🔍 Key Concepts

• Study how pumps are shown on this Fire Control Plan versus how valves are shown (look at symbols in the 30s and 50s range). • Notice that fire pumps and bilge pumps often use a similar basic pump symbol, but fire pumps are usually marked with a letter like P or F. • Compare the shapes and shading of symbols 19, 21, 22, and 54 and ask which one really looks like a pump impeller rather than a valve or damper.

💭 Think About

• Which of the four choices most closely matches the style of other known pump symbols on this sheet (for example, item 45 for a fire pump)? • Which of the four symbols looks more like a valve symbol (triangle in a circle or wedge with a line) that you can rule out right away? • Among the remaining symbols, which one is a plain pump symbol without any extra letters that would indicate a fire or sprinkler pump?

✅ Before You Answer

• Verify which symbol numbers in the sheet are clearly labeled pumps (e.g., fire pump, sprinkler pump) and see what base shape they share. • Confirm that you can distinguish the valve symbols (triangles in circles or between lines) from rotating pump symbols before choosing. • Double‑check that the option you pick does not contain any marking that would limit it to a specific fire‑fighting system (like a "P" or "F" for fire pump).
