OPERATIONS & REGULATIONS · FIRE RESPONSE
The fire is out. The fire department has left. The kitchen is a mess and the phone is ringing with reservations you can’t honor. The question every operator asks in that moment is “how fast can we reopen?” — and the honest answer is that four separate parties each have to sign off before the first burner lights, and the sequence matters more than the speed.

QUICK ANSWER
Reopening a commercial kitchen after a fire requires four sign-offs in a specific order: the fire marshal (or AHJ) must clear the incident investigation and confirm the exhaust system is safe to operate; the fire suppression vendor must inspect, recharge, and recertify the wet-chemical system; a Phil Ackland Certified or IKECA-credentialed exhaust cleaning vendor must clean the entire exhaust path to bare metal per NFPA 96 Section 12.6.5 and document it; and the insurance carrier must accept the claim documentation and authorize repairs. Depending on the fire’s severity and damage scope, realistic reopening timelines run from three to five days for a contained cookline incident to four to eight weeks for a fire that traveled the ductwork and damaged the roof. Operators with complete NFPA 96 documentation before the fire move through every step faster.

1. The First 24 Hours
What happens in the first day after a fire sets the tone for the entire reopening timeline. Four actions matter most.
- Do not touch the exhaust system. The fire marshal’s investigation determines cause, and the exhaust system is primary evidence. Cleaning, repairing, or even opening access panels before the investigation is complete can compromise the finding and complicate the insurance claim.
- Notify your insurance carrier immediately. Most policies require prompt notice — often within 24 to 72 hours. Late notice is a claim-denial ground in many policies. Call the claims line, get a claim number, and ask what documentation the adjuster will need.
- Pull your NFPA 96 documentation file. Service labels, access panel tag photos, written cleaning reports for the past 36 months, fire suppression testing certificates. The fire marshal and the adjuster will both ask for it. Having it ready on Day 1 changes the pace of everything that follows.
- Contact your exhaust cleaning vendor and suppression vendor. Not to start work — the fire marshal controls that — but to get on their schedule. Post-fire cleaning and suppression recharge are specialized visits, and vendors need lead time.
FIELD NOTE — THE INSTINCT TO FIX IT FAST
The strongest instinct after a fire is to start cleaning. Staff want to help. The owner wants to reopen. Someone grabs a degreaser and starts on the hood. Don’t. Until the fire marshal releases the scene, the exhaust system is evidence. Cleaning it before the investigation closes can shift the cause determination from “equipment failure” to “undetermined” — and an undetermined cause is much harder to defend at claim time. Wait for the release. It usually comes within 24 to 48 hours for a contained incident.
2. The Four Sign-Offs
Reopening requires clearance from four parties. They can overlap in time, but each has a dependency on the one before it, and none can be skipped.
SIGN-OFF
The Fire Marshal (AHJ)
The fire marshal’s investigation determines what caused the fire and whether the exhaust system contributed. The investigation typically produces a written report identifying cause, contributing factors, and any code deficiencies observed. That report becomes the reference document for every other party.
What the fire marshal checks:Â ignition source, fire path through the exhaust system, condition of the ductwork and access panels, hinge kit presence on the exhaust fan, service label currency, and the operator’s NFPA 96 documentation history.
What releases the scene: completion of the investigation and, in most jurisdictions, a written notice that cleaning and repair may proceed. If the fire marshal issues a deficiency notice alongside the release — missing access panels, absent hinge kit, overdue service — those items must be corrected before reopening. See our post on what happens after a failed fire marshal inspection for the correction sequence.
Timeline:Â 24 to 72 hours for a contained cookline incident. Longer for fires with injuries, structural damage, or a disputed cause.
SIGN-OFF 2
The Fire Suppression Vendor
If the wet-chemical suppression system discharged — and it should have — it’s empty. If it didn’t discharge, something failed, and the failure has to be diagnosed. Either way, the system needs a licensed suppression vendor before the kitchen can operate.
