🔍 Key Concepts

• Review the Fire Control Plan symbols for the bottom row (numbers 58–69) on Part 2 of the illustration. • Think about which symbols are used for electrical power sources versus fire‑extinguishing media such as gas or CO₂. • Notice how the plan uses letters like G and IG to indicate types of gas, and compare that to any symbol that suggests electricity or power generation.

💭 Think About

• Among 20, 32, 67, and 68, which one visually suggests an electrical power source rather than a gas system, extinguisher, or general marking? • Look at how gas systems (like CO₂, N₂, or inert gas) are drawn elsewhere in the plan—does any of the answer choices clearly follow that same style, and should an emergency generator look like a gas system? • Which of the symbols near the bottom right of the sheet appears to mark electrical equipment (hint: think of the common graphic used worldwide for electricity).

✅ Before You Answer

• Verify that you are not mixing up the symbol for gas extinguishing systems (general gas or inert gas) with the symbol for electrical power equipment. • Double‑check how the plan distinguishes lighting, emergency power, and gas systems—each has a different style or background color. • Before choosing, ask: "Does this symbol logically represent a machine that makes electricity in an emergency, or does it represent something else like gas, lighting, or just a label?"
