When a Fire Life Safety Director receives an alarm from the building automation system (BAS) indicating a chiller plant failure during summer, what is the primary fire safety concern?
Answer: Loss of cooling may cause server room overheating and potential electrical fires
Chiller failures can cause critical spaces like server rooms to overheat, creating electrical fire risks that the FLSD must monitor and mitigate.
A building's emergency generator is rated at 750 kW. During a power outage test, actual load measured is 820 kW. What action must the FLSD take?
Answer: Document the overload and schedule load shedding of non-critical systems
An overloaded generator must have non-critical loads shed to bring consumption within rated capacity and ensure life safety systems remain powered.
Under NYC FC, how frequently must a high-rise building's fire pump be subjected to a full flow test (annual flow test)?
Answer: Annually
NFPA 25 and NYC FC require annual full-flow testing of fire pumps to verify they meet rated performance.
Which building system component is responsible for maintaining positive pressure in stairwells during a fire to prevent smoke infiltration?
Answer: Stairwell pressurization fans
Stairwell pressurization fans inject fresh air to maintain pressure differentials that prevent smoke from entering evacuation routes.
A building's standpipe system shows a pressure reading of 65 psi at the highest outlet with no flow. FDNY requires a minimum residual pressure of 100 psi at the highest outlet under flow. What does this static reading indicate?
Answer: The system is deficient and likely cannot meet flow requirements
A static pressure well below the required residual pressure under flow strongly indicates the system cannot deliver minimum required pressure during firefighting operations.
During building systems oversight, an FLSD discovers that an elevator designated as a firefighters' service elevator has been placed out of service for modernization. What is the required action?
Answer: Notify FDNY and implement alternate arrangements as required by the fire safety plan
Taking a firefighters' service elevator out of service requires FDNY notification and implementation of compensatory measures per the approved fire safety plan.
What is the purpose of a fire department connection (FDC) on a building's sprinkler or standpipe system?
Answer: To allow FDNY to supplement system pressure and water supply using pumper apparatus
The FDC allows FDNY pumper trucks to inject additional water under pressure into the system when municipal supply alone is insufficient.
