Which standpipe type is explicitly listed in the material?

• A. Wet Standpipes
• B. Dry Standpipes
• C. Automatic Standpipes
• D. Manual Standpipes

Answer: (A)

Standpipe systems are distinguished by whether water is already in the piping. The material explicitly lists wet standpipes, meaning the piping is charged with water and pressurized at all times. That setup allows firefighters to immediately pull water from a standpipe outlet without waiting to charge the lines, which is why this is the correct choice. Dry standpipes, by contrast, are empty until charged, so water delivery isn't instant. Automatic or manual terms refer to how water is supplied or controlled, but the material’s stated standpipe type is wet standpipes, making it the best answer.
