Why a cooking fire leaves the kitchen
A fire that starts on the line or in the hood does not stop at the kitchen wall. Smoke and soot climb into the void over the suite, and on a retail pad whose attic or plenum runs from tenancy to tenancy they come down over the neighbours' stock. What lands there is grease-laden, and the method that takes dry soot off framing or paper will not shift it.
The hood system itself goes back to the company that services it. NFPA 96, the standard for ventilation control and fire protection of commercial cooking operations, covers cooking exhaust systems, stove exhaust hoods, grease removal devices and fire-suppression systems. That equipment is handled under it, by the owner's hood service company, before cooking resumes. Nothing in this scope covers that equipment or returns it to service.
The building around the equipment is what this work covers. Under ANSI/IICRC S700 the kitchen, the dining room and the ceiling space are cleaned in the standard's order: what cannot be cleaned comes out, the structure is cleaned, then the air paths that carried the smoke, then the contents that stay, and odor management follows all of it. Where a pad is shared, residue crosses a tenancy line that means nothing to smoke, so each suite is mapped and recorded on its own and each insurer sees its own part.
Opening a ceiling is demolition, whatever the reason for it. Grease residue in a ceiling space often means the material in it comes out, and in older retail blocks that material can hold asbestos. The structure is surveyed before anything is removed, the air district receives ten working days of notice, and regulated material is abated first, under the asbestos NESHAP.
What kitchen and hood fire cleanup includes
The kitchen is sealed from the dining room and from any part of the building still trading, cooking equipment and gas are left in the state the fire service handed over, and food, packaging and open stock are dealt with before cleaning starts rather than cleaned around.
The canopy, grease ducts, filters and suppression equipment are recorded in the file and passed to the owner's hood service company, which returns them to service under NFPA 96.
The void above the kitchen and the dining room is opened where the map calls for it, and material carrying grease residue is removed rather than cleaned in place.
Walls, ceilings, stainless, shelving, the backs and undersides of equipment and the floor finish are cleaned by the method the residue takes, working down from the highest surface. No surface is skipped.
Dining room ceilings, light fittings, upholstery and casework are cleaned or listed, because greasy smoke reaches the seating long before anyone notices it.
Where the ceiling space is shared, the suites either side are read and cleaned on their own records, so each tenancy has a scope of its own.
Grease-laden residue is not soot with a stronger smell. It behaves differently on every surface it lands on, and the method chosen for dry soot will spread it across a kitchen rather than take it off.
Where kitchen fires cause damage
Restaurant suites in pads
A single suite sits under a roof and a ceiling space shared with its neighbours, and the fire that starts on its line becomes their loss within minutes.
Shared ceiling spaces
Attics and plenums running across several tenancies carry grease residue above units that never smelled smoke on the floor below, until the ceiling is opened.
Hotel kitchens
A kitchen fire in an occupied building has to be contained from guest areas while the rest of the hotel keeps trading around it.
Dining rooms and bars
Booths, upholstery, ceiling tile and light fittings take up greasy smoke, and the smell in them outlasts the cleaning of the hard surfaces. Each is read on its own.
Staff canteens and break rooms
Cooking areas inside warehouses, plants and offices put a commercial kitchen fire inside a building that has nothing else like it. Containment there is built rather than assumed.
Older retail blocks
Layered ceilings and older materials above a kitchen are surveyed before any of them come down, which sets the order the rest of the work follows.
Questions about kitchen and hood fire cleanup
The hood service company, under NFPA 96, which reaches the canopy, the grease removal devices, the cooking exhaust and the suppression equipment. Everything outside that equipment is restoration work: the room it sits in, the space above the ceiling, the dining room beyond it, and whatever stock and fixtures stay where they are.
Each tenancy is mapped and recorded separately. Residue crosses a shared ceiling space without regard for the lease line, so the neighbouring suite gets its own readings, its own scope and its own photographic record, which is what the landlord and each insurer need to see. Residue does not respect a lease line.
No. It holds to surfaces differently and needs its own method, and using a dry-soot method on it spreads the film instead of removing it. The survey records which residue is where, so the method matches the surface it meets. The dwell time differs with it too.
Where the map shows residue in the void and the material has taken it up, yes, and that is demolition, so the asbestos survey and the air district notice come first. Regulated material is abated before anything comes down.
Once the building work is finished and the hood system has been returned to service by the company that maintains it. Both sides are recorded in the file, so the sequence is clear.
