When quickly selecting a fire extinguisher for use on a sofa fire, the _____ would be the appropriate shape and color combination.

• A. blue square
• B. green triangle
• C. red circle
• D. orange diamond

Answer: (B)

Understanding how to pick an extinguisher quickly relies on color and shape cues that map to fire types. For a sofa fire, which involves ordinary combustibles like fabric and wood, the system uses a green triangle to signal suitability for these fires. That green triangle is the best match because it indicates an extinguisher meant for ordinary combustibles, making it appropriate for upholstery fires. The other combinations—blue square, red circle, orange diamond—point to different fire types or hazards in this coding system, so they wouldn’t be the right choice for a sofa fire. If unsure, prioritize safety by evacuating and calling for help.
