NFPA 96 Hood Cleaning in Charlotte, NC

NFPA 96 — the Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations — is published by the National Fire Protection Association. It is widely referenced by fire officials and insurance carriers as the benchmark for how commercial kitchen exhaust systems should be built, operated, inspected and maintained.

It is worth being precise about what a cleaning company can and cannot claim here. A cleaning helps support compliance and helps keep a system inspection-ready. It does not certify a kitchen, and it does not guarantee an inspection result. Cleaning requirements depend on the specific system and cooking operation, and the final word belongs to your local authority having jurisdiction.

What the standard covers

• Construction and installation of hoods, ducts and exhaust fans
• Access openings so the full duct run can actually be inspected and cleaned
• Grease removal devices — the baffle filters over the cooking line
• Fire-suppression systems serving the cooking equipment
• Airflow and make-up air
• Inspection frequency for grease build-up, based on the type of cooking operation
• Cleaning of the entire grease-bearing surface, not selected sections
• Record keeping after inspection and cleaning

How inspection frequency is judged

The standard does not give every kitchen the same number. Frequency scales with the cooking operation: solid-fuel cooking is inspected most often, high-volume operations frequently, moderate-volume operations less often, and low-volume operations such as seasonal or day-camp kitchens least often. The practical test in a working kitchen is measured grease accumulation — if the system is loaded before the next scheduled date, the interval is wrong.

The frequency guide works through how cooking type, hours and equipment change the answer, and recurring hood cleaning is how the right interval gets held once it is established.

Cleaning the whole grease-bearing path

The distinction that matters most for inspection readiness is scope. Grease accumulates along the entire path, so the hood alone is never the job:

• Hood canopy, capture area and baffle filters
• The plenum behind the filters, where grease concentrates out of sight
• Horizontal and vertical duct runs, through access panels
• The exhaust fan, housing, blades and base
• Rooftop grease containment

Access panels are a compliance issue, not an upsell

A duct run without adequate access openings cannot be inspected or cleaned along its length. Older Charlotte buildings — converted mill space in NoDa and South End, long- established downtown kitchens in Gastonia and Rock Hill — are frequently under-panelled. Fitting proper access where the duct allows is what makes every later service both cheaper and genuinely complete.

Documentation and inspection readiness

What belongs in the record after every visit:

• Date of service and the systems covered
• Scope of work performed on each component
• Before-and-after photographs of the hood, duct interior and fan
• A written note of any section that could not be reached, and why
• A recommended next-service interval based on the grease load observed

Keep it on site. The record only helps when it is available at the moment the inspector, the insurance reviewer or a new manager asks for it.

Responsibilities that stay with the operator

• Daily and weekly maintenance between visits — see the maintenance routine
• Keeping filters in place, correctly oriented and undamaged during service
• Scheduling suppression-system inspection with a licensed suppression contractor
• Confirming required frequency with the local authority having jurisdiction
• Holding the cleaning records where they can be produced on request
