or the need for specialized equipment, does not fit the definition of "readily visible." Using simple tools may assist in the inspection, but the core concept of "readily visible" emphasizes the ability to see without reliance on any tools, aligning with the primary intent of the inspection process. This understanding is vital for inspectors to effectively carry out their duties in evaluating septic systems.
