FLSD FLSD Fire Prevention and Inspection 5

Question 1

A building's fire pump fails its annual flow test, producing only 60% of its rated pressure at peak flow. What is the required response?

Accepted Answer

Take the fire pump out of service and notify the fire department and building management immediately

Answer

A fire pump that cannot meet its rated performance compromises the entire sprinkler and standpipe system and must be taken out of service pending repair, with the Authority Having Jurisdiction notified.

Question 2

Under NFPA 72, what is the maximum allowable distance between heat detectors in a smooth-ceiling area with a standard 10-foot ceiling height?

Accepted Answer

50 feet between detectors in any direction

Answer

NFPA 72 specifies that heat detectors on smooth ceilings up to 10 feet high may be spaced no more than 50 feet apart in any direction.

Question 3

Which scenario correctly describes when a hot work permit is required in a New York City high-rise building?

Accepted Answer

Any time welding, cutting, or grinding operations that produce sparks or open flame are performed outside a designated shop area

Answer

Hot work permits are required for any spark- or flame-producing operations performed outside permanently protected shop areas, regardless of time of day or proximity to sprinklers.

Question 4

An office floor has portable space heaters plugged into power strips that are daisy-chained together. Why is this a fire hazard?

Accepted Answer

Space heaters must be plugged directly into wall outlets because they draw high current that can overheat power strips and extension cords

Answer

Space heaters draw significant amperage and must be plugged directly into grounded wall outlets; using power strips or extension cords creates an overload and fire risk.

Question 5

A building's emergency voice/alarm communication system (EVACS) fails to produce intelligible speech on three upper floors during a test. What standard governs the intelligibility requirement?

Accepted Answer

NFPA 72, which requires speech intelligibility to meet a common intelligibility scale (CIS) of 0.70 or higher

Answer

NFPA 72 requires that EVACS systems achieve a speech transmission index (STI) or common intelligibility scale (CIS) score of at least 0.70 to ensure occupants clearly understand emergency instructions.
