A missing FDC cap leaves the connection vulnerable to debris, vandalism, or obstruction, which could prevent the fire department from connecting their hoses during an emergency. Replacing the cap immediately protects the connection's integrity, and reporting it ensures building management is aware and can address any underlying issues. This action maintains the system's readiness for critical use.

Question 2: Hose connections and caps must be inspected for what frequency to ensure they are not damaged or missing?

Annually (Correct answer)
Monthly
Weekly
Quarterly

Correct answer: Annually

Hose connections are inspected annually as part of the overall system inspection. This check ensures the threads are not damaged, gaskets are in place, and caps are securely fitted to prevent debris from entering the system.

Question 3: What is the defining characteristic of an 'automatic wet' standpipe system?

The piping is normally empty and requires the fire pump to be manually started.
The piping is normally filled with pressurized air.
The piping is constantly filled with water under pressure and is available for immediate use. (Correct answer)
The piping is filled with water, but the water is not pressurized.

Correct answer: The piping is constantly filled with water under pressure and is available for immediate use.

An automatic wet standpipe system has its piping constantly filled with water under pressure from a dedicated supply. This allows for immediate water flow as soon as a hose valve is opened, making it the quickest and most reliable type of system.

Question 4: A manual dry standpipe system relies on what source for its water supply during a fire?

A rooftop gravity tank that opens automatically.
The Fire Department pumping water into the Fire Department Connection (FDC). (Correct answer)
The building's domestic water tank.
An automatic fire pump connected to the city water main.

Correct answer: The Fire Department pumping water into the Fire Department Connection (FDC).

A manual dry standpipe system contains no water and has no dedicated water supply connected to it. It is entirely dependent on the Fire Department to arrive, connect their pumper trucks to the FDC, and supply the system with water.

Question 5: A Class I standpipe system is designed for use by:

Building occupants only.
Both building occupants and the Fire Department.
The Fire Department and trained fire brigade members. (Correct answer)
Sprinkler system technicians only.

Class I systems are designed for use by firefighters and those trained in handling heavy fire streams. They feature 2.5-inch hose connections to provide a large volume of water necessary for professional firefighting operations.

Question 6: During a weekly inspection, a control valve is found to be closed. After reopening it, what is the minimum information that must be recorded in the logbook?

A note that the valve was checked.
Just the date and the C of F holder's signature.
The date, condition found, corrective action taken, and C of F holder's signature. (Correct answer)
The time of day the valve was found closed.

Correct answer: The date, condition found, corrective action taken, and C of F holder's signature.

A complete logbook entry for a deficiency must include the date, a description of the condition found (valve closed), the corrective action taken (valve reopened), and the name and signature of the S-13 C of F holder who performed the action. This creates a clear and accountable record.

Question 7: What is the first action an S-13 holder must take upon discovering a standpipe system impairment?

Notify the building owner or representative (Correct answer)
Immediately begin repairs
Call the FDNY Borough Dispatcher
Place red tags on the system

Correct answer: Notify the building owner or representative

The first step is to notify the building owner or their representative. This ensures that the responsible party is aware of the situation and can authorize the necessary actions, including repairs and notifications to the FDNY.

Question 8: What is the function of the check valve located in the piping behind the FDC?

It automatically alerts the fire department when used.
It reduces the pressure from the FDNY pumper.
It mixes foam concentrate with the water.
It prevents water from the system from flowing back out of the FDC. (Correct answer)

Correct answer: It prevents water from the system from flowing back out of the FDC.

The check valve is a one-way valve that allows water from the FDNY pumper to flow into the standpipe system. It also automatically closes to prevent the pressurized water from the building's fire pump or gravity tank from flowing back out through the FDC.

Question 9: What is the purpose of FDNY Rules and Regulations regarding standpipe systems?

To ensure that standpipe systems are properly installed, maintained, and operational during emergencies (Correct answer)
To monitor water quality
To train firefighters in plumbing skills

Correct answer: To ensure that standpipe systems are properly installed, maintained, and operational during emergencies

FDNY rules and regulations are established to safeguard lives and property by setting strict standards for fire protection systems. For standpipe systems, these regulations mandate proper design, installation, regular maintenance, and testing protocols. Adherence ensures the systems are reliable and fully functional, providing essential water for firefighting when an emergency occurs.

Question 10: A standpipe system serving a building more than 300 feet tall typically requires which of the following water supply configurations?

City main pressure alone with a jockey pump
A zoned standpipe system with multiple pumps in series or a high-pressure booster arrangement (Correct answer)
Two jockey pumps operating in parallel
A single fire pump and one gravity tank

Correct answer: A zoned standpipe system with multiple pumps in series or a high-pressure booster arrangement

Buildings over 300 feet require zoned standpipe systems with multiple pumps arranged in series or staged pressure zones because a single pump cannot safely provide adequate pressure to very high floors without over-pressurizing lower floors.

Question 11: The main drain test for a standpipe system should be performed at what minimum frequency?

Monthly
Annually (Correct answer)
Quarterly
Weekly

Correct answer: Annually

The main drain test is conducted annually to check the condition of the water supply. It involves recording the static and residual pressures to detect any significant changes that might indicate a problem like a partially closed valve or obstruction in the supply line.

Question 12: What should be done if a standpipe system is found to be out of service?

Wait until the next scheduled maintenance to address the problem
Report the issue immediately and take steps to restore the system as quickly as possible (Correct answer)
Inform the building management only
Ignore the issue and continue regular duties

Correct answer: Report the issue immediately and take steps to restore the system as quickly as possible

A non-operational standpipe system poses a significant fire safety hazard, as it compromises the building's ability to fight fires. Therefore, immediate reporting to relevant authorities (like the FDNY and building management) and prompt action to restore its functionality are critical. This ensures the building's fire protection capabilities are reinstated without delay, minimizing risk.

Question 13: For an unplanned out-of-service condition lasting more than 4 hours, what additional precaution is required?
