What is the class/rating for the EFRS Drychem extinguisher?

• A. 10A120BC
• B. 10BC
• C. 14kg
• D. METAL X

Answer: (A)

The rating on a portable extinguisher shows what size of fires it can handle and which classes it covers. For a Drychem extinguisher, the format 10A120BC breaks down into two parts: 10A means it can handle a small to moderate Class A fire (wood, paper, textiles) with that many “A” units of extinguishing capacity. The 120BC part indicates its capability for Class B (flammable liquids) and Class C (energized electrical) fires, expressed as a combined BC rating. In other words, this extinguisher is multipurpose: it’s capable against ordinary combustibles and also effective for flammable liquids and electrical fires.

The other options don’t fit because they either miss the A rating (failing to specify its Class A capacity), or they refer to weight or a brand/type rather than the fire-class rating.
