FLSD Building Systems Oversight 4

Question 1

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?

Accepted Answer

Loss of cooling may cause server room overheating and potential electrical fires

Answer

Chiller failures can cause critical spaces like server rooms to overheat, creating electrical fire risks that the FLSD must monitor and mitigate.

Question 2

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?

Accepted Answer

Document the overload and schedule load shedding of non-critical systems

Answer

An overloaded generator must have non-critical loads shed to bring consumption within rated capacity and ensure life safety systems remain powered.

Question 3

Under NYC FC, how frequently must a high-rise building's fire pump be subjected to a full flow test (annual flow test)?

Accepted Answer

Annually

Answer

NFPA 25 and NYC FC require annual full-flow testing of fire pumps to verify they meet rated performance.

Question 4

Which building system component is responsible for maintaining positive pressure in stairwells during a fire to prevent smoke infiltration?

Accepted Answer

Stairwell pressurization fans

Answer

Stairwell pressurization fans inject fresh air to maintain pressure differentials that prevent smoke from entering evacuation routes.

Question 5

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?

Accepted Answer

The system is deficient and likely cannot meet flow requirements

Answer

A static pressure well below the required residual pressure under flow strongly indicates the system cannot deliver minimum required pressure during firefighting operations.
