What tool is approved by the building authority for determining the thickness of applied SFRM?

• A. Thickness meter
• B. Caliper
• C. Gauge
• D. Measuring tape

Answer: (C)

The gauge is recognized as the appropriate tool approved by building authorities for determining the thickness of applied Spray-On Fire-Resistive Materials (SFRM). This approval stems from the gauge's design, which allows for precise measurement, essential for ensuring compliance with fire safety standards. Gauges are specifically calibrated to assess the thickness of coatings, providing accurate readings that can be critical in applications where fire resistance is necessary. In contrast, while thickness meters and calipers can measure dimensions, they may not be specifically optimized or approved for evaluating SFRM thickness. Measuring tapes, though commonly used for general measurements, do not provide the level of precision required for assessing the thickness of fire-resistive materials. Therefore, the gauge stands out as the designated tool, aligning with the regulatory standards essential in construction and safety assessments.
