FLSD Fire Suppression Systems 2

Question 1

Which NFPA standard establishes requirements for inspection, testing, and maintenance of water-based fire protection systems?

Accepted Answer

NFPA 25

Answer

NFPA 25 is the Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems, covering sprinklers, standpipes, and related equipment.

Question 2

How often must a main drain test be performed on a wet pipe sprinkler system per NFPA 25?

Accepted Answer

Annually

Answer

NFPA 25 requires an annual main drain test to verify adequate water supply and detect potential obstructions in the sprinkler system piping.

Question 3

How does a deluge sprinkler system differ from other sprinkler system types?

Accepted Answer

All sprinkler heads are open and water flows from every head simultaneously upon activation

Answer

In a deluge system all sprinkler heads are open (no fusible elements), so when the system activates, water flows simultaneously from every head in the protected area.

Question 4

Per NFPA 13, what is the minimum required clearance between sprinkler head deflectors and the top of stored materials?

Accepted Answer

18 inches

Answer

NFPA 13 requires a minimum 18-inch clearance between sprinkler deflectors and the top of storage to allow proper water distribution pattern below the heads.

Question 5

When a sprinkler system must be taken out of service for maintenance, what must the FLSD implement per NFPA 25?

Accepted Answer

An impairment program that includes a fire watch

Answer

NFPA 25 requires a formal impairment program when a water-based fire suppression system is out of service, which must include a fire watch to compensate for the loss of automatic protection.
