In the case of CSP and intumescent systems, if they are not applied to the correct thickness across all surfaces of load-bearing steel members or panels/plates and there is a fire event, catastrophic collapse due to heat transfer to the steel can occur resulting in potential loss of life.

This month’s Case from the F-Files describes the problem of bubbles, pinholes, and blisters in a polyurethane finish coat applied to new structural steel members at a coal-fired power generation plant. Many of the pinholes and bubbles were so small that they were difficult to detect with the unaided eye. Many of the largest blisters
