FDNY Firefighting Operations and Equipment 2 — Questions and Answers
Question 1: When advancing a hoseline up a stairwell, the preferred method is to:
- Stretch the line straight up the center of the stairs
- Loop excess hose on each landing before advancing (Correct answer)
- Charge the line before entering the stairwell
- Have one firefighter carry all the hose at once
Correct answer: Loop excess hose on each landing before advancing
Looping excess hose on each landing prevents the weight of the hose from pulling back on the nozzle team and allows controlled advancement.
Question 2: The FDNY uses the term 'flat load' to describe which hose configuration?
- Hose folded in a figure-eight pattern
- Hose loaded in parallel folds flat in the bed (Correct answer)
- Hose coiled in a circular bundle
- Hose pre-connected to the pump panel
Correct answer: Hose loaded in parallel folds flat in the bed
A flat load consists of hose laid in parallel folds lying flat in the hose bed, allowing rapid deployment.
Question 3: Which nozzle type provides a fixed flow rate regardless of the pattern selected?
- Smooth bore nozzle
- Adjustable gallonage fog nozzle
- Automatic (constant pressure) nozzle (Correct answer)
- Cellar nozzle
Correct answer: Automatic (constant pressure) nozzle
Automatic nozzles maintain a constant pressure and flow rate automatically as the pattern is adjusted.
Question 4: At a high-rise fire, the attack hoseline should be connected to the standpipe outlet located:
- On the fire floor
- Two floors below the fire floor
- One floor below the fire floor (Correct answer)
- On the floor directly above the fire
Correct answer: One floor below the fire floor
FDNY procedure requires connecting to the standpipe outlet one floor below the fire floor to safely advance the line to the fire.
Question 5: What is the primary purpose of a water thief appliance?
- To boost water pressure in the supply line
- To allow multiple hoselines to be taken from a single supply line (Correct answer)
- To filter debris from the water supply
- To reduce water hammer in the system
Correct answer: To allow multiple hoselines to be taken from a single supply line
A water thief is a gated wye that allows two or more hoselines to be taken off a single supply line while controlling each independently.
Question 6: During overhaul operations, which gas is most dangerous because it is colorless, odorless, and produced by smoldering materials?
- Hydrogen sulfide
- Carbon monoxide (Correct answer)
- Ammonia
- Chlorine
Correct answer: Carbon monoxide
Carbon monoxide is colorless and odorless, produced during incomplete combustion, and is a leading cause of firefighter fatalities during overhaul.
Question 7: When operating at a cellar fire, the FDNY typically deploys which specialized tool to apply water without exposing firefighters to the fire area?
- Bresnan distributor (Correct answer)
- Piercing nozzle
- Distributor pipe
- Weed burner nozzle
Correct answer: Bresnan distributor
The Bresnan distributor is a rotating nozzle lowered through cellar openings to distribute water in a 360-degree pattern below without direct firefighter entry.