What the suppression vendor does:Â inspects the system for discharge damage or failure cause, replaces nozzles and fusible links as needed, recharges the wet-chemical cylinder, tests the manual pull and automatic detection, verifies the gas shutoff valve reset, and issues a recertification tag.
Dependency: the suppression vendor typically waits for the exhaust cleaning to finish before final testing, because discharge residue and fire debris in the hood interfere with nozzle inspection. Coordinate the two visits — cleaning first, suppression recertification second.
Timeline:Â one to three days from vendor arrival, assuming parts availability. Specialty nozzles or cylinder replacements can extend it.
SIGN-OFF 3
The Exhaust Cleaning Vendor
Post-fire exhaust cleaning is not routine service. Fire residue, carbonized grease, suppression chemical, and soot coat every interior surface from the hood to the rooftop. The system must be brought to bare metal per NFPA 96 Section 12.6.5 across the entire accessible path, and the vendor must assess whether any section is damaged beyond cleaning.
What the exhaust vendor does:Â cleans the hood, plenum, all ductwork through access panels, exhaust fan interior via the hinge kit, and rooftop discharge to bare metal; documents the condition of every section with photographs; identifies heat-damaged ductwork, warped access panels, failed duct seams, or compromised fan components that require repair or replacement before reopening; installs any access panels or hinge kits the fire marshal’s deficiency notice required; applies a new service label and access panel tags; and delivers a written report documenting the post-fire condition and the cleaning performed.
Dependency:Â fire marshal release. Nothing starts until the scene is cleared.
Timeline: one to two days for a single-hood system with no structural damage. Three to five days for multi-hood systems or systems requiring access panel or hinge kit installation. Longer if ductwork sections need replacement — that’s a mechanical contractor’s job, and the cleaning vendor coordinates the hand-off.
SIGN-OFF 4
The Insurance Carrier
The adjuster’s review runs in parallel with the other three sign-offs but controls the money. Repairs the carrier hasn’t authorized are repairs the operator may end up paying for.
What the adjuster does:Â reviews the fire marshal’s report, requests the operator’s NFPA 96 documentation history, compares the documentation against policy conditions, inspects or commissions an inspection of the damage, and issues a coverage determination and repair authorization.
The documentation test: this is where the pre-fire file matters most. Written reports showing compliant cadence, credentialed technicians, documented inspection findings, and tagged access panels move the claim forward. Gaps in any of those produce flags, and flags produce delays, reductions, or disputes. Our post on when insurance requires more than NFPA 96 covers the policy conditions that get tested at this stage.
Timeline:Â initial authorization for emergency cleaning and suppression recharge typically within three to seven days. Full repair authorization for structural or equipment replacement can run two to six weeks depending on claim complexity.
3. Realistic Reopening Timelines
Operators want a number. The number depends on how far the fire traveled and what it damaged.
| FIRE SCOPE | TYPICAL DAMAGE | REALISTIC REOPENING |
|---|---|---|
| Contained cookline flare-up | Suppression discharged; hood and filters coated; no duct involvement | 3 to 5 days |
| Plenum and horizontal duct involvement | Fire entered ductwork; heat damage to first duct section; access panels warped | 1 to 2 weeks |
| Full duct run to exhaust fan | Fan interior damaged; duct sections need replacement; roof curb heat-affected | 3 to 5 weeks |
| Rooftop and structural involvement | Roof membrane damage; fan replacement; possible structural repair; adjacent tenant impact | 4 to 8 weeks or longer |
Every row assumes the operator had complete NFPA 96 documentation before the fire and the fire marshal’s investigation found no code deficiencies. Add one to two weeks to each row for operators who need to correct deficiencies — install access panels, add hinge kits, establish a compliant cadence — before the AHJ will approve reopening.
THE VARIABLE CONTROL
The fire’s scope is determined by what happened. The reopening timeline is determined by what was already in place. Two identical fires at two identical restaurants reopen weeks apart when one has a complete documentation file and the other doesn’t. Our post on grease duct fires covers how the fire travels; this post covers what happens after it stops.
