Prohibition Symbol - Universal No Entry Sign for Safety and Compliance #189752 (License: Personal Use)

The image displays a standard prohibition sign: a thick red circle enclosing a red diagonal cross (X) over a black background, following ISO 3864-1 safety color standards. Its high-contrast design ensures immediate recognition across languages and contexts, making it ideal for warning against hazards, restricted access, or banned behaviors. Widely used in public spaces, industrial sites, and digital interfaces to enforce rules and prevent accidents.

Used on safety signage, regulatory documentation, websites (e.g., error states, disabled features), and instructional materials where visual communication of restriction is critical; matches user intent seeking clarity on prohibited actions or system limitations.
