A portable extinguisher with a black hexagon on the label could be found in a _____.

• A. Commercial kitchen
• B. Office building
• C. Residential home
• D. Garage

Answer: (A)

The label symbol is telling you what environment and fire type the extinguisher is designed for. A black hexagon indicates this unit is intended for cooking-oil fires in a commercial kitchen. It uses a wet‑chemical agent that saponifies fats and oils, forming a soapy layer and cooling the oil to prevent re‑ignition, which is exactly the hazard found in busy kitchens. That's why this extinguisher belongs in a commercial kitchen, rather than in a residential home, an office, or a garage where different fire hazards and extinguisher types are preferred.
