NFPA 80: Fire Doors & Other Opening Protectives

Overview

NFPA 80 is the standard for fire doors and other opening protectives. It covers the installation and maintenance of the assemblies and devices that protect openings in fire-rated walls, floors and ceilings, in any type of building: swinging and rolling fire doors, fire shutters, fire windows, fire dampers and fire curtains, among others, and Chapter 5 adds the inspection and testing rules. Where the building code (IBC) sets the rating required by wall type, NFPA 80 sets the rules that keep that rated assembly performing as listed for the life of the building.

The headline requirement is the annual fire door inspection. Where your adopted fire code requires it, every fire door assembly is inspected and tested at least once a year, with a written record kept for the AHJ: the 2024 International Fire Code §705.2 requires opening protectives in fire-resistance-rated assemblies to be inspected and maintained under NFPA 80, and NFPA 80 sets the interval at not less than annually (§5.2.4.1). NFPA 101 §7.2.1.15 applies only where an occupancy chapter calls for it (healthcare chapters reach NFPA 80 through §8.3.3.1 instead), and allows intervals longer than 12 months under a written performance-based program. IBC §716 governs the construction side: required ratings, labeling, and closing behavior.

The current published edition is the 2025 edition, with the 2028 edition already in development. Enforced editions vary by jurisdiction — many states enforce the 2016, 2019, or 2022 editions through their adopted building and fire codes — and healthcare facilities under CMS jurisdiction follow the 2010 edition (referenced via the CMS-mandated 2012 edition of NFPA 101). Always confirm which edition your AHJ enforces. The full standard text is available through the NFPA free access page.

Who Is Responsible

NFPA 80's explanatory annex says a periodic inspection and maintenance program is generally the building owner's responsibility, and adopted codes make it a requirement: the 2024 International Property Maintenance Code §701.2, for example, requires the owner to provide and maintain fire safety facilities and equipment. The owner may hire out the work, but stays responsible for making sure inspections happen yearly, after installation, and after maintenance or repair.

Who can perform the inspection?

NFPA 80 itself does not require a specific certification. The standard says inspections must be performed by a "qualified person" — defined as someone who, by knowledge, training, and experience, has demonstrated the ability to evaluate fire door assemblies. Two certification programs are common examples of evidence of qualification:

• DHI CFDAI — Certified Fire & Egress Door Assembly Inspector, administered by the Door & Hardware Institute (in partnership with Intertek/Warnock Hersey)
• Intertek Qualified Personnel (IQP) fire door inspector — Intertek's qualified fire and egress door inspector program, open to students who have completed DHI's DAI 600 course

Some AHJs accept other paths to "qualified person" status (manufacturer training programs, locksmith certifications combined with fire-door training). Verify what your AHJ accepts before contracting an inspector — and look for proof of current certification on the inspector's deliverable.

Inspection cadence

• Annual inspection — at least once a year for each fire door assembly your adopted code covers (NFPA 80 §5.2.4.1). The annual requirement was added in the 2007 edition; many AHJs spent years catching up.
• After installation — the 2013 edition added a requirement that any newly installed fire door assembly be inspected before it goes into service.
• After maintenance or repair — NFPA 80 requires a fire door assembly to be inspected and tested as soon as any maintenance or repair work on it is finished, not only work on listed hardware (§5.5.9 in the 2019 edition, §5.5.10 in the 2022 and 2025 editions).
• Records — written, signed, and retained for AHJ review. Since the 2013 edition, §5.2.2.2 requires inspection and testing records be kept for at least 3 years (acceptance-test records for the life of the assembly, §5.2.2.1), on a medium that survives the retention period. Each record must identify the opening, the assembly, the inspector, and any deficiencies. Only the 2010-and-earlier editions (still governing CMS healthcare surveys) lack a numeric retention period.

