If a salon lacks an exhaust system, what must be kept on during business hours?

In a salon that lacks an exhaust system, keeping the thermostat fan switch on during business hours is critical for maintaining air quality and ensuring proper circulation. The fan assists in moving air throughout the space, which can help prevent the buildup of fumes and vapors from products used during procedures like eyelash extensions. This is especially important in a beauty salon, where various chemical products may be in use.

By having the thermostat fan switch activated, you create a more comfortable environment for clients and staff, as it helps to mitigate potentially harmful odors and airborne particles. Proper air circulation can also contribute to temperature regulation within the salon, enhancing the overall experience for everyone present.

While heating and ventilation, air conditioning, and lighting are important for a salon's operation, they do not specifically address the critical need for air circulation in the absence of an exhaust system as effectively as the thermostat fan switch does. The fan essentially serves to refresh the air in the salon, which is crucial for health and comfort.
