Many “fixes” that I’ve seen on fire door assemblies are not compliant with NFPA 80 – Standard for Fire Doors and Other Opening Protectives. As fire door inspections increase, these problems will be noted, and must be repaired without delay.
Paul Goldense of Goldense Building Products came across this fire door assembly in a public school. Even if this jurisdiction is not yet enforcing annual fire door assembly inspections for schools, the school is required to keep their fire doors code-compliant and to repair them in a manner that is acceptable to NFPA 80.
If you’re responsible for the care and maintenance, installation, or repair of fire doors, make sure you are familiar with the requirements of NFPA 80. This Decoded article on Alterations to Fire Door Assemblies might be helpful for anyone performing job-site preparations and/or field modifications.
