ICC 86 SFRM Inspector case studies
ICC 86 SFRM Inspector · Put your knowledge to work in context.
The ICC 86 SFRM Inspector credential is a certification for people who verify spray-applied fire-resistive materials on structural steel. SFRM is the wet- or dry-mixed coating sprayed onto beams, columns, and decking to buy time before steel reaches the temperature at which it loses strength. The inspector's job is to confirm that what was specified is what was installed: correct material, correct substrate preparation, correct thickness and density, adequate adhesion, and a paper trail that survives an authority having jurisdiction review. Candidates typically come from third-party inspection firms, general contractors, fireproofing applicators, special inspection agencies, and structural engineering support roles. The ICC 86 SFRM Inspector case studies are 5 cases and about 2,735 words.