The 13 Inspection Criteria

NFPA 80 lists the items a qualified person must check on every swinging fire door assembly during the annual inspection (§5.2.3.5.2 in the 2019 and 2022 editions, §5.2.3.6.2 in the 2025 edition). The inspection must be visual and from both sides of the door. The list grew from 11 items in the 2007 and 2010 editions to 13 items in the 2013 edition — which added label legibility as its own first item and signage compliance as the last — and has held at 13 in every edition since.

• Labels are clearly visible and legible.
• No open holes or breaks exist in surfaces of either the door or frame.
• Glazing, vision light frames, and glazing beads are intact and securely fastened in place, if so equipped.
• The door, frame, hinges, hardware, and noncombustible threshold are secured, aligned, and in working order with no visible signs of damage.
• No parts are missing or broken.
• Door clearances at the door edge to the frame, on the pull side of the door, do not exceed the standard's clearance limits (see Clearances section below).
• The self-closing device is operational — the active door completely closes when operated from the full open position.
• If a coordinator is installed, the inactive leaf closes before the active leaf.
• Latching hardware operates and secures the door when it is in the closed position.
• Auxiliary hardware items that interfere or prohibit operation are not installed on the door or frame.
• No field modifications to the door assembly have been performed that void the label.
• Meeting edge protection, gasketing, and edge seals (where required) are inspected to verify their presence and integrity.
• Signage affixed to the door meets the standard's signage rules (§4.1.4 in the 2019 edition, §4.1.3 in the 2022 edition, §4.1.6 in the 2025 edition). Signage became its own criterion in the 2013 edition; check the section number against the edition your AHJ enforces.

Failure of any item triggers a deficiency on the inspection report. The owner is responsible for correcting deficiencies promptly — and for re-inspection of any door whose hardware has been replaced or repaired.

Listed Labels

Fire doors, door frames and fire-rated glazing must carry a permanent label from an approved testing laboratory, and so must hardware that NFPA 80 requires to be labeled, such as closers, spring hinges, continuous hinges and fire exit hardware. Not every component carries a label: generic items such as plain steel butt hinges have none and must instead meet the standard's own specifications. Common testing laboratories: UL Solutions, Intertek (Warnock Hersey / WHI), FM Approvals, and ULC.

What the labels must show

Doors, frames and glazing each have their own label rules.

• Fire door (NFPA 80 §4.2.1; IBC §716.2.9.1): the words "fire door", the manufacturer's name or a code traceable to it, the certification agency's mark, the fire protection rating, a serial number if the listing agency issues one, the fire test standard, and the temperature rise at 30 minutes (which may be left off where it exceeds 650°F). Doors with builders hardware also show the minimum latch throw.
• Fire door frame (NFPA 80 §4.2.1.4): the words "fire door frame" (or "FDF" in the 2025 edition), the manufacturer, the certification agency's mark, the frame's rating and the test standard. Some frames need not show a rating, such as 3-hour frames with masonry anchors in masonry walls and 1-1/2-hour frames with stud anchors in gypsum walls, and a frame may instead carry an embossed agency mark and manufacturer code.
• Fire-rated glazing: a code marking from the building code's glazing tables (IBC Table 716.1(1); NFPA 80 §4.2.2), such as D-H-90 or W-120. D means it meets fire door criteria, H the hose stream test, T 450°F temperature rise for 30 minutes, W wall criteria, OH fire window criteria, and the number is the rating in minutes.

Swinging egress doors are tested to NFPA 252 (positive pressure) or UL 10C (IBC §716.2.1.1); access panels are commonly listed to UL 10B.

The label must be permanent (riveted, embossed, or equivalent), clearly visible, and legible throughout the life of the assembly. Painted-over, removed, or illegible labels are among the most commonly cited NFPA 80 deficiencies.

Field labeling (relabeling)

When a label is missing, painted over, illegible, or covered by replacement hardware (e.g., a continuous hinge that hides the original label), ask the door manufacturer and your AHJ about relabeling before replacing the door. The 2016 and 2022 editions allowed field labeling by certified or listed individuals or companies, or by representatives of a labeling service; the 2019 edition limited it to the listing agency (§5.1.4 in each); the 2025 edition removed the field-labeling provisions. Where the 2024 International Fire Code applies, the fire code official may approve field-applied labels that follow the requirements of the third-party certification organization that lists the door (IFC §705.2.1). A building owner, contractor or inspector cannot simply apply a new label.

