Arizona health departments enforce comprehensive ventilation standards designed to protect public health and ensure safe food service operations. Understanding these requirements is essential for restaurant owners planning new installations or evaluating existing systems that may need upgrades to maintain compliance.

Exhaust Ventilation Standards

Commercial kitchen exhaust systems must remove cooking effluent at rates specified by local health codes, typically requiring 100-500 CFM per linear foot of cooking equipment depending on appliance type and cooking methods. Deep fryers, grills, and high-heat cooking equipment require higher exhaust rates to effectively capture grease vapors and combustion byproducts.

Health departments require that exhaust hoods extend beyond cooking equipment edges and maintain specific capture velocities to ensure effective contaminant removal. The National Fire Protection Association (NFPA) provides guidelines for hood sizing and placement that complement health code requirements while addressing fire safety concerns.

Grease removal efficiency is another critical compliance factor, with health codes requiring that exhaust systems remove at least 90% of grease particles before air is discharged outside. This protects both indoor air quality and prevents grease accumulation that could create fire hazards or attract pests.

Makeup Air Requirements

Arizona health codes require restaurants to provide adequate makeup air to replace air exhausted from kitchen areas. This makeup air must be conditioned to maintain comfortable working conditions and prevent negative pressure that could draw contaminated air from dining areas into kitchen spaces.

Makeup air systems must be sized to provide 80-100% of exhausted air volume while maintaining slight positive pressure in dining areas. This prevents odors and cooking fumes from reaching customer seating areas while ensuring adequate ventilation for safe food preparation. For businesses considering comprehensive system upgrades, our commercial HVAC installation services include specialized restaurant ventilation design that meets all regulatory requirements.

Fire Safety and Prevention

Restaurant kitchen ventilation systems must integrate with fire suppression systems to provide automatic shutdown capabilities during emergencies. Health codes require that exhaust fans shut down immediately when fire suppression systems activate, preventing the spread of flames through ductwork.
