What is the maximum column flange width permitted when applying SFRM?

• A. 18 inches.
• B. 16 inches.
• C. 12 inches.
• D. 14 inches.

Answer: (B)

The maximum column flange width permitted for the application of Spray-Applied Fire-Resistive Material (SFRM) is 16 inches. This specification is critical in ensuring effective fire protection and maintaining the integrity of the structural steel during a fire event. Column flanges that exceed this width may pose challenges for achieving uniform coverage of the fire-resistant material, which could lead to spots where protection is inadequate. Since SFRM must adhere properly and provide consistent depth to effectively insulate the steel against high temperatures, there are established guidelines to limit the flange width for optimal performance. Maintaining appropriate flange dimensions is part of a broader strategy to ensure that structures comply with fire safety regulations, thereby reducing risks during emergencies and ensuring the protection of both lives and properties.