Relabeling is for a sound door whose label was lost or obscured. If the door has been altered beyond what its listing allows, a new label does not fix it: ask the manufacturer to take the change to its listing laboratory, which may authorize it in writing or, where the manufacturer is no longer in business, provide an engineering evaluation (§5.1.4.1 in the 2025 edition, §5.1.5 in the 2019 and 2022 editions). If the change cannot be brought within the listing, the door or the affected part must be replaced.

Field Modifications

Field modifications that void the listing are inspection criterion 11 — and routinely appear on inspectors' published deficiency lists. The general rule: modifications must be authorized by the door manufacturer's listing AND, where hardware is involved, the hardware manufacturer's listing. When in doubt, contact the door manufacturer.

The 1-inch hole rule

Round holes drilled in the field for hardware preparation are limited to 1 inch (25.4 mm) maximum diameter, with two exceptions. The cylinder-hole exception predates the 2016 edition; the surface-applied hardware exception was added in 2016:

• Cylinder holes may be any diameter required to accommodate the cylinder.
• Holes exceeding 1 inch in diameter are permitted for surface-applied hardware (door closers, surface-mounted exit devices, magnetic locks, etc.) where installed in accordance with both the door manufacturer's listing AND the hardware manufacturer's listing.

The dual-listing requirement is the catch: the larger hole is permitted only where the installation follows both the door manufacturer's listing and the hardware manufacturer's listing (§5.1.4.2.2.3 in the 2025 edition). Two products that are each listed do not qualify on that alone; check that each listing covers this installation.

Filling unused holes

Fastener holes left in a door or frame from removed hardware or plant-ons must be filled per NFPA 80 §5.5.7 (clarified in the 2016 edition). Any other hole is a field modification and follows those rules instead. Acceptable methods for fastener holes:

• Steel fasteners that completely fill the hole
• Filling with the same material as the door or frame (steel weld for hollow metal, listed wood plug for wood doors)
• Filling with a material listed for this use, installed per the manufacturer's procedures

Other field-modification rules

• Adding glazing — vision-panel glazing must go in a labeled glass light kit or follow the fire door's listing (§4.4.4.1 in the 2025 edition). For new wood doors, glazing is installed under the door's listing and label service, and the 2025 edition also allows field glazing of a labeled metal-frame vision light kit, installed per the kit maker's instructions, where the light cutout was machined under label service (§4.4.4.3 and §4.4.4.4). Cutting a new opening into an existing door is a field modification that needs the listing laboratory's authorization through the manufacturer. Earlier editions did not allow field glazing of new wood doors.
• Undercutting (trimming the bottom) — NFPA 80 allows up to 3/4 inch (19 mm) of job-site undercut on wood and composite doors (§5.1.4.2.2 in the 2025 edition). That is a limit on trimming, not the finished gap: the clearance under the installed door must still not exceed 3/4 inch unless the listing allows otherwise (§4.8.4.1), and many listings allow less.
• Trimming the top or width — generally NOT permitted as a field modification on most listings.
• Repairing damage — a damaged door, frame or part must be repaired with listed or labeled parts or parts from the original manufacturer, or retrofitted as an authorized field modification; if neither is possible, the damaged part or door must be replaced (§5.5.5 and §5.5.6 in the 2022 edition). Body filler is not an NFPA 80 repair method; follow the door manufacturer's own repair instructions for dents. Fastener holes left from removed hardware are a separate case, covered by the three methods above (§5.5.7).

Hardware Compliance

Hardware on a fire door must be suitable for fire door use. Closers (listed and labeled to UL 228 under §6.4.1.2 in the 2025 edition), spring and continuous hinges, latches and locks, and fire exit hardware must be listed or labeled for fire doors, while plain steel ball-bearing hinges are generic items that must meet NFPA 80's hinge rules in §6.4. Those rules reference ANSI/BHMA standards for the underlying hardware tests.

