Most Edmonton restaurants are violating NFPA 96 without knowing it. This guide explains exactly what the standard requires, how your cooking type determines your cleaning schedule, and why your insurer will check your certificate the moment you make a fire claim.
Most Edmonton restaurant owners have heard "NFPA 96" — usually from their hood cleaning company, their insurance broker, or an inspector who mentioned it in passing. Few can tell you what it actually requires. Fewer still know whether they're meeting it.
NFPA 96 is the North American standard for commercial kitchen fire safety. It governs how often your exhaust hood system must be professionally cleaned, what that cleaning must cover, and what documentation proves it was done correctly. In Alberta, it is referenced in the National Building Code and enforced through fire inspections and insurance claims.
Here is what the standard actually says — in plain English, written for restaurant owners, not contractors.
The Four Cleaning Schedules Under NFPA 96
Your required interval is set by what you cook — not by preference or convenience
Solid-Fuel Cooking
Wood, charcoal, and mesquite grills — the strictest interval
High-Volume Frying
Quarterly — the most commonly missed requirement
Standard Restaurant Cooking
Most Edmonton restaurants fall here
Low-Volume Operations
The maximum allowed — cafés, low-heat kitchens
NFPA 96 — formally titled *Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations* — is published by the National Fire Protection Association. It has been the governing standard for commercial kitchen exhaust systems across North America since 1962 and is updated every three years.
In Alberta, NFPA 96 is adopted by reference into the Alberta Fire Code and the National Building Code of Canada. This means its requirements are not voluntary guidelines — they carry the force of law and are enforced by:
- Alberta fire inspectors — during scheduled and complaint-triggered inspections
- Insurance companies — when assessing claims involving kitchen fires
- Building inspectors — during occupancy and renovation approvals
- Your suppression system service provider — who cannot legally certify a system installed over a non-compliant exhaust setup
The standard covers every component of your commercial cooking exhaust system: the hood itself, the filters, the grease collection components, the ductwork running from the hood to the roof, and the rooftop exhaust fan. All of it. Not just the hood face your staff can see.
NFPA 96 does not set a universal cleaning schedule. Your required frequency is determined by what you cook and how much you cook it. This is the table directly from the standard:
Solid fuel cooking — Monthly
If your kitchen uses wood-burning equipment, charcoal grills, or mesquite fire, your exhaust system requires professional cleaning every single month. Solid fuels produce far more airborne grease and particulate than gas or electric equipment.
High-volume charbroiling or high-volume frying — Quarterly (every 3 months)
This applies to kitchens where the fryer or charbroiler runs for extended hours daily — high-volume burger operations, fried chicken concepts, BBQ restaurants. If your fryers run more than 4–6 hours per day, you almost certainly fall here.
Moderate-volume cooking — Every 6 months
This covers the majority of Edmonton restaurants: standard full-service kitchens with a mix of cooking methods, pubs, casual dining, and family restaurants. If you are unsure of your category, this is likely yours.
Low-volume or low-heat cooking — Annually (once per year)
Applicable to operations with limited or low-temperature cooking — some cafés, snack bars, and facilities with minimal grease-producing equipment. This is the maximum allowed interval under NFPA 96 for any commercial kitchen.
If your operation requires quarterly cleaning and you are on a six-month schedule, you are non-compliant for half of every year. Every day you operate outside the required interval, you are carrying a liability your insurance policy may not cover. See the insurance section below for what that means in practice.
A cleaning certificate you cannot produce is the same as a cleaning that never happened — at least as far as your insurer is concerned.
NFPA 96 uses "inspection" and "cleaning" to mean two different things. Confusing them is one of the most common compliance mistakes in the industry.
Inspection under NFPA 96 means a visual assessment of your exhaust system to determine whether cleaning is needed or whether grease buildup has reached a level that requires immediate action. An inspection does not clean anything. It is a diagnostic step.
Cleaning means the full removal of all grease deposits from the entire exhaust system — hood, duct, and rooftop fan. This is the service that produces a compliance certificate.
Why this matters for you:
Some lower-cost service providers offer "inspections" as their deliverable. They assess and report. They do not clean. If your hood has been "inspected" but not cleaned, your system is not NFPA 96 compliant and you have no valid certificate to show.
A compliant cleaning visit must:
- Remove all grease from every accessible interior surface of the hood, ductwork, and exhaust fan
- Be performed by a qualified technician with appropriate training and equipment
- Result in a written certificate documenting the date, scope of work, components cleaned, and technician name
- Note any areas that could not be accessed and recommend corrective action if found
Non-Compliant Service
NFPA 96 Compliant Service
A grease fire in a commercial kitchen is one of the most common and most expensive insurance claims in the food service industry. When you make a kitchen fire claim, your insurer does not take your word for anything. They investigate.
The first document they request is your cleaning certificate. They want to verify:
- That your exhaust system was professionally cleaned
- That the cleaning was performed within the required interval for your cooking type
- That the company who performed the cleaning was qualified to do so
- That documentation exists to support the service
If you cannot produce a current certificate, your insurer has grounds to deny the claim — or to reduce the payout — on the basis that you failed to maintain your equipment to the required standard.
