flow.
**Question 9.** Which type of standpipe system relies on the fire department’s pumpers to develop
pressure after water is supplied?
A) Automatic-Wet
B) Manual-Wet
C) Automatic-Dry
D) Manual-Dry
Answer: B
Explanation: Manual-Wet systems are filled with water but depend on FD pumpers for the necessary

**Question 12.** Which color coding identifies a standpipe fire department connection (FDC) according
to FDNY standards?
A) Green
B) Red
C) Blue
D) Yellow
Answer: B
Explanation: Red caps or markings denote standpipe FDCs, distinguishing them from sprinkler (green) or