Self-closing devices

Swinging fire doors must latch, and must be either self-closing or automatic-closing (IBC §716.2.6.1; NFPA 80 §6.1.5). The IBC exempts a few doors, such as fire doors in common walls between Group R-1 dwelling or sleeping units. Either way, the closer must be adjusted so the door fully closes and positively latches when released from the full open position; that is the field test in inspection criterion 7. A door that closes but doesn't latch fails inspection, and so does one that stops short.

When spring hinges serve as the closing device, NFPA 80 requires them to be adjusted so the door positively latches when it is allowed to close freely from an open position of no more than 30 degrees (§6.4.1.5 in the 2022 edition, §6.4.1.6 in the 2025 edition).

For choosing a closer, see the door closer selection guide and our ANSI/BHMA A156.4 door closers page. Closers are in our surface door closers collection; check each closer's listing for fire door use.

Hinges

• All hinges and pivots must be ball-bearing type, except spring hinges. Hinges or pivots with other antifriction bearing surfaces are permitted if they meet ANSI/BHMA A156.1 (hinges) or, since the 2025 edition, ANSI/BHMA A156.4 (pivots) (§6.4.3.1.5.1).
• Doors up to 60 inches in height require a minimum of 2 hinges. One additional hinge for each additional 30 inches of door height (or fraction thereof). A 90-inch door takes 3 hinges; a 100-inch door takes 4.
• Spring hinges, when used, must be labeled to ANSI/BHMA A156.17 Grade 1.
• Continuous (gear / pin-and-barrel) hinges are permitted where listed for fire-door use; a continuous hinge that covers the original door label triggers a relabeling question for the manufacturer and AHJ.

Butt hinges are in our butt hinges collection. Choose hinges by base material, not finish. Hager, for one, says steel and stainless steel hinges may be used on fire-rated or labeled openings but brass hinges may not, because of brass's low melting point, and it plates steel and brass hinges to the same finishes. Check the hinge's base material and model against the maker's fire door guidance.

Latching

• Positive latching is required when the door is in the closed position. The minimum latch throw is established by the door manufacturer's listing (typically 1/2 to 3/4 inch) and appears on the fire door label.
• Recent editions of NFPA 80 dropped the body-text numeric throw requirement and defer to the listing. Older editions specified throws directly.
• Mortise locks, cylindrical locks, and mortise/rim panic devices are all permitted when listed for fire-door use.

Panic hardware on fire doors (fire exit hardware)

Panic hardware on a fire door is a specific category called fire exit hardware. The IBC requires it to be listed to both UL 305 (panic hardware) and UL 10C (positive-pressure fire test) (§1010.2.9.3 in the 2021 IBC, §1010.2.8.3 in the 2024 IBC), and NFPA 80 requires it to be labeled as fire exit hardware for both fire and panic use. Standard panic hardware listed only to UL 305 is not permitted on a fire door. NFPA 252 is a test for the door assembly, not the hardware: the door itself is tested to NFPA 252 (positive pressure) or UL 10C (IBC §716.2.1.1).

• Fire exit hardware must be labeled as fire exit hardware — both panic and fire test listings on the device label.
• Mechanical dogging is prohibited on fire exit hardware. Dogging holds the latch retracted, defeating the self-latching requirement.
• Electric latch retraction (ELR) is permitted on fire exit hardware where the installation is fail-safe (NFPA 80 §6.4.4.3.3): a fire alarm contact cuts power on alarm so the latch projects automatically, and any power loss does the same.

Exit devices are in our rim exit devices and vertical rod exit devices collections; on a fire door, choose a device labeled as fire exit hardware. Our ANSI/BHMA A156.3 page covers the exit device standard.

Coordinators on pairs

A coordinator is required on pairs where the closing sequence matters — an overlapping astragal, or automatic/constant-latching flush bolts on the inactive leaf. It holds the active leaf open momentarily while the inactive leaf closes first; inactive-before-active is inspection criterion 8. Pairs with vertical-rod fire exit hardware on both leaves normally need no coordinator, since either leaf can close and latch independently.

