When may acoustical and decorative materials such as cotton, hay, paper, straw, moss, split bamboo, and wood chips be used as decorations within an assembly occupancy?

D . When flame-retardant treated to the satisfaction of the AHJ

Answer: D

Explanation:

Acoustical and decorative materials pose a significant fire hazard due to their combustibility.

According to NFPA 101®, Life Safety Code®, Section 10.3.1, and related standards:

Such materials may only be used if they are flame-retardant treated or inherently noncombustible.

The treatment must be to the satisfaction of the Authority Having Jurisdiction (AHJ), ensuring compliance with testing requirements (e.g., NFPA 701).

Small quantities (B): Even small quantities can pose risks, so this is insufficient justification. Third-party certification (C): While helpful, AHJ approval is still required.
