NFPA Certified Fire Inspector I (CFI-1) Sample Questions (Q51-Q56):
NEW QUESTION # 51
Spray undercoating or spray body lining of vehicles shall be conducted a minimum of what distance from open flames or spark-producing equipment?
- A. 5 ft (1,524 mm)
- B. 3 ft (914 mm)
- C. 10 ft (3,048 mm)
- D. 20 ft (6,100 mm)
Answer: D
Explanation:
The minimum distance required for spray undercoating or spray body lining of vehicles from open flames or spark-producing equipment is specified in NFPA 33, Standard for Spray Application Using Flammable or Combustible Materials.
Spraying operations involving combustible coatings pose a significant fire risk due to flammable vapors, which can ignite from open flames or sparks.
To ensure safety, these operations must be conducted at least 20 feet (6,100 mm) away from ignition sources, as vapors can travel and accumulate in the surrounding air.
3 ft (914 mm) (A) and 5 ft (1,524 mm) (B) are insufficient to prevent ignition.
10 ft (3,048 mm) (C) may be acceptable for certain low-risk operations but does not meet the requirements for vehicle spray applications.
Reference:
NFPA 33, Section 9.3: Minimum distance from open flames and spark-producing equipment.
NEW QUESTION # 52
Which of the following conditions must be considered when determining the spacing and location of smoke detectors?
I . Ceiling height
II . Detector sensitivity
III . Ambient environment
IV . Ventilation or airflow
- A. I and IV
- B. II and III
- C. I, III, and IV
- D. I, II, III, and IV
Answer: D
Explanation:
The proper spacing and placement of smoke detectors are critical to their effectiveness. These factors are addressed in NFPA 72, National Fire Alarm and Signaling Code.
Ceiling height (I): Ceiling height affects smoke behavior. Higher ceilings allow smoke to cool and stratify, delaying detection. Adjustments must be made for ceilings greater than 10 feet.
Detector sensitivity (II): Smoke detector sensitivity determines how quickly it responds to smoke. Placement must account for conditions that may impact its performance.
Ambient environment (III): Environmental conditions such as temperature, humidity, and dust can affect smoke detector operation. Locations like kitchens or dusty areas may require specialized detectors.
Ventilation or airflow (IV): Airflow patterns created by HVAC systems, vents, or fans can direct smoke away from detectors, delaying activation. Proper placement ensures smoke reaches the detector efficiently.
Reference:
NFPA 72, Chapter 17: Detector spacing, location, and environmental considerations.
NEW QUESTION # 53
The fire resistance rating of a separation extending 10 ft (3050 mm) from a set of stairs shall not be required to exceed 1 hour where openings have a minimum of what fire protection rating?
- A. ½ hour
- B. 2 hour
- C. 1 hour
- D. 1 ½ hour
Answer: A
Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
Fire Resistance and Stair Separation:
According to NFPA 101 (Life Safety Code), Section 7.2.2.5, where a fire-rated separation extends 10 feet from a stair enclosure, the separation fire resistance does not need to exceed 1 hour if the openings have a ½-hour fire protection rating.
Why ½ Hour is Acceptable:
Openings with a ½-hour fire protection rating are sufficient to limit fire spread in lower-risk scenarios.
This exception applies to areas where the separation is minimal but still provides adequate protection to occupants using the stairway.
Other Options Explained:
Option A (2 hour): Not required for this scenario.
Option C (1 hour): The wall may be 1 hour, but the openings need only ½ hour.
Option D (1 ½ hour): Exceeds the requirements.
Summary:
Openings must have a minimum ½-hour fire protection rating where the fire resistance-rated separation extends 10 feet from a set of stairs.
NEW QUESTION # 54
When conducting a main drain test of a water-based fire protection system riser, what percentage of reduction in full flow pressure (as compared to the acceptance test or previously performed test) will trigger an investigation into the cause of the reduction?
- A. 3 percent
- B. 10 percent
- C. 2 percent
- D. 5 percent
Answer: D
Explanation:
A main drain test ensures that water flow and pressure in the system remain consistent. According to NFPA 25, Standard for the Inspection, Testing, and Maintenance of Water-Based Fire Protection Systems:
A 5 percent or greater reduction in full flow pressure compared to prior tests triggers an investigation to identify and correct potential issues (e.g., obstructions or valve malfunctions).
Reference:
NFPA 25, Section 13.2.5.2: Pressure reduction thresholds for main drain tests.
NEW QUESTION # 55
What is the maximum occupant load for a conference room with a total area of 900 ft² (84 m²)?
- A. 30 people
- B. 120 people
- C. 90 people
- D. 60 people
Answer: D
Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
Occupant Load Calculation:
According to NFPA 101 (Life Safety Code), Table 7.3.1.2, for assembly occupancies without fixed seating (such as conference rooms), the occupant load factor is:
15 ft² (1.4 m²) per person.
Calculation:
Divide the total area of 900 ft² by 15 ft per person: 900ft2/15ft2/person=60people900 , text{ft}
