No Drinking Water Sign - Meaning and Usage Guide #3098317 (License: Personal Use)

The image displays a standardized prohibition symbol: a black outline of a drinking glass containing wavy lines representing liquid, overlaid with a bold red diagonal slash inside a red circular border. This universally recognized icon warns that the water source is contaminated, non-potable, or otherwise unfit for human consumption. It is commonly placed near industrial tanks, irrigation systems, or untreated water outlets to prevent accidental ingestion.

Used on safety signage in public facilities, construction sites, parks, and industrial zones to alert people against drinking from non-potable water sources; matches user intent for hazard awareness, regulatory compliance, or emergency preparedness guidance.
