Performing NFPA’s door safety inspections requires the individuals who perform this work to have a working knowledge of each type of door assembly they inspect, as well as the code requirements that affect them. Door Safety Inspectors (DSI) meet and exceed NFPA’s Qualified Person standard (for NFPA 80 and NFPA 105) and NFPA 101’s Knowledgeable Person standard to perform safety inspections and testing of egress and fire door assemblies.
