What is the best practice if the SFRM surface is determined to be uneven?

When the surface of Spray-Applied Fire-Resistive Material (SFRM) is found to be uneven, the most effective course of action is to reposition the gauge to a flatter section. This practice allows for accurate readings and assessments of the fire-resistive material's thickness and integrity, which are critical for ensuring structural safety and compliance with fire protection standards. If the gauge remains positioned on an uneven area, it may produce misleading results that could compromise the evaluation of the fireproofing application.

Having a consistent and even test area is essential for obtaining reliable data. By relocating to a flatter section, the testing can reflect the true condition of the SFRM, allowing for proper analysis and necessary remediation steps if the thickness does not meet the specified requirements. This method ensures that the integrity of the fireproofing is maintained and enhances the overall safety of the structure in question.

The other options do not directly contribute to accurate testing or resolution of the issue at hand. Reporting the issue without taking steps to validate or test further does not address the underlying problem. Similarly, shifting to another testing location without first attempting to adjust for the unevenness misses an opportunity to gather useful data in the current area.
