Question: 1 / 400

What color should non-potable water hoses typically be to avoid confusion with potable hoses?

Blue

Grey

Yellow

Non-potable water hoses are typically colored yellow to clearly distinguish them from potable water hoses. The purpose of this color-coding is to prevent any mix-up that could result in the use of non-potable water for drinking, cooking, or any other activities requiring safe water. The yellow color serves as a visual alert to users that the water within those hoses is not safe for consumption. This standard practice helps ensure safety and compliance with regulations concerning water quality. The use of other colors, such as blue for potable water, is intentionally designed to promote this clear distinction and reduce risks associated with water contamination.
