The provided documents outline the 2023 Florida Mechanical Code specifically regarding ventilation and exhaust standards for personal care businesses such as barber shops, beauty salons, and nail salons. These regulations mandate specific outdoor airflow rates and occupant densities to ensure air quality within the breathing zone of each facility. A significant focus is placed on nail salons, which require source capture systems at every workstation to remove chemical vapours at the point of application. These systems must operate continuously during occupancy and maintain a minimum exhaust rate of 50 CFM per station. The materials include both the technical legal requirements and a study guide featuring quizzes and glossaries to help professionals understand and implement these safety protocols.
