What should be done if any measurement is below the specified thickness on an SFRM application?

When measuring the thickness of Spray-Applied Fire-Resistive Material (SFRM) applications, it is critical to adhere to specified thicknesses outlined in applicable codes and standards. If any measurement falls below the specified thickness, the application must be considered non-compliant with these requirements. This is essential because insufficient thickness can compromise the fire-resistive properties of the material, potentially resulting in structural failure during a fire event.

Classifying the application as non-compliant serves as an important safeguard in maintaining safety standards. It ensures that proper corrective actions can be taken, which may involve reapplication of the fireproofing material to achieve the required thickness and thereby ensure that the fire resistance is adequate for the intended use of the structure. By acknowledging the non-compliance, stakeholders can focus on fixing the issue rather than proceeding with a potentially unsafe application.
