CFI Plan Review & Permitting 3 — Questions and Answers
Question 1: When reviewing plans for an underground fire main connecting a building to the public water supply, which NFPA standard primarily applies?
- NFPA 24 (Correct answer)
- NFPA 13
- NFPA 20
- NFPA 291
Correct answer: NFPA 24
NFPA 24 covers the installation of private fire service mains and their appurtenances, including underground piping.
Question 2: A plan review reveals that a new tenant finish in a covered mall has exit signs spaced 100 feet apart along a corridor with no intervening turns. What is the concern?
- Exit signs must be illuminated with green light in malls
- Exit signs must be visible from any point and 100-foot spacing may exceed the line-of-sight requirement (Correct answer)
- The number of exit signs is excessive for a mall tenant space
- Covered malls are exempt from exit sign requirements under NFPA 101
Correct answer: Exit signs must be visible from any point and 100-foot spacing may exceed the line-of-sight requirement
NFPA 101 requires exit signs to be visible from any point in the egress path; spacing that exceeds line-of-sight distances requires additional signs.
Question 3: Which of the following is NOT typically included in a complete fire protection system plan submittal?
- Hydraulic calculation sheets
- Equipment cut sheets and listing information
- Contractor's business tax returns (Correct answer)
- Site plan showing water supply connection
Correct answer: Contractor's business tax returns
Financial documents such as tax returns are not part of a fire protection system plan submittal; technical documents, calculations, and equipment data are required.
Question 4: A fire inspector is reviewing plans for a building that will store flammable liquids in quantities exceeding the maximum allowable amounts. What is required?
- A variance from the state fire marshal is always required
- The building must be classified as an H occupancy with appropriate construction and protection (Correct answer)
- Excess quantities must be stored off-site with no exceptions
- A written waiver signed by the building owner is sufficient
Correct answer: The building must be classified as an H occupancy with appropriate construction and protection
Quantities exceeding the maximum allowable amounts (MAQ) require the space to be classified as a High-Hazard (Group H) occupancy with specific construction and fire protection requirements.
Question 5: During plan review for an addition to an existing sprinklered building, the inspector notices the existing system was designed under a previous code edition. What should the inspector evaluate?
- Whether the addition creates a material change that requires upgrading the entire system (Correct answer)
- Whether the previous code edition can be applied to the entire project without review
- Whether the existing system must be completely replaced regardless of the addition size
- Whether the sprinkler contractor holds a current license only
Correct answer: Whether the addition creates a material change that requires upgrading the entire system
When an addition or change-of-use creates a material change in hazard or demand, the AHJ must determine if the existing system requires modification to maintain compliance.
Question 6: A permit application for a temporary membrane structure seating 500 people requires fire inspector review. Which document most directly governs this structure's fire safety requirements?
- NFPA 102 (Correct answer)
- NFPA 13D
- NFPA 58
- NFPA 1142
Correct answer: NFPA 102
NFPA 102 covers grandstands, folding and telescopic seating, tents, and membrane structures, making it directly applicable to temporary tent and membrane structure assemblies.
Question 7: What is the primary purpose of requiring as-built drawings to be submitted after completion of a fire protection system installation?
- To allow the fire inspector to bill for additional plan review time
- To provide accurate documentation for future inspection, maintenance, and modifications (Correct answer)
- To replace the approved construction documents in the permit file
- To satisfy insurance underwriter requirements only
Correct answer: To provide accurate documentation for future inspection, maintenance, and modifications
As-built drawings document the system as actually installed, which is critical for future inspections, maintenance activities, and any subsequent modifications.
