In illustration D039SA below, what is the fire control plan symbol represented by number (39)?

🔍 Key Concepts

• Look closely at symbol (39): notice the small device shape at the bottom and what is drawn above it that looks like a protective cover or spray pattern. • Compare symbol (39) with symbol (28) in the first part of the sheet and with the labeled extinguisher line-up at (57). • Think about how fixed fire-fighting systems are usually shown differently from portable extinguishers and simple media types (like water or foam) on fire control plans.

💭 Think About

• Does symbol (39) show a particular extinguishing MEDIUM (like water or foam), or does it show a specific TYPE of system that might use that medium? • If you covered up the word under (39), which choice still makes sense just from the picture of the piping/head and the protective ‘umbrella’ shape? • How would a plan distinguish between plain water available for many uses and an automatic ceiling-mounted system installed over an area?

✅ Before You Answer

• Verify whether fire plan symbols for water or foam by themselves usually appear as simple shapes or as equipment heads/nozzles. • Check if there is any other clearly labeled sprinkler-related symbol on the sheet and compare its style with (39). • Confirm that your choice matches a fixed overhead fire-fighting system rather than just the extinguishing agent.
