NFPA 96
What Is NFPA 96 and Why Does It Apply to Your Kitchen?
NFPA 96 — the National Fire Protection Association Standard for Ventilation Control and Fire Protection of Commercial Cooking Operations — is the governing standard for commercial kitchen exhaust systems across the United States. It sets minimum requirements for the design, installation, operation, inspection, and maintenance of kitchen exhaust systems, including how often hood cleaning must occur.
NFPA 96 is enforced by local fire marshals and adopted by building codes in all 50 states. Failure to comply can result in failed inspections, fines, forced closures, and voided insurance coverage.
Key fact: NFPA 96 does not require a specific cleaning company — it requires cleaning to a documented standard. A cleaning service that does not provide before-and-after photos and a signed CASR (Cleaning and Accessibility Service Report) is not performing NFPA 96-compliant work, regardless of what they claim.
Cleaning Frequency
How Often Is Hood Cleaning Required?
NFPA 96 Section 11.4 specifies cleaning frequency based on cooking type and volume. The table below reflects the current standard. Note that local fire marshals may require more frequent cleaning — they cannot require less.
| Cooking Type / Operation | Required Frequency | Examples |
|---|
| High-volume cooking with solid fuel | Monthly | Wood-fired grills, charcoal cooking |
| High-volume charbroiling or wok cooking | Monthly | Steakhouses, Asian restaurants with wok stations |
| Moderate-volume cooking, standard operations | Quarterly | Full-service restaurants, casual dining |
| Low-volume cooking | Semi-annually | Pizza, sandwiches, light frying |
| Seasonal or very low-use | Annually | Seasonal operations, concession stands |
⚠️ Important: The cleaning frequency in your CASR report must match your actual cooking operations. A steakhouse claiming annual cleaning frequency will fail a fire marshal inspection. Your service provider should assess your cooking type and recommend the correct frequency in writing.
Documentation
What Documentation Is Required After Every Hood Cleaning?
NFPA 96 Section 11.6 requires specific documentation after every hood cleaning. This documentation must be kept on-site and produced on demand during fire marshal inspections.
Required CASR Elements
- Date of service
- Name and contact information of the cleaning company
- Technician name and certification information
- Scope of work performed (which components were cleaned)
- Areas that were inaccessible and why
- Before-and-after photographs of hood, duct, and fan
- Technician signature and date
- Next recommended cleaning date based on cooking type
TruShine standard: Every TruShine service includes a complete CASR report with before-and-after photos uploaded to your digital compliance file within 24 hours of service completion.
NFPA 17A
Fire Suppression System Requirements
NFPA 17A — the Standard for Wet Chemical Extinguishing Systems — governs commercial kitchen fire suppression systems. Semi-annual inspection is mandatory for all commercial cooking operations that use an automatic fire suppression system.
| Requirement | Standard | Frequency |
|---|
| Full system inspection | NFPA 17A | Every 6 months |
| Agent level verification | NFPA 17A | Every 6 months |
| Fusible link replacement | NFPA 17A | Every 6 months |
| Nozzle inspection | NFPA 17A | Every 6 months |
| Full system inspection after discharge | NFPA 17A | Before reopening |
| Inspection after equipment change | NFPA 17A | Immediately |
⚠️ Insurance risk: Many commercial property insurance policies require documented semi-annual fire suppression inspections. A system that has not been inspected within 6 months may void your coverage in the event of a kitchen fire — even if the fire was unrelated to the suppression system.
FOG Regulations
Grease Trap and FOG (Fats, Oils & Grease) Compliance
Grease trap compliance is governed by EPA FOG regulations and local sewer authority ordinances. Requirements vary by municipality but all commercial food service operators with grease-producing operations are required to maintain properly functioning grease traps or interceptors.
Why FOG Compliance Matters
A grease trap that overflows or fails inspection results in: EPA fines (up to $25,000 per day per violation), sewer authority fines, forced closure pending compliance, and personal liability for sewer system damage.
| Operation Type | Recommended Frequency | Standard |
|---|
| Full-service restaurant, high volume | Monthly | EPA / Local FOG ordinance |
| Fast casual, moderate volume | Every 60–90 days | EPA / Local FOG ordinance |
| Low-volume café or deli | Quarterly | EPA / Local FOG ordinance |
| Seasonal operation | Per season | EPA / Local FOG ordinance |
Inspection Prep
Commercial Kitchen Health Inspection Checklist
Health inspectors evaluate commercial kitchens across multiple categories. This checklist covers the most commonly cited violations. Print it and walk your kitchen before your next inspection.
Hood & Exhaust System
- Hood cleaning CASR report on-site and within compliance window
- Filters clean and properly seated — no visible grease drips
- Grease collection cup emptied and clean
- No visible grease accumulation on hood surfaces
- Exhaust fan operational and properly venting
- Fire suppression inspection within last 6 months
- Suppression system nozzles unobstructed
Grease Management
- Grease trap pumping manifest current and on-site
- No evidence of grease backup or overflow
- Grease trap covers accessible and properly sealed
- No grease pooling on floors near fryers or cooking line
General Kitchen
- All equipment surfaces clean and free of grease buildup
- Fryers clean — no carbonized buildup on baskets or walls
- Floor drains clean and flowing properly
- Walk-in cooler and freezer clean, temperatures within range
- All food stored off floor, properly labeled and dated
- Pest activity — no evidence of rodents or insects
Common Violations
The 7 Most Common Commercial Kitchen Compliance Violations
These are the violations that lead to failed inspections, fines, and forced closures most often. All are preventable with a proper maintenance program.
01
Missing or outdated hood cleaning documentation
The #1 reason for hood-related violations. The hood may be clean but without a CASR report on-site, it fails inspection. Fix: ensure your cleaning provider delivers documentation the same day as service.
02
Fire suppression system overdue for inspection
NFPA 17A requires inspection every 6 months. Many operators lose track of the inspection date. Fix: calendar both inspection dates on the first visit, and use a vendor who sends reminders.
03
Cleaning frequency doesn't match cooking operations
A restaurant doing high-volume charbroiling with quarterly cleaning documentation will fail. NFPA 96 requires monthly cleaning for that cooking type. Fix: have your cleaning provider assess cooking type and assign the correct frequency in writing.
04
Grease trap pumping records missing or expired
FOG manifest records must be kept on-site. Many operators lose track of pump records when they switch vendors. Fix: consolidate grease trap service under the same vendor as your hood cleaning and request consolidated documentation.
05
Grease on filters, plenums, or ducts above the hood
Many budget cleaning services only clean what's visible. NFPA 96 requires cleaning the entire exhaust system including ducts and rooftop fan. Fix: use only IKECA-certified providers who document the full system clean.
06
Suppression nozzles blocked or misaligned after equipment change
NFPA 17A requires a full inspection after any change to kitchen equipment. Moving a fryer or adding a cooking station requires realignment and re-certification. Fix: notify your suppression service provider before any equipment change.
07
No before-and-after photos in cleaning record
A signed service report without photos does not meet NFPA 96 documentation standards in most jurisdictions. Fire marshals increasingly require photo evidence. Fix: require photos from every cleaning service and confirm they're in your file before the technician leaves.
