CPS CPS Firefighter Test Map and Diagram Interpretation Questions and Answers 2 — Questions and Answers
Question 1: On a building floor plan, a dashed line typically represents which of the following?
- A load-bearing wall
- A hidden or overhead structural element (Correct answer)
- The shortest evacuation route
- A fire suppression pipe
Correct answer: A hidden or overhead structural element
Dashed lines on floor plans indicate elements that are hidden from view or located overhead, such as beams or upper-level features.
Question 2: A fire department connection (FDC) is shown on a site diagram. Where is it most likely positioned relative to the building?
- Inside the main lobby
- On the roof near the HVAC unit
- On the exterior wall or near the street side of the building (Correct answer)
- Adjacent to the electrical panel room
Correct answer: On the exterior wall or near the street side of the building
FDCs are placed on exterior walls or close to street access so fire apparatus can quickly connect hoses without entering the structure.
Question 3: A topographic map shows contour lines spaced very close together near a building. What does this indicate?
- Flat terrain ideal for staging equipment
- A steep slope that may affect ladder placement and hose lays (Correct answer)
- Underground utility corridors
- High population density in the area
Correct answer: A steep slope that may affect ladder placement and hose lays
Closely spaced contour lines represent steep elevation changes, which affect apparatus positioning and hose deployment tactics.
Question 4: On a fire pre-plan diagram, the symbol 'OS&Y' next to a valve icon stands for what?
- Open Stand and Yield
- Outside Screw and Yoke (Correct answer)
- Overhead Supply and Yard
- Operational Safety and Yield

OS&Y (Outside Screw and Yoke) is a type of gate valve whose open/closed status can be determined visually by the position of the stem.

- Class A only
- Class B only (Correct answer)
- Class C only
- Class B and C
Correct answer: Class B only
Class B standpipe systems have small 1½-inch hose connections intended for occupant use and rely on the fire department to boost pressure during emergencies.

- A one-way street
- A road closed or under construction (Correct answer)

Correct answer: A road closed or under construction
Parallel diagonal lines (hatching) across a road on emergency maps indicate a road closure or construction zone that restricts vehicle access.
