If a potable water hose is orange, what should be confirmed before use?

The correct choice emphasizes the importance of confirming that the hose is designated for potable water use. When a potable water hose is orange, it is a color-coded identification indicating that it is intended for drinking water and should be safe for human consumption. Before using the hose, one must verify that it hasn't been previously used for non-potable purposes, which could contaminate the water. Ensuring that the hose is unused helps maintain the integrity of the potable water supply, preventing health risks associated with contamination.

This protocol is crucial, especially in environments where various hoses may be used for different purposes, such as firefighting, irrigation, or industrial applications. In this context, verifying that a potable water hose is clean and free from any contaminants not only safeguards health but also upholds operational standards regarding water quality.
