Dry powder extinguishers are indicated by a blue panel above the operating instructions on a red cylinder. The blue panel signifies a blue-labelled extinguisher, commonly referred to as ABC extinguishers, suitable for Class A, B, and C fires and often used in electrical-fire scenarios up to a certain voltage. This blue panel is the key visual cue that distinguishes dry powder extinguishers from other types in the UK color-coding system.
If you’d like, I can summarize the standard UK extinguisher color codes for quick reference:
- Blue panel on red body: Dry powder (A, B, C, and some electrical fires)
- Black panel on red body: CO2 (electrical fires and some liquids)
- Cream panel on red body: Foam (A and B)
- Red body with no special panel or other panels: Water or water mist (A only, depending on model)
- Yellow panel: Wet chemical (primarily kitchen fires)
Note: Some sources note variations or updates in labeling conventions over time, and it’s always best to check the specific extinguisher’s label on the unit itself for authoritative guidance. If you need, I can compile a concise visual checklist you can print for quick on-site reference.
