What is the minimum required rating for a fire door assembly installed in a 2-hour rated fire barrier?
Answer : C
The minimum required rating for a fire door assembly installed in a 2-hour rated fire barrier is 1-1/2 hours. According to NFPA 80, Standard for Fire Doors and Other Opening Protectives, fire door assemblies are typically rated at three-quarters of the rating of the wall in which they are installed. Thus, a 2-hour rated wall requires a 1-1/2-hour fire door assembly.

Which one of the following is an architectural drawing that shows the vertical view of a building, including floors, building height, and the grade of surrounding ground?
Answer : D
An elevation view is an architectural drawing that shows the vertical view of a building, including floors, building height, and the grade of surrounding ground. It is used to depict the exterior or interior walls of a structure from a vertical perspective. This view provides details on the heights of various building elements and their relationships to the surrounding terrain.
If a sprinkler system is supplied with water from a gravity tank, the gravity tank shall be installed in accordance with what standard in order to be acceptable as a source of water?
Answer : C
If a sprinkler system is supplied with water from a gravity tank, the tank must be installed in accordance with NFPA 22, Standard for Water Tanks for Private Fire Protection. NFPA 22 provides the requirements for the design, construction, installation, and maintenance of water tanks used for fire protection. It ensures that the gravity tank meets the necessary standards to be a reliable and effective water source for the sprinkler system.

What is the residual pressure according to the water supply graph?
Answer : B
To determine the residual pressure from the provided water supply graph, locate the appropriate point on the graph where the flow rate intersects with the pressure line. According to the graph, the residual pressure is around 42 psi (290 kPa), which matches option B. This value is determined by reading the vertical axis (pressure) at the point where the flow test results are plotted. The pressure reading corresponds to the data point on the dashed line provided in the water flow test summary sheet.
For detailed calculations, understanding, and verification, reference to NFPA standards, particularly those related to water flow testing, such as NFPA 13 or NFPA 25, would be necessary.
Where would you find information pertaining to the seismic load?
Answer : A
Information pertaining to seismic loads would be found in the structural plans. These plans contain details about the building's framework and its ability to resist seismic forces. The structural plans include calculations and specifications that ensure the building's integrity under seismic stress, following relevant codes such as the International Building Code (IBC) and NFPA 5000.
