NFPA 96 sets the standards for ventilation control and fire protection in commercial cooking operations. Compliance with these standards is often mandatory and essential for legal operation.

We emphasize the importance of following NFPA 96 guidelines for cleaning intervals. The standard requires that hoods, grease removal devices, fans, ducts, and other components be cleaned before surfaces become heavily contaminated with grease or oily sludge.

Regular inspections and cleanings, performed by certified professionals, ensure ongoing compliance. This helps avoid potential fines or penalties and maintains good standing with local fire marshals and health inspectors.

Proper documentation of cleanings and inspections is crucial. It provides proof of compliance and can be valuable for insurance purposes in case of a fire incident.

Assessing the Kitchen Exhaust System

A thorough assessment of the kitchen exhaust system is crucial for maintaining safety and compliance. We’ll examine the key components, identify grease accumulation, and evaluate cleaning schedules to ensure optimal performance.

Components of the Exhaust System

The kitchen exhaust system consists of several critical parts. We start with the hood, which captures smoke, grease, and vapors above cooking equipment. Filters inside the hood trap larger grease particles. Ductwork carries the exhaust from the hood to the exterior. The fan, typically located on the roof, provides the necessary airflow.

We inspect each component carefully. The hood should be free from visible grease and properly positioned over cooking surfaces. Filters must be clean and securely in place. We check ductwork for any signs of leaks or damage.

Identifying Grease Buildup

Grease accumulation is a significant fire hazard in kitchen exhaust systems. We look for visible grease on all surfaces, paying special attention to areas prone to buildup. Hood interiors often show the first signs of grease deposits.

We use depth gauges to measure grease thickness in ductwork. Any accumulation exceeding 1/8 inch requires immediate cleaning. Horizontal duct runs and corners are hotspots for grease collection. We also inspect the fan housing and blades for grease buildup.

Evaluating the Cleaning Schedule

The cleaning frequency depends on the volume and type of cooking. We review the current cleaning schedule and compare it to industry standards. High-volume operations or those using solid fuels may require monthly cleanings.

We examine cleaning logs to ensure consistency. Signs of excessive grease between scheduled cleanings indicate a need for more frequent service. We also consider any changes in kitchen operations that might affect the cleaning schedule.

Regular assessments help maintain a safe and efficient kitchen exhaust system. By staying vigilant, we can prevent fire hazards and ensure compliance with safety regulations.
