Exploding bomb (GHS01)
The GHS pictogram for explosives, and for self-reactive substances and organic peroxides that can explode when heated.
These identify the hazard class a pictogram represents. For handling, storage and first aid, refer to the product's label and safety data sheet.
How to read it
It is GHS01 in the international numbering. On US workplace labels, OSHA’s Hazard Communication Standard assigns it to explosives and to self-reactive substances and organic peroxides of type A, for which the hazard statement reads “Heating may cause an explosion”. For the next type down, type B, the label carries the exploding bomb and the Flame (GHS02) together. In Great Britain the pictogram is simply called Explosive.

Differences by country or standard
Canada’s WHMIS lists the exploding bomb for self-reactive substances and mixtures and for organic peroxides of types A and B, with the flame added for type B, as in the United States.