Automatic flush bolts (top and bottom) are typical on the inactive leaf. Manual flush bolts require AHJ acceptance and must present no life-safety hazard (the section number differs by edition); the annex guidance points them at doors to normally unoccupied spaces such as transformer vaults and storage rooms. Flush bolts are in our flush bolts and strikes collection.

Hold-open devices

Wedges, doorstops, kickdown holders, chains, and any non-listed device used to hold a fire door open are violations of NFPA 80. Compliant hold-opens are listed automatic-closing arrangements: a separate electromagnetic holder released by the fire alarm system, or a closer-holder unit with an integral smoke detector. Either way the model codes (IBC §716.2.6.6, NFPA 101 §7.2.1.8) require release on smoke detection or power loss — which is why fusible-link hold-opens, though still recognized in NFPA 80's automatic-closing definition, are rarely acceptable in practice: a fusible link responds to heat, not smoke.

Clearances

NFPA 80 sets maximum gap dimensions between the door and frame. In the 2013 through 2022 editions, perimeter and meeting-edge clearances are in §6.3.1.7; the 2025 edition moved them to §6.3.1.8 and loosened one category. Bottom clearances are in §4.8.4 in every one of these editions. Confirm the limits against the edition your AHJ enforces. Inspection criterion 6 verifies that gaps are within these limits on the pull side of the door. Gaps exceeding the limits compromise the assembly's ability to resist fire and smoke spread — and the tolerance cuts both ways: a gap tighter than the allowance can bind the door and defeat self-closing.

The 2025 edition explicitly allows listed fire door accessories that close excessive clearances, at the head, jambs and meeting edges (§6.3.1.8.3) and under the door (§4.8.4.3). NGP's GapGuard accessories are made for that job on an existing fire door, without replacing it. NGP states they are UL certified, with the gap range, door type and rating set out for each product. The door's listing and your AHJ decide whether a repair is accepted.

Rolling Fire Doors

Rolling steel fire doors (overhead coiling fire doors) follow NFPA 80's rolling-door inspection rules — Chapter 5 sections distinct from the swinging- door criteria. The headline test is the annual drop test.

Drop test

• Frequency: annually.
• Procedure: drop the door TWICE — once to verify proper operation and full closure, then a second time after reset to verify the automatic-closing device was correctly reset.
• Closing speed: average closing speed must NOT exceed 24 inches per second AND must be at least 6 inches per second. A door closing too slowly fails to close before fire/smoke breach; too fast risks injury and damage.
• Reset: the release mechanism must be reset per the manufacturer's instructions. Since the 2022 edition, drop tests and resets are performed by a "trained rolling steel fire door systems technician" — someone with documented training and experience on these assemblies; the training can come from manufacturers, vendors, or in-house resources acceptable to the AHJ (wording confirmed for the 2025 edition by TIA 25-1).

Inspection items

• Slats, endlocks, bottom bar, guide assembly, curtain entry, hood, and flame baffle correctly installed and intact
• Curtain, barrel, and guides aligned, level, plumb, and true
• Expansion clearance per the manufacturer's listing
• Drop-release arms and weights not blocked or wedged
• Mounting and assembly bolts intact and secured
• Smoke detectors (if equipped) operational
• Fusible links (if equipped) in correct location, chains/cables not kinked, links not painted or coated

Access Panels in Rated Walls

Fire door assemblies include more than swinging corridor doors. When a rated wall or barrier needs a maintenance opening — for valves, dampers, cleanouts, or junction boxes — the access panel covering that opening is an opening protective, and it must carry its own fire listing. An unrated panel cut into a rated wall defeats the barrier at that point, the same way an unrated door would.

