Lesson 1Assembly verification: interpreting labels, cross-referencing manufacturer’s listing, and documenting missing or altered labelsDis guide dey lead learners through verifying di complete assembly by interpreting labels, cross-checking manufacturer listings, and documenting missing or altered labels wey fit invalidate di fire door rating.
Reading and decoding label dataUsing manufacturer listings and guidesConfirming component compatibilityRecognizing field-altered assembliesDocumenting nonlisted substitutionsLesson 2Hardware inspection: closers, latches, strike plates, pivots, self-closing devices, coordinated hardwareDis dey address systematic hardware inspection, including closers, latches, strikes, pivots, and coordinated devices, ensuring dat all components function together to provide reliable self-closing and latching.
Verifying self-closing device operationInspecting latches, strikes, and throwsChecking hinges, pivots, and bearingsCoordinators and sequential closing needsIdentifying missing or disabled hardwareLesson 3Frame and stop inspection: mounting, continuous stops, gaps, and warpingDis dey detail inspection of frames and stops, including anchorage, alignment, continuity of stops, and gap conditions, helping inspectors detect warping, loose frames, and other issues wey compromise fire door performance.
Verifying frame anchorage and plumbChecking continuous stops and profilesMeasuring frame-to-door gap uniformityIdentifying frame twist, bow, and warpAssessing shims, grout, and fastenersLesson 4Operational testing procedures: latch/close tests, hold-open devices, closer adjustment checks, and smoke test basicsDis dey outline operational testing procedures for fire doors, including latch and closing tests, hold-open device checks, closer adjustments, and basic smoke tests to confirm reliable, code-compliant performance.
Standard latch and closing test stepsTesting hold-open and release devicesEvaluating closer speed and latching forceBasic field smoke test techniquesRecording and interpreting test resultsLesson 5Exterior process and sample selection: order of inspection and rationale for sampling 12 doorsDis dey describe how to plan di exterior inspection process, set an efficient door order, and apply sampling logic, including when and why a 12-door sample may be used and when full-population inspection is required.
Mapping inspection routes and sequencesSelecting representative sample doorsRationale for a 12-door sample sizeWhen full inventory inspection is neededRecording sample selection justificationLesson 6Glazing, louvers, and vision panels: labels, glass type, stops, and backing materialsDis dey cover inspection of glazing, louvers, and vision panels, focusing on label verification, glass type, mounting details, and backing materials so learners fit identify unsafe field modifications and noncompliant components.
Required fire and safety glazing labelsIdentifying approved fire-rated glass typesStops, beads, and glazing channel detailsLouvers and vision panel size limitationsBacking materials and fire-resistance ratingsLesson 7Door leaf inspection: construction, clearances, edge conditions, damage assessmentDis dey explain how to inspect di door leaf for construction type, edge integrity, clearances, and visible damage, enabling accurate assessment of whether di leaf still meet its fire and smoke performance requirements.
Identifying door core and facing materialsMeasuring perimeter and undercut clearancesEvaluating edge seals and edge integrityRecognizing field modifications and repairsDocumenting impact, moisture, and heat damageLesson 8Signage and certification labels: location, legibility, required markingsDis dey explain how to inspect signage and certification labels, confirming their presence, location, legibility, and required markings so dat each door assembly fit be properly identified and verified in di field.
Required fire door label informationApproved label locations on assembliesAssessing label legibility and damageSignage content and mounting criteriaHandling missing or painted-over labelsLesson 9Thresholds and undercuts: sills, gaps to floor, and smoke control relevanceDis dey focus on thresholds and undercuts, including sill types, floor conditions, and smoke control needs, so inspectors fit judge whether gaps and components comply with fire and smoke door requirements.
Types of thresholds and sill assembliesMeasuring undercut and floor clearanceSmoke and draft control gap criteriaEvaluating uneven or sloped floor surfacesField solutions for excessive undercutsLesson 10Gasketing and smoke seals: types, location, compression, gaps, and replacement criteriaDis dey cover gasketing and smoke seals, including types, locations, compression, and wear, enabling inspectors to determine when seals are missing, damaged, incorrectly installed, or require replacement to maintain performance.
