1. What Is NFPA 96?
NFPA 96 — formally titled Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations — is a standard published by the National Fire Protection Association (NFPA). It establishes the minimum requirements for the design, installation, operation, inspection, testing, and maintenance of all commercial cooking equipment and exhaust systems.
The standard covers every component of a commercial kitchen exhaust system, including:
- Cooking equipment (fryers, grills, broilers, woks, ovens)
- Exhaust hoods (Type I grease-rated and Type II heat/moisture)
- Grease filters and baffles
- Grease collection trays and drip cups
- Exhaust ducts and plenums
- Exhaust fans and motors
- Make-up air systems
- Fire suppression systems
NFPA 96 is updated on a regular cycle (typically every 3 years) and is the most widely adopted standard for commercial kitchen fire safety in North America.
2. NFPA 96 and the Alberta Fire Code
The Alberta Fire Code is the provincial regulation that governs fire safety for buildings and facilities in Alberta. It is published by the National Research Council of Canada and adopted by the Government of Alberta.
The Alberta Fire Code adopts NFPA 96 by reference as the applicable standard for commercial cooking ventilation and fire protection. This means that NFPA 96 requirements are legally enforceable in Alberta for all commercial food service establishments, including:
- Full-service restaurants and bars
- Fast food and quick-service restaurants
- Hotel and banquet kitchens
- Hospital and institutional cafeterias
- School and university food service
- Food trucks and mobile food units
- Catering facilities
- Any commercial kitchen producing grease-laden vapours
Key Point
Alberta fire inspectors from the Alberta Fire Commissioner's office and municipal fire departments enforce NFPA 96 compliance during routine inspections. Non-compliance can result in orders to cease operations until deficiencies are corrected.
3. Required Cleaning Frequency
NFPA 96 Table 11.4 specifies the minimum cleaning frequency for commercial kitchen exhaust systems based on the type and volume of cooking:
| Cooking Type / Volume | Minimum Frequency | Typical Operations |
|---|---|---|
| High-volume cooking | Monthly | 24-hour operations, solid fuel (wood/charcoal), wok cooking |
| Moderate-volume cooking | Quarterly | Most full-service restaurants, fast food, pubs |
| Low-volume cooking | Semi-annually | Seasonal businesses, day camps, churches with occasional cooking |
| Very low-volume cooking | Annually | Senior centres, churches, facilities with minimal cooking |
Important Note
These are minimum frequencies. If a qualified inspector determines that grease accumulation warrants more frequent cleaning, the schedule must be adjusted accordingly. Northern Hood and Exhaust will assess your specific operation and recommend the appropriate cleaning interval.
4. What Must Be Cleaned
NFPA 96 requires the entire exhaust system to be cleaned — not just the visible hood. The complete system includes:
Hood Canopy
Interior surfaces of the hood, including all corners, seams, and welds where grease accumulates.
Grease Filters & Baffles
All removable filters and baffles must be cleaned or replaced. Mesh filters are not NFPA 96 compliant.
Grease Collection Trays
Drip trays and grease collection cups must be emptied and cleaned at every service.
Exhaust Ducts
All accessible ductwork from the hood plenum to the rooftop exhaust outlet, including horizontal and vertical runs.
Exhaust Fan
Fan blades, housing, and motor housing must be cleaned of all grease accumulation.
Rooftop Components
The rooftop exhaust outlet, grease containment system, and fan housing exterior.
5. Inspection and Documentation Requirements
NFPA 96 Section 11.6 requires that after each cleaning, the contractor must provide a written report documenting:
- The date of service
- The name and certification of the cleaning contractor
- All areas of the system that were cleaned
- Any areas that were inaccessible and why
- The condition of the system before and after cleaning
- Any deficiencies found that require repair
- Recommendations for the next cleaning interval
This report must be kept on-site and made available to fire inspectors upon request. Northern Hood and Exhaust provides a comprehensive inspection report and compliance certificate after every service.
