GHS01 Explosion Hazard Labels

GHS01 Explosion Hazard Labels

GHS01 is one of the globally recognized hazard pictograms defined by the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). This label specifically indicates explosive hazards.

What Is GHS01?

GHS01 is the explosive hazard symbol defined under the Globally Harmonized System of Classification and Labelling of Chemicals (GHS). This internationally recognized label is used to indicate substances or mixtures that may explode under certain conditions such as heat, shock, or friction.

The label features a bold exploding bomb icon within a red diamond border — an immediate visual cue for danger.

When Is the GHS01 Label Required?

The GHS01 hazard pictogram is required for chemicals or materials classified as:

Explosive

Self-reactive substances and mixtures (Type A & B)

Organic peroxides (Type A & B)

Pyrotechnic substances

Desensitized explosives

If a product poses a risk of detonation, deflagration, or explosive decomposition, it must carry this label as part of its hazard communication.

Why Is GHS01 Important?

• Protects Workers and the Public – Ensures awareness and promotes safe handling of potentially explosive materials.
• Prevents Accidents – Proper labeling minimizes risks in transport, storage, and use — reducing the chance of explosions.
• Enables Regulatory Compliance – Fulfills legal obligations under global and regional safety standards (e.g., OSHA, CLP, UN GHS).
• Supports Emergency Response – Helps first responders assess dangers quickly in the event of an accident or fire.

Where to Use GHS01 Labels

• Chemical manufacturing plants
• Laboratories
• Warehouses and storage units
• Transport containers
• Industrial facilities handling explosives or reactive chemicals
