Xn - Nocif Hazard Symbol | Chemical Safety Warning Sign #1806342 (License: Personal Use)

The image displays the former EU hazard symbol for “Xn - Nocif,” denoting substances that are harmful (but not highly toxic) upon exposure. It features a bold black X on an orange square background, with the classification code and French term “Nocif” beneath. This symbol was used under the Dangerous Substances Directive (67/548/EEC) before being replaced by the GHS-based CLP regulation.
