What is the primary purpose of installing an exhaust fan in a licensed salon?

The primary purpose of installing an exhaust fan in a licensed salon is to ensure proper ventilation. Adequate ventilation is crucial in a salon setting because it helps to remove airborne pollutants, including chemicals from products, odors, and excess heat that may accumulate during beauty treatments. This is particularly important in environments where various products that may produce fumes are used, such as dyes and chemical treatments.

Maintaining good air quality is essential not only for the comfort of clients but also for the health of both clients and staff. Proper ventilation decreases the risk of allergies and respiratory issues associated with inhaling harmful substances. By ensuring that stale air is replaced with fresh air, exhaust fans play a vital role in creating a safe and pleasant atmosphere in a salon. Other options, like controlling humidity levels or providing heating, while important for comfort, are not the primary function of exhaust fans in this context.
