Discuss NFPA CFI-I Exam Topic 1 Question 24

In a new assembly occupancy, what is the maximum aggregate area of acoustical and decorative materials used on floor and wall areas the AHJ may approve?

A10 percent

B20 percent

C30 percent

D50 percent

Suggested Answer: B

Comprehensive and Detailed Step-by-Step Explanation:

Acoustical and Decorative Materials Limit:

According to NFPA 101 (Life Safety Code), Section 12.3.3.3, in new assembly occupancies, the maximum aggregate area of acoustical and decorative materials on floor and wall surfaces shall not exceed 20 percent of the surface area.

Why the 20% Limit Exists:

Decorative and acoustical materials can increase fire load and contribute to fire spread. Limiting their area ensures fire safety while accommodating aesthetics and functionality.

Other Options Explained:

Option A (10 percent): Too restrictive for the standard.

Option C (30 percent) and Option D (50 percent): Exceed the maximum allowed by NFPA 101.

Summary:

In a new assembly occupancy, the maximum aggregate area of acoustical and decorative materials allowed is 20 percent.