Pro Tip
Keep all cleaning reports in a dedicated binder near the kitchen. Fire inspectors will ask to see them, and your insurance company may request copies when renewing your policy or processing a claim.
6. Insurance Implications
Most commercial property and liability insurance policies for restaurants in Alberta include a condition requiring regular NFPA 96 compliant hood cleaning. Failure to maintain this cleaning schedule can have serious insurance consequences:
Claim Denial
If a grease fire occurs and you cannot provide documentation of regular cleaning, your insurer may deny the claim entirely — even if the fire was not directly caused by grease accumulation.
Policy Cancellation
Some insurers conduct periodic audits of commercial kitchen operations. Failure to maintain cleaning records can result in policy cancellation.
Premium Increases
A history of non-compliance or fire incidents related to grease accumulation can significantly increase your insurance premiums.
Personal Liability
If a fire causes injury or property damage to third parties and your insurance is voided due to non-compliance, you may face personal liability.
7. Penalties for Non-Compliance
Non-compliance with NFPA 96 and the Alberta Fire Code can result in serious consequences for restaurant operators:
- Compliance orders: Fire inspectors can issue orders requiring immediate corrective action.
- Closure orders: In cases of serious non-compliance or imminent fire hazard, inspectors can order the kitchen to cease operations until deficiencies are corrected.
- Fines: The Alberta Fire Code provides for fines for violations. Fines can be significant for commercial operations.
- Criminal liability: In cases where non-compliance contributes to a fire causing injury or death, operators may face criminal negligence charges.
- Business license issues: Municipal business licenses for food service operations may be revoked or not renewed if fire code compliance cannot be demonstrated.
8. Choosing a Qualified Contractor
NFPA 96 requires that kitchen exhaust cleaning be performed by qualified personnel. When selecting a contractor, look for:
IKECA Certification
The International Kitchen Exhaust Cleaning Association (IKECA) certifies contractors who meet rigorous training and competency standards.
NFPA 96 Knowledge
The contractor should be able to explain NFPA 96 requirements and how their service meets those standards.
Written Reports
A qualified contractor always provides a detailed written report after service — not just a sticker on the hood.
Insurance & WCB
The contractor should carry liability insurance and WCB coverage to protect your business.
References
Ask for references from other commercial kitchen operators in your area.
Before/After Photos
A reputable contractor will provide photographic documentation of the work performed.

9. Frequently Asked Questions
What does NFPA 96 require for kitchen hood cleaning in Alberta?
NFPA 96 requires that all commercial kitchen exhaust systems — including the hood, filters, grease traps, ducts, and fans — be inspected and cleaned at intervals based on cooking type and volume: monthly for high-volume or solid-fuel operations, quarterly for moderate-volume restaurants, semi-annually for low-volume operations, and annually for very low-volume facilities. The Alberta Fire Code adopts NFPA 96 as the applicable standard.
Is NFPA 96 compliance required by law in Alberta?
Yes. The Alberta Fire Code references NFPA 96 as the standard for commercial cooking ventilation and fire protection. Compliance is legally required for all commercial food service establishments in Alberta, including restaurants, cafeterias, food trucks, and institutional kitchens.
What is the difference between NFPA 96 and the Alberta Fire Code?
NFPA 96 is a national standard published by the National Fire Protection Association in the United States. The Alberta Fire Code is the provincial regulation that governs fire safety in Alberta. The Alberta Fire Code adopts NFPA 96 by reference, meaning NFPA 96 requirements are legally enforceable in Alberta. In some cases, Alberta may have additional or more stringent requirements.
How do I know if my contractor is NFPA 96 compliant?
A compliant contractor will provide a written inspection report after every service that documents all areas cleaned, any deficiencies found, and the contractor's certification. Look for IKECA certification as a mark of qualified contractors. The report should be detailed enough to satisfy a fire inspector or insurance auditor.
