FPE Building Codes & Standards 2 — Questions and Answers
Question 1: Under IBC, which occupancy group classification applies to a building used as an ambulatory surgical center?
- Group B
- Group I-2 (Correct answer)
- Group I-1
- Group A-3
Correct answer: Group I-2
IBC classifies ambulatory surgical centers as Group I-2 because they house patients incapable of self-preservation under anesthesia.
Question 2: NFPA 101 defines a 'horizontal exit' as a way of passage from one area of a building to another area on approximately the same level separated by a fire barrier with a minimum fire resistance rating of:
- 1 hour
- 2 hours (Correct answer)
- 3 hours
- 4 hours
Correct answer: 2 hours
NFPA 101 requires horizontal exits to be separated by a 2-hour fire barrier to provide refuge without descending stairs.
Question 3: Which IBC section governs the allowable area increases for buildings provided with an automatic sprinkler system throughout?
- Section 503
- Section 504
- Section 506 (Correct answer)
- Section 508
Correct answer: Section 506
IBC Section 506 addresses allowable building area modifications, including increases granted for sprinkler protection.
Question 4: According to NFPA 13, what is the minimum distance a standard spray sprinkler head must be installed from a wall in a light hazard occupancy?
- 2 inches
- 4 inches (Correct answer)
- 6 inches
- 12 inches
Correct answer: 4 inches
NFPA 13 requires standard spray sprinklers to be located at least 4 inches from walls to ensure effective discharge patterns.
Question 5: In the IBC, a Type III-B construction building is characterized by:
- Non-combustible exterior walls and any interior elements
- Combustible exterior walls and non-combustible interior structure
- Non-combustible exterior walls and combustible interior elements with no fire resistance (Correct answer)
- Fully combustible construction with no fire resistance requirements
Correct answer: Non-combustible exterior walls and combustible interior elements with no fire resistance
IBC Type III-B has non-combustible exterior walls but allows combustible interior structural elements with no fire-resistance rating requirement.
Question 6: NFPA 72 requires that audible fire alarm notification appliances in sleeping areas produce a sound level of at least:
- 55 dB(A)
- 65 dB(A)
- 75 dB(A) (Correct answer)
- 85 dB(A)
Correct answer: 75 dB(A)
NFPA 72 mandates a minimum of 75 dB(A) at pillow level in sleeping areas to reliably wake occupants.
Question 7: Under IBC, which of the following is NOT a factor used to determine the required fire resistance rating of an exterior wall?
- Distance to property line
- Occupancy group
- Building height in stories (Correct answer)
- Fire separation distance
Correct answer: Building height in stories
IBC exterior wall fire resistance ratings are determined by occupancy group and fire separation distance, not building height in stories.
