What does this sign mean?
Class 1 covers explosive substances and articles such as TNT, fireworks, detonators and the blasting charges used in mining. The orange diamond with the exploding-bomb symbol announces from a distance that the hazard here is an explosion whose effects can reach well beyond the package, not a local fire.
Where does it go and when is it required?
