An equipment component system including an equipment component structure having a first unit and a second unit and an intumescent paint or sealant on said equipment component structure. The intumescent paint or sealant provides sealing or prevents warpage or deformation or separation of a equipment component or sub-component in a fire or at high temperatures. The intumescent paint can shut a gap in a fire or at high temperatures. The intumescent paint can also pen a gap in a fire or at high temperatures so that fluid flow is preferentially directed one route versus another.
