NEW QUESTION # 29
Exhibit.
What does point "A" on the water supply graph represent?
- A. Optimized pressure
- B. Maximum available water
- C. Static pressure
- D. Residual pressure
Answer: C
Explanation:
Point "A" on the water supply graph represents the static pressure. Static pressure is the pressure in the water supply system when no water is flowing. It is typically the highest pressure reading on the graph, measured before any hydrants are opened for testing or fire suppression activities. Understanding static pressure is crucial for designing fire protection systems and ensuring adequate water supply and pressure is maintained throughout the fire suppression operation as outlined in NFPA 13, Standard for the Installation of Sprinkler Systems.

NEW QUESTION # 38
Exhibit.
What is the occupancy classification of the conference rooms in the figure if they are used for meetings of less than 50 people?
- A. Educational
- B. Business
- C. Assembly
- D. Mercantile
Answer: B
Explanation:
According to NFPA 101, Life Safety Code, conference rooms that are used for meetings with less than 50 people are typically classified under the "Business" occupancy classification (NFPA 101, Chapter 6). This is because such small meetings are considered part of the normal operations of a business environment, and thus, the rooms are not considered "Assembly" occupancy, which requires a larger number of people (usually
50 or more).
NEW QUESTION # 39
Exhibit.
On plan A12 what occupant load factor would you use?
- A. 100 ft2 (9 3 m2)
- B. 50 ft2 (4 6 m2)
- C. 200 ft2 (18 6 m2)
- D. 30 ft2 (2 8 m2)
Answer: D
Explanation:
On plan A12, the occupant load factor to use is 30 ft² (2.8 m²) per person. This factor is used to calculate the maximum number of occupants for a given space based on its size and usage, ensuring that the building adheres to safe occupancy levels as required by fire safety codes. The occupant load factor is determined by the type of occupancy and activity level within the space and is outlined in NFPA 101, Life Safety Code, which provides guidelines for calculating occupant loads to ensure safety during an emergency evacuation.
