David is a licensed professional engineer in Pennsylvania and a credentialed Fire Door Assembly Inspector (FDAI).
The Formative Years:
David’s interest – and passion – for fire door assemblies began in 1997, a decade before fire door inspection requirements were expanded into a new chapter – and given new emphasis – in NFPA 80 -2007.
Prior to 1997, fire door components (doors, frames, and builders door hardware) were laboratory tested by Underwriters Laboratories according to Standard UL-10B (Standard for Fire Tests of Door Assemblies).
In 1997, Standard UL-10C (Standard for Positive Pressure Fire Tests of Door Assemblies) was introduced to define the latest testing requirements for fire door components. This new standard reflected actual conditions observed by fire fighters.
At the time, David was developing a new door control product line for a commercial door hardware manufacturer. The door control design was modified to comply with the requirements of UL-10C, preventing the device from spreading fire to the non-fire side of the door. At the time, this was “cutting edge” (i.e., the latest technology).
During testing of fire doors and hardware per the UL-10C standard, David observed that door failure was common if any component (door, frame, or hardware) was improperly installed to the utmost detail. It became apparent that not only was initial installation critical, but proper maintenance of the fire door assembly was crucial if the fire door assembly was to perform as intended during an actual fire.
Fire door maintenance has always been identified in NFPA 80 (Standard for Fire Doors and Other Opening Protectives). Prior to 2007, fire door maintenance was a single sentence, “Hardware shall be examined frequently and any parts found to be inoperative shall be replaced immediately” (Paragraph 16-2.1.1). However, proper maintenance was given new emphasis with the addition of a new, expanded maintenance chapter in NFPA 80 -2007, Chapter 5 – Care and Maintenance.
In 2008, the year after NFPA 80 was revised to include the new maintenance requirements in Chapter 5, David completed certification to become a certified fire door inspector. From 2008-2012, David was Product Manager for a manufacturer of door hardware products. While designing and testing hardware, the UL10C fire door testing requirements and NFPA 80-2007 annual inspection criteria and requirements always played an important role in the development process.
In 2014, David completed the more intensive and comprehensive training and testing required to become a certified Fire Door Assembly Inspector (FDAI) through the Door and Hardware Institute (DHI) and Intertek. Since 2014, David has combined his fire door inspection credential and field product specialist role to help architects, specification writers, distributors, and facility personnel understand and properly specify, apply, install, and maintain commercial door hardware, especially fire door hardware.
