Question 1

What is the required density for a warehouse with 10 ft (3 m) deep multiple-row racks without an in-rack sprinkler

system that contains a nonencapsulated storing Class IlI commodity on wooden pallets and has a storage height of

18 ft (5.4 m) and 8 ft (2.4 m) aisles, and is using standard, ordinary temperature sprinkler heads?

A0.25 gpm/ft2 (10.2 mm/min)

B0.33 gpm/ft2 (13 mm/min)

C0.44 gpm/ft2 (17.9 mm/min)

D0.52 gpm/ft2 (20.8 mm/min)

Answer : B

For a warehouse with the described characteristics, a design density of 0.33 gpm/ft is a common requirement to ensure adequate protection for Class III commodities on wooden pallets, taking into account the storage configuration and commodity type.

Question 2

Which type of pipe does not require a special listing to use threaded fittings?

ASchedule 5

BSchedule 7

CSchedule 10

DSchedule 40

Answer : D

Schedule 40 pipe does not require a special listing to use threaded fittings, as it is a common standard for pipe thickness and is widely used in fire protection systems for its durability and compatibility with standard fittings.

Question 3

What is the maximum distance of the top of the post on a post indicator valve from final grade?

A36 in. (900 mm)

B40 in. (1000 mm)

C48 in. (1200 mm)

D50 in. (1250 mm)

Answer : B

Post Indicator Valves

6.3.1

Where post indicator valves are used, they shall be set so that the top of each post is 32 in. to 40 in. (800 mm to 1.0 m) above the final grade.

Question 4

A five story building is proposed, with the ground floor being used for retail space and the upper four floors for

apartments. There is no 3-hour rated building separation between the retail and residential spaces. Which standard is

applicable for the design of the fire sprinkler system?

ANFPA 13

BNFPA 13D

CNFPA 13R

DNFPA 20

Answer : A

NFPA 13 is the applicable standard for the design of the fire sprinkler system in a mixed-use building with retail space and residential apartments without a 3-hour rated separation. NFPA 13 provides comprehensive coverage for commercial and residential spaces in multi-use buildings.

Question 5

The minimum flow rate for the required forward flow test of a backflow prevention assembly shall be the

Alisted flow rate of the device.

Bmaximum flow rate of the device.

Csystem demand excluding hose stream allowance, where applicable.

Dsystem demand plus hose stream allowance, where applicable.

Answer : D

The minimum flow rate for the forward flow test of a backflow prevention assembly should be the system demand plus hose stream allowance, where applicable, to ensure the assembly can handle the maximum expected flow during a fire event.

Question 6

What standard applies for underground malleable iron threaded fittings of Class 150?

AASME B16.1

BASME B16.3

CASME B16.4

DASME B16.5

Answer : B

ASME B16.3 is the standard that applies to malleable iron threaded fittings of Class 150, which are commonly used in piping systems, including those for fire protection. This standard covers dimensions, tolerances, and material requirements for these types of fittings.

Question 7

What is the minimum design criteria to protect an exposed nonexpanded Group A plastic stored in a solid pile to a maximum height of 15 ft (4.6 m) in a 26 ft (7.9 m) high building? Piles to be stable with closed arrays.

A0.70 gpm/ft2 over 2000 ft2 (28.5 mm/min over 186 m2)

B0.70 gpm/ft2 over 2500 ft2 (28.5 mm/min over 232 m2)

C0.85 gpm/ft2 over 2000 ft2 (34.6 mm/min over 186 m2)

D0.85 gpm/ft2 over 2500 ft2 (34.6 mm/min over 232 m2)

Answer : A

To protect exposed nonexpanded Group A plastic stored in a solid pile up to 15 ft high, a design criteria of 0.70 gpm/ft over 2000 ft is typically required. This density and area coverage account for the high combustibility and potential heat release of Group A plastics.
