Fire-rated gypsum panel product systems may be damaged during the life cycle of a building. To maintain the required fire-rated separation between occupancies or areas, damaged systems must be repaired so that they are restored to their original fire-resistive condition. The repair must follow procedures dictated by the severity of the damage.
Small holes (such as those caused by a door knob) can be repaired by patching. An example of a damaged gypsum panel is shown in Figure 1.
