No Drinking Water Sign - Meaning and Usage Guidelines #3821331 (License: Personal Use)

The image displays a standardized 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 indicates that the water source is unsafe for human consumption, often due to contamination, chemical treatment, or non-potable supply. It is frequently posted near utility sinks, construction sites, laboratories, or outdoor fixtures where water is intended only for cleaning or industrial use.

This sign is used in public facilities, workplaces, schools, and construction zones to prevent accidental ingestion of non-potable water. It aligns with OSHA, ANSI, and ISO safety signage standards and addresses user intent around hazard awareness, regulatory compliance, and health protection.
