What is the minimum net airflow in CFM per linear foot required for a single island canopy hood used for heavy-duty cooking?

• A. 500
• B. 600
• C. 700
• D. 800

Answer: (C)

The minimum net airflow required for a single island canopy hood used for heavy-duty cooking is indeed 700 CFM per linear foot. This specification is crucial due to the nature of heavy-duty cooking, which typically generates a significant amount of heat, smoke, and grease.

The 700 CFM per linear foot standard is in place to ensure that the ventilation system can effectively capture and remove these byproducts from the kitchen environment, maintaining air quality and safety. Adequate airflow is essential to comply with health and safety regulations, as well as to provide a comfortable working environment for kitchen staff.

This specific airflow requirement is set higher than those for standard cooking applications, reflecting the increased demands of heavy-duty equipment such as fryers, grills, and broilers that produce more emissions. In contrast, the lower airflow values associated with other options would not suffice to adequately ventilate spaces where heavy-duty cooking occurs, potentially leading to challenges in managing temperature, smoke, and odors effectively. Thus, 700 CFM per linear foot is the correct and effective standard for this context.
