No Drinking Water Sign - Safety Symbol & Usage Guide #3313318 (License: Personal Use)

The image displays a standard prohibition symbol: a black outline of a glass filled with liquid, overlaid with a bold red circle and diagonal slash. This universally recognized icon signals that the water source is contaminated, non-potable, or otherwise unsafe for human consumption. It is commonly posted near industrial tanks, construction sites, or emergency water stations where water may contain chemicals, pathogens, or debris.

Used on signage in factories, labs, construction zones, disaster relief areas, and public facilities to prevent accidental ingestion of unsafe water; matches user intent for safety compliance, hazard awareness, or emergency preparedness guidance.