Fire-rated access panels (also called fire-rated access doors) are commonly listed for 1-1/2 hours in vertical/wall installations, to the neutral-pressure ANSI/UL 10B and CAN/ULC-S104 tests; verify the test standards on the specific panel's label and submittal. Swinging egress doors instead need the positive-pressure UL 10C test. Like any fire door, they must be self-closing and self-latching — a listed panel has a closer that closes and latches the door from the open position, and holding one open defeats the listing the same way a wedged corridor door does. Ceiling (horizontal) installations follow different rules: rated floor/ceiling and roof/ceiling assemblies are tested as horizontal assemblies (ASTM E119/UL 263, under the IBC's horizontal assembly provisions in §712), so wall listings do not transfer. Ceiling ratings are assembly-dependent and size-limited; check the panel's label for its specific ceiling listing.

IBC Table 716.1(2) shows a minimum 1-1/2-hour opening protective for a 2-hour wall (not a 2-hour panel), which is why 1-1/2-hour ("B"-label) panels are the common choice for 2-hour wall openings; lower-rated walls can carry different minimums, and the wall type and AHJ control. Access panels in rated assemblies are also subject to NFPA 80 inspection and maintenance under their listing and the standard's applicable provisions (IFC §705.2 requires opening protectives in rated assemblies to be inspected and maintained per NFPA 80), and they are easy to miss because they don't look like doors. The label rules from the Listed Labels section apply unchanged: a painted-over label on an access panel is the same deficiency as one on a corridor door.

Choosing a configuration

Rated panels are built in a few flange configurations so the same listed door and frame can finish cleanly into different wall types:

Order size equals door size, and the clear opening runs smaller — verify the rough opening against the specific model's submittal before cutting. Our access panels collection carries both fire-rated and general-purpose panels; only a labeled, fire-rated panel belongs in a rated wall.

Smoke Doors & NFPA 105

NFPA 80 covers FIRE doors. NFPA 105 (Standard for Smoke Door Assemblies and Other Opening Protectives) covers SMOKE doors. The two are commonly enforced together because a door in a smoke barrier is often also a fire door: the 2024 International Fire Code §705.2 requires opening protectives in smoke barriers to be inspected and maintained under both NFPA 80 and NFPA 105. NFPA 105 has its own inspection and testing criteria (§5.2 in the 2025 edition).

UL 1784 air-leakage test

Smoke door assemblies are tested to UL 1784. To bear the "S" label (Smoke and Draft Control), the assembly must achieve air leakage of NOT MORE THAN 3.0 cfm/ft² of door opening at 0.10 inch water column, tested at both ambient and 400°F. NFPA 80 itself does not reference UL 1784 — gasketing is required on a fire door only when that door is also required to function as a smoke door (typically per IBC §716 or NFPA 101).

Pairs of smoke doors

Pairs of smoke doors need gasketing at the meeting edges where the door's listing requires it, installed to form a continuous seal across the top, the vertical edges and the meeting edges (NFPA 105-2025 §6.7.1). Any astragal must be part of the listed assembly, and pairs in a means of egress must not use an astragal that keeps either leaf from being used freely (§6.7.2). Gasketing must be labeled and installed in accordance with the gasketing manufacturer's listing; choose a product listed for the door it goes on.

For the leakage test itself, see our UL 1784 smoke seals page; for choosing perimeter and meeting-stile seals, the fire door gasketing guide. Gasketing, sweeps and door bottoms are in our door seals and gasketing collection; check each product's listing against the door's label.

Edition Timeline

NFPA 80 has been on a roughly 3-year revision cycle. The major changes worth knowing:

Enforced editions vary by jurisdiction. Many states enforce the 2016, 2019, or 2022 editions through their adopted building and fire codes. The 2024 IBC and IFC reference the 2022 edition of NFPA 80 (so does NFPA 1-2024), so adopting the latest I-codes does not by itself bring in the 2025 edition; a jurisdiction gets the 2025 edition only by adopting it directly or through a later code edition that references it. Healthcare under CMS jurisdiction effectively follows the 2010 edition because CMS adopts the 2012 NFPA 101 and has not moved forward — which matters in practice: the 2010 edition permits only two fastener-hole repair methods, not the listed-filler option added in 2016. The 2028 edition is in development on the Annual 2027 cycle.