This is not a theoretical risk. It is a standard clause in commercial restaurant insurance policies across Canada. The phrase you will see is something like *"the insured is required to maintain all cooking equipment in accordance with applicable codes and standards."* NFPA 96 is one of those standards.
What "current" means in this context:
A certificate is current if your last cleaning falls within the required interval for your cooking type. If you cook high-volume and your last cleaning was 7 months ago, your certificate is not current — even if it exists.
For information on what commercial insurance policies typically require, consult your broker directly and ask them to show you the maintenance conditions in your policy wording.
Do These Two Things Before You Continue Reading
1 — Find your most recent hood cleaning certificate right now. If you can't find it in under 2 minutes, that is the problem. 2 — Check what cooking type your kitchen falls under. If your fryers or charbroiler run for extended hours daily, you are likely required to clean quarterly — not annually.
Not every hood cleaning company delivers NFPA 96 compliant service. Some clean only the hood filters. Some clean the visible hood interior but skip the ductwork. Some issue a "receipt" rather than a compliance certificate. The checklist below gives you the exact questions to ask before hiring or re-hiring a hood cleaning company.
An NFPA 96 compliant hood cleaning service will answer every one of these questions without hesitation. If a company cannot answer them — or becomes vague — that is important information.
Ask every company you consider hiring. An NFPA 96 compliant provider answers all of these confidently.
If you are reading this and realizing your current service schedule does not match your cooking type, or your last certificate is older than it should be, here is the exact sequence to get back into compliance.
Look at the frequency table above. If you are charbroiling or frying at high volume, your interval is quarterly. If you are running a standard full-service kitchen, it is every 6 months. If unsure, default to 6 months — it is better to clean more frequently than to under-clean.
Find the most recent certificate your hood cleaning company issued. Check the date. Calculate whether it falls within your required interval. If the certificate is missing, expired, or doesn't exist — proceed immediately to Step 3.
Ask specifically: "Do you clean to NFPA 96 and provide a written certificate?" If the answer is vague, find another company. The certificate is the deliverable — the cleaning is how you earn it.
File it somewhere your manager can find it in under 60 seconds. Fire inspectors and insurance adjusters ask for it without warning. A certificate in a folder you can't locate quickly is nearly as useless as no certificate at all.
Put your next cleaning date in writing with your service provider and set a calendar reminder 30 days in advance. Non-compliance almost always happens by drift, not decision — the schedule gets pushed once, then again, and suddenly six months becomes fourteen.
What NFPA 96 Non-Compliance Actually Costs
The direct cost of a compliant hood cleaning is a few hundred dollars per visit. The cost of a denied insurance claim on a kitchen fire — the rebuild, the lost revenue during closure, the equipment replacement — routinely runs into the hundreds of thousands. NFPA 96 compliance is not an overhead expense. It is the condition under which your insurance policy is valid.
NFPA 96 is enforced in Alberta through the Alberta Fire Code, which adopts it by reference. Enforcement is carried out by local fire inspectors (under the authority of the provincial fire marshal), insurance adjusters during claims investigations, and building inspectors during occupancy and renovation approvals. The standard is not enforced by a single central body — it applies across multiple regulatory contexts.
It is legally binding. Because the Alberta Fire Code adopts NFPA 96 by reference, its requirements carry the force of law. Failing to meet the standard is not just an insurance risk — it is a code violation that can be cited during a fire inspection and result in a compliance order.
Your insurer will investigate the maintenance history of your exhaust system as part of the claims process. If you cannot demonstrate that your system was cleaned within the required NFPA 96 interval for your cooking type, the insurer has grounds to deny the claim or reduce the payout on the basis of failure to maintain equipment to the required code standard. This is a standard exclusion in commercial restaurant insurance policies.
The entire exhaust system — not just the hood. NFPA 96 requires cleaning of the hood, all grease collection components (drip trays, filters), the full ductwork from the hood to the exterior, and the rooftop exhaust fan. Companies that clean only the visible hood interior are not providing NFPA 96 compliant service, even if they issue a certificate.
NFPA 96 requires cleaning by qualified individuals with proper training and equipment. In practice, this means professional cleaning companies — not kitchen staff with degreasers and a pressure washer. Self-performed cleaning does not satisfy the standard, does not produce a valid compliance certificate, and will not hold up under insurer scrutiny.
A cleaning certificate documents that a full NFPA 96 compliant cleaning was performed — it is the record of service. An inspection report documents a visual assessment of the system's condition. You need both in sequence: an inspection can identify when cleaning is required, but only a cleaning produces the certificate that proves compliance. Some companies issue "inspection reports" and call it done — this is not compliant service.
There is no single mandated retention period, but best practice — and what insurers expect — is to keep the most recent three certificates at minimum. Given that inspection reports stay on the AHS public record for three years, keeping your cleaning records for the same period is a reasonable standard. Store them somewhere accessible — a folder in the office, not in the technician's truck.
Every ATA Hood Services cleaning is performed to full NFPA 96 standard — hood, ductwork, and rooftop fan. You receive a written compliance certificate after every visit, before-and-after photos, and a cleaning frequency recommendation based on your actual cooking type. One call books the service and closes the compliance gap.
