If the SFRM is cured and too hard, how should holes be made for thickness measurement?

• A. Large holes
• B. Wide holes
• C. Small-diameter holes
• D. Medium holes

Answer: (C)

When the Spray-applied Fire Resistant Material (SFRM) is cured and has hardened, making small-diameter holes is the recommended approach for thickness measurement. This method minimizes the impact on the overall integrity of the SFRM while providing accurate measurement points. Small-diameter holes ensure that there is less disruption to the material, reducing any potential weakening of the protective layer that SFRM provides. Furthermore, this technique allows for precise access to the area being measured without unnecessarily compromising larger sections of the material or affecting the bonding and performance characteristics of the SFRM. Accurate thickness measurements are vital for ensuring compliance with safety and building code requirements, and using smaller holes achieves this while maintaining the structural integrity of the fire-resistant coating.
