Which of the following best describes the purpose of exhaust fans in cooking areas?

The purpose of exhaust fans in cooking areas is primarily to remove heat and moisture produced during cooking. When food is cooked, it generates heat and steam, which can create an uncomfortable environment and contribute to an increase in humidity levels. The exhaust fan helps to expel this heat and moisture, ensuring that the kitchen remains a comfortable and safe space for food preparation.

Additionally, effectively removing heat and moisture can also prevent issues like mold growth or damage to kitchen surfaces that could occur with excessive humidity. While there are aspects of air circulation, odor filtration, and lighting that can be involved in a cooking environment, the key function of exhaust fans is their ability to eliminate unwanted heat and moisture, making the cooking process safer and more pleasant.
