What Is a Grease‑Related Inspection Failure?

Inspectors flag excess fats, oils, and grease (FOG) wherever they create contamination, slip/fall, ventilation, or fire hazards. Failures commonly show up in these zones:

• Exhaust hoods: Visible film, drip lines, heavy residue near open flame or heat sources.
• Ductwork (horizontal and vertical): Thick deposits at access panels, sludge in low spots.
• Exhaust fans and housings: Grease‑weighted blades, vibration, or weak airflow indicating restricted draw.
• Rooftops: Pooling grease, stained membranes, and missing or saturated containment pads.
• Baffle filters: Saturated, missing, warped, or improperly seated with active drips.
• Grease traps: Overfilled, strong odors, solids carryover, or backups during service.
• Floors, walls, and equipment: Slick traffic lanes, sticky equipment sides, splatter behind appliances.

Across Ontario, public health and fire authorities expect routine maintenance aligned to NFPA 96 for ventilation systems. Certified cleaning and clear documentation give you the strongest footing at re‑inspection. For certified help, review our NFPA 96 certified hood cleaning.

Why Grease Violations Matter

• Immediate closures: Significant grease buildup can prompt partial or full shutdowns until corrected.
• Fire risk: Grease‑loaded ducts can ignite and spread fire rapidly through the building.
• Air quality: Poor capture/containment increases smoke and heat, leading to staff fatigue and safety incidents.
• Plumbing impacts: Overfilled traps back up lines and contaminate prep or dish areas.
• Insurance & liability: Noncompliance can complicate claims and increase legal exposure.
• Public reputation: Inspection results affect reviews, guest confidence, and partnerships.

The reality is simple: sustained compliance lowers fire risk, stabilizes operations, and protects your brand. Ontario operators who standardize maintenance and documentation across sites see far fewer surprises during unannounced visits.

How Inspections Work—and Where Kitchens Slip

Inspectors rely on visual checks, wipe tests, and equipment performance to evaluate risk. Common trip‑ups include inconsistent SOPs, missing access panels, and thin documentation.

• Hood and duct checks: Edges, seams, and interior surfaces are inspected for film thickness and residue trails.
• Fan performance: Belt wear and grease‑weighted blades reduce draw and capture, prompting smoke‑line observations.
• Rooftop containment: Discharge without containment stains membranes and can trigger environmental concerns.
• Grease trap capacity: High FOG levels, odors, and backups indicate insufficient service frequency.
• Floors and equipment: Persistent films and splatter suggest daily cleaning gaps and training issues.

Re‑inspection success hinges on speed, scope, and proof. Combine certified exhaust and trap cleaning with photos, service reports, and updated SOPs. Our teams coordinate multi‑service visits—see our commercial kitchen hood cleaning service overview.

Types of Grease Problems & Fixes

Map symptoms to root causes, then apply the right mix of certified services and staff routines.

1) Exhaust System Problems

• Symptoms: Sticky hoods, smoky line, weak draw, rooftop stains, fan noise/vibration.
• Root causes: Irregular kitchen exhaust cleaning, limited access panels, worn or misaligned fan belts.
• Fixes: Full hood, duct, and fan cleaning; filter cleaning and exchange; fan belt replacement; rooftop grease containment installation. For certified support, see restaurant exhaust cleaning (GTA).

2) Filter Failures

• Symptoms: Sizzling drips, grease tracks, filters hot to the touch, visible warping.
• Root causes: Overextended cleaning intervals, improper seating, using non‑compatible filters.
• Fixes: Rotate filter cleaning and exchange sets; verify seating; replace damaged baffles; train staff on daily inspection.

3) Rooftop Discharge

• Symptoms: Grease pooling around the fan, stained membranes, odors drifting to patios.
• Root causes: Missing or saturated containment, duct leaks, poor fan housekeeping.
• Fixes: Install/refresh containment pads; deep‑clean fan housings; reseal joints; schedule quarterly rooftop checks.

4) Grease Trap Overload

• Symptoms: Odors, slow drains, visible solids, backups during service.
• Root causes: Extended pump‑out intervals; staff disposing of FOG down sinks.
• Fixes: Book grease trap service for pump‑out, scrape, and rinse; flush lines as needed; retrain for proper FOG handling. Explore grease trap cleaning services.

5) Equipment and Floors

• Symptoms: Slick traffic lanes, sticky equipment sides and backs, splatter behind cooklines.
• Root causes: Gaps in equipment cleaning, insufficient degreasing dwell time, missed detail behind/under units.
• Fixes: Commercial appliance cleaning, hot water power washing, detail work behind/under equipment, and refreshed daily SOPs.

72‑Hour Recovery Plan (Step‑by‑Step)

When “restaurant failed health inspection grease” is on the notice, move fast and document everything.

Time Window	Priority Actions	Proof for Re‑Inspection
0–24 hours	Stabilize: Pause lines creating most FOG; use lids and splash guards. Emergency filter exchange; wipe hot surfaces and hood ledges. Book NFPA 96 certified hood cleaning services (24/7 availability). Schedule grease trap cleaning if odors/backups exist.	Work order confirmations with timestamps. Photos of immediate controls (filters, ledges, floors).
24–48 hours	Full kitchen exhaust cleaning (hoods, ducts, fans, rooftop). Grease trap service with pump‑out, scrape, rinse; lines flushed as needed. Equipment cleaning of fryers, grills, ovens, and backsplashes. Set/refresh rooftop grease containment and reseal joints.	Before/after photos and service reports. Notes mapping work to NFPA 96 maintenance expectations.
48–72 hours	Replace worn fan belts; verify airflow with a draw/smoke test. Final wipe‑downs and detail cleaning behind/under equipment. Train staff on daily/weekly SOPs; launch logbooks and sign‑offs.	Maintenance checklists and staff training sign‑ins. Photos of clean access panels, fans, and filters.

Best Practices & Checklists

Systematize the work so it survives menu changes and staff turnover.

Daily Line‑Check Habits

• Inspect hood edges and ledges at open and close; wipe any visible residue.
• Confirm filters are seated tightly; replace if dripping or misshapen.
• Scrape pans into FOG bins before washing; never pour FOG into sinks.
• Spot mop with degreaser in traffic lanes; post wet floor signs.
• Record quick notes in the logbook (date, time, initials, issues).

Weekly Routine

• Rotate filter cleaning and exchange sets to maintain airflow.
• Degrease backsplashes, undersides of hoods, equipment sides, and casters.
• Empty and clean floor drains and screens; check trap room cleanliness.
• Check fan belts for wear and alignment; listen for vibration.
• Skim and inspect the grease trap for early warning signs.

Monthly/Quarterly Tasks

• Book restaurant exhaust cleaning per NFPA 96 frequency aligned to menu/volume.
• Audit rooftop containment and weather‑exposed seals.
• Refresh staff training; re‑post SOPs in back‑of‑house zones.
