Xn - Nocif Hazard Symbol | Chemical Safety Warning Sign #1423371 (License: Personal Use)

The image displays the former EU hazard symbol "Xn - Nocif", a black X on an orange square background, used to denote substances classified as harmful (Xn) under older chemical labeling regulations. The term "Nocif" is French for "harmful", reflecting multilingual labeling requirements in the European Union prior to CLP regulation adoption. This symbol was commonly found on chemical containers, safety data sheets, and workplace signage to alert users to potential health hazards like irritation or organ damage from short-term exposure.

This image is typically used in occupational safety training, chemical handling guides, regulatory compliance documentation, and historical comparisons of hazard labeling systems (e.g., transitioning from R-phrases to GHS/CLP). It matches user intent seeking to identify, understand, or comply with legacy chemical hazard communication standards.
