Outside Ventilation Compliance | IMC Code for Nail Salons

IMC Code for nail salons

For new nail salons, IMC code requires a source capture system capable of exhausting a minimum of 50 CFM per station with exhaust inlets located not more than 12 inches from the point of chemical application.

The implementation of local exhaust ventilation systems using Source Capture technology is of utmost significance in nail salons. These systems play a crucial role in reducing potential health risks associated with airborne contaminants, such as ultra-fine particles and chemicals like acetone, isopropyl alcohol, and formaldehyde.

In order to ensure the well-being of both workers and customers, it is imperative to effectively remove fumes generated by these chemicals within the salon. Ventilation Code 403.3 mandates the installation of a source capture system at each manicure and pedicure station.

Nail Salon Sample Floor Plan

This floorplan features the Whisper MiniVent™ Source Capture System in both dual and single station configurations. With its compact size it can be easily placed between two stations, while still providing enough ventilation to meet IMC requirements.

Exhaust Flow & Placement

As per the definition of a source capture system, the exhaust from a station in a nail salon must capture air contaminants at their origin and expel them into the outdoor atmosphere. A minimum exhaust rate of 50 cubic feet per minute (cfm) is mandated at each station, with exhaust inlets positioned no more than 12 inches horizontally and vertically from the point of chemical application.

When one or more required source capture systems operate continuously during salon occupancy, the exhaust rate from these systems may be applied to meet the exhaust flow rate specified in Table 403.3.1.1 for the nail salon.

Moreover, in accordance with Section 501.3.1, the second clause of the International Mechanical Code (IMC), the endpoint for exhaust outlets releasing outdoors must be positioned at a distance of 10 feet from the property line, 3 feet from exterior walls and roofs, 10 feet away from accessible openings into buildings, and elevated 10 feet above the adjacent ground level.

The Aerovex Whisper™ Source Capture System and the new Aerovex Whisper MiniVent™ both meet IMC Code.