4. What Post-Fire Cleaning Actually Involves
Routine NFPA 96 service removes accumulated grease. Post-fire service removes grease, fire residue, suppression chemical, soot, and heat-damaged material — and assesses what can’t be cleaned.
Fire Residue and Carbonized Grease
Grease that burned leaves a hard carbon layer bonded to the metal. It doesn’t respond to standard degreasers. Post-fire cleaning uses more aggressive chemistry and more mechanical removal to bring the surface to bare metal per Section 12.6.5.
Suppression Chemical Residue
Wet-chemical agents (potassium-based solutions in Ansul R-102 and equivalents) are corrosive to some metals and leave a residue that must be neutralized and removed before the system is returned to service. Residue left in place accelerates corrosion and can affect fan bearings and motor components.
Heat Damage Assessment
Fire inside ductwork can warp panels, fail seams, and weaken the duct wall. The cleaning vendor inspects every accessible section and documents heat damage with photographs. Damaged sections are flagged for a mechanical contractor — cleaning vendors clean, they don’t fabricate ductwork. The hand-off is coordinated so the operator has one timeline, not two.
Exhaust Fan Evaluation
Fans that were running during a duct fire often have damaged wheels, failed bearings, or motor heat damage. The cleaning vendor opens the hinge kit, inspects the interior, and documents the condition. Our post on exhaust fan repair vs. replace covers the decision framework for damaged fans.
Rooftop and Containment
Fire that reaches the fan often reaches the roof. The cleaning vendor inspects the fan curb, the roof membrane around it, and the grease containment system for heat damage or contamination. Roof damage is a roofing contractor’s scope and a separate line on the insurance claim.
Deficiency Correction
If the fire marshal’s report identified missing access panels or an absent hinge kit, those items are installed during the post-fire visit — before the system can be cleaned to the standard, because you can’t clean what you can’t reach. See our post on the NFPA 96 access panel rule.
SIGNATURE APPROACH
From Cooktop to Rooftop, our Phil Ackland Certified Technicians bring the fire-damaged system back to bare metal, document every section with photographs, flag what needs a mechanical contractor, and deliver the written report the fire marshal and the adjuster both need. The outcome is a Grease-Free and Fire-Safe kitchen — recommissioned, not just cleaned.
5. The Documentation That Reopens the Kitchen
Four documents close the reopening process. Each one is produced by a different party, and the fire marshal typically wants all four before issuing final approval to resume cooking.
| DOCUMENT | ISSUED BY | WHAT IT CONFIRMS |
|---|---|---|
| Fire investigation report and scene release | Fire marshal / AHJ | Cause determined; system may be cleaned and repaired; any deficiencies listed |
| Suppression system recertification tag | Licensed suppression vendor | System recharged, tested, and ready for service |
| Post-fire written cleaning report with photos | Phil Ackland Certified exhaust vendor | System recharged, tested, and ready for service |
| Repair completion documentation | Mechanical / roofing contractor (if required) | Damaged ductwork, fan, or roof replaced or repaired to code |
With all four in hand, the operator requests a reopening inspection from the fire marshal. In most Southwest jurisdictions, that inspection happens within one to three business days of the request, and approval to resume cooking follows the same day if everything checks out.
6. After You Reopen
The fire changes the operator’s compliance profile for years. Three things shift.
Insurance
Expect enhanced review for at least three renewal cycles — tighter cadence conditions, longer documentation retention requirements, and a higher likelihood of loss-control site visits. Our post on insurance requirements beyond NFPA 96 covers what to expect.
Fire Marshal Attention
A kitchen with a fire on record typically sees more frequent AHJ inspection for the next several years. Keeping the documentation chain complete and current is the fastest way to move back into routine inspection rotation.
Service Cadence
Most operators tighten their NFPA 96 cadence after a fire — moving from semiannual to quarterly, or from quarterly to monthly — either because the insurance carrier requires it or because the fire made the fuel-load argument tangible. Our post on inspection vs. cleaning covers how to set the right cadence.
