UN Class 1.1 Explosive Hazard Sign - Safety Label for High-Explosive Materials #1821315 (License: Personal Use)

The image displays a standardized UN hazard placard for Class 1 explosives, specifically Division 1.1, indicating substances that pose a mass explosion hazard-meaning the entire load can detonate almost instantaneously. The black explosion pictogram and bold “1.1 * 1” designation follow international transport regulations (e.g., DOT, ADR, IMDG) to ensure safe handling, labeling, and emergency response.

Used on transport vehicles, shipping containers, and storage facilities for high-risk explosive materials like dynamite, TNT, or military ordnance; supports regulatory compliance and first responder identification.
