Fire Rated Door Field Modifications

Date:Jul 02, 2019

Field modifications of a fire rated door require specific knowledge of the codes and should be performed by a person qualified to work on rated openings. NFPA 80 provides specific guidance on what can and cannot be done to a rated door. It is important to confirm that all new components have a label that matches the rating of the existing door and frame. In addition, the laboratory that initially approved the assembly must also approve the field modifications in writing per NFPA 80.
