Durable Class 4 Flammable Solids Signage

Our Class 4 hazard diamonds use bold symbols and bright orange backgrounds to ensure instant recognition. Made from tough, weather-resistant materials, they remain visible in warehouses, laboratories, and transport vehicles handling dangerous solids.

Class 4 Subcategories

We supply all Class 4 Diamonds for accurate hazard identification:

• Class 4.1 – Flammable Solid: Substances that can ignite easily and burn rapidly.
• Class 4.2 – Spontaneously Combustible: Materials that ignite without an external source of heat.
• Class 4.3 – Dangerous When Wet: Substances that emit flammable gases when in contact with water.
