No Drinking Water Sign - Visual Warning for Unsafe Water Sources #3313326 (License: Personal Use)

The image features a standard prohibition symbol-a bold red circle with a diagonal slash-overlaid on a stylized gray faucet dispensing into a black drinking glass. The design follows ISO and ANSI safety signage conventions, using high-contrast colors (red, black, white, and gray) for maximum visibility and immediate recognition. It conveys a clear, non-verbal warning applicable in public facilities, construction sites, or emergency zones where water quality is compromised.

Commonly used in plumbing areas, industrial sites, disaster relief zones, or temporary facilities to indicate non-potable water. Matches user intent for safety compliance, hazard communication, or facility management guidance.
