No Drinking Water Sign - Prohibition Symbol for Unsafe Tap Water #1630621 (License: Personal Use)

The image displays a standard prohibition sign: a red circle with a diagonal slash over a black pictogram of a faucet dispensing water into a cup. This universally recognized symbol communicates that the water from this source must not be consumed due to contamination, chemical treatment, or lack of potability certification. It is often placed near non-potable water outlets in industrial, municipal, or disaster-response settings.

This image is typically used on safety signage, public health advisories, facility management guides, and emergency response materials. It serves users seeking to identify unsafe water sources quickly, especially in contexts like construction zones, camping areas, or post-disaster environments where water quality is uncertain.
