🔍 Key Concepts
• Class A fires involve ordinary combustibles like wood, paper, cloth, and some plastics
• On fire control plans, different extinguishing agents (water, foam, CO₂) have distinct symbols
• CO₂ extinguishers are usually preferred for electrical/Class B–C fires, not basic Class A combustibles
đź’ Think About
• First, identify what type of extinguishing agent each numbered symbol (47, 36, 56, 26) represents on the plan
• Then, think about which of those agents is normally considered most effective and primary for cooling and soaking burning solids like wood or paper, rather than just smothering
• Ask yourself which symbol clearly shows CO₂, and which ones indicate water or foam hoses/reels
âś… Before You Answer
• Be sure you can match each option number to the correct symbol in the illustration and name its agent/device (e.g., CO₂ extinguisher, water hose reel, foam hose reel, monitor, etc.)
• Confirm from your basic firefighting knowledge which agents are recommended for Class A fires (cool and soak) versus which are mainly for Class B/C or electrical fires
• Double‑check that the symbol you choose represents an agent that can apply water or foam continuously, not just a short‑duration discharge like a small portable extinguisher