FIELD NOTE — THE SECOND FIRE
Kitchens that have had one fire are statistically more likely to have another — not because of bad luck, but because the conditions that produced the first one often persist. High-volume fryer operation, aggressive menu, tight margins that squeeze the maintenance budget. The operators who don’t have a second fire are the ones who treated the first as a compliance reset: new cadence, new vendor if the old one contributed, complete documentation from the day they reopened, and a standing relationship with the fire marshal built on transparency rather than avoidance.
Frequently Asked Questions
How long does it take to reopen a restaurant after a kitchen fire?
Three to five days for a contained cookline flare-up with no ductwork involvement. One to two weeks if the fire entered the plenum and horizontal duct. Three to five weeks if it reached the exhaust fan. Four to eight weeks or longer for rooftop or structural damage. Operators with complete NFPA 96 documentation before the fire move through every stage faster.
Who has to approve reopening after a kitchen fire?
Four parties: the fire marshal (investigation and scene release, then reopening inspection), the fire suppression vendor (system recharge and recertification), a certified exhaust cleaning vendor (full-system cleaning to bare metal with documentation), and the insurance carrier (claim acceptance and repair authorization). The fire marshal typically wants documentation from the other three before issuing final approval.
Can we clean the hood ourselves right after the fire?
No. The exhaust system is evidence until the fire marshal releases the scene. Cleaning before the investigation closes can compromise the cause determination and complicate the insurance claim. After release, NFPA 96 Section 12.6.1 requires the cleaning be performed by a properly trained, qualified, and certified person — post-fire cleaning is not a job for kitchen staff.
What does post-fire exhaust cleaning involve that routine cleaning doesn’t?
Removal of carbonized grease bonded to metal, neutralization and removal of wet-chemical suppression residue, heat-damage assessment of every accessible duct section, exhaust fan interior evaluation, rooftop and containment inspection, and correction of any deficiencies the fire marshal identified. Every section is documented with photographs.
Does the fire suppression system need to be replaced after it discharges?
Not usually replaced — recharged. A licensed suppression vendor inspects the system, replaces nozzles and fusible links as needed, recharges the wet-chemical cylinder, tests detection and manual pull, verifies gas shutoff reset, and issues a recertification tag. Full replacement is required only if the system failed to discharge and the failure can’t be repaired.
What documentation does the insurance adjuster want after a fire?
The fire marshal’s investigation report, the operator’s NFPA 96 documentation history (service labels, access panel tags, written cleaning reports for the past 24 to 36 months), fire suppression testing certificates, and the post-fire cleaning report. The adjuster compares this file against the policy’s conditions. Gaps produce flags; flags produce delays or disputes.
What if the fire marshal finds code deficiencies during the investigation?
The deficiencies — typically missing access panels, absent hinge kits, or overdue service — must be corrected before the fire marshal will approve reopening. The exhaust cleaning vendor installs panels and hinge kits during the post-fire visit. Deficiencies also appear in the fire marshal’s report, which the insurance adjuster reads.
Who repairs fire-damaged ductwork?
A mechanical contractor. Exhaust cleaning vendors clean and assess; they don’t fabricate or replace ductwork. The cleaning vendor documents heat damage with photographs and coordinates the hand-off so the operator has a single timeline. Roof damage is a roofing contractor’s scope.
Will my insurance premium go up after a kitchen fire?
Almost certainly. Expect enhanced underwriting review for at least three renewal cycles — tighter cadence conditions, longer documentation retention requirements, and more frequent loss-control site visits. Premium increases and coverage restrictions are common. Non-renewal is possible after significant claims or unresolved deficiencies.
How does Facilitec Southwest handle post-fire response?
Our Phil Ackland Certified Technicians coordinate with the fire marshal’s release, bring the entire exhaust path to bare metal, document every section with photographs, install any access panels or hinge kits the deficiency notice requires, flag heat-damaged sections for the mechanical contractor, coordinate with the suppression vendor’s schedule, and deliver the written report the fire marshal and adjuster both need. Service across TX, OK, LA, NM, and AR. See our Kitchen Hood Cleaning service.
