Mr. Havens - thank you for your comment! You highlight a very common issue. Existing installations, in many situations, not even just those involving fire doors, can present many challenges. I will bring your concern to the NFPA 80 committee at our next meeting.

Dwight Havens

It is appropriate that existing closures covered by NFPA 80 be inspected, tested and maintained, however, going back before 1993, there was not a specific requirement in the code. Further, there was no requirement that they be installed such that they could be inspected, tested and maintained. Building owners, who typically have no clue where the fire rated barriers in their buildings are, relied on the listing of the device to assure reliability. It is difficult to get architects and engineers who design today's buildings to recognize the need for access to these devices for inspection, testing and maintenance. Accessing existing closures in buildings that were never designed for such access can be practically impossible and extremely hazardous in many cases, yet the standard does not address this issue.
