“Source capture ventilation” (SCV) is designed to capture salon chemical vapors and dusts at or near its source, protecting the technicians’ or stylists’ “Breathing Zone”, (which is an invisible two foot sphere in front of you and your client’s mouth from which we draw every breath). SCV also prevents dispersing of contaminants into the salon air.
When properly maintained and the carbon filters are changed regularly, SCV systems are a great way to help ensure salon air quality remains safe and everyone is breathing comfortably during working hours. Both dusts and vapors must be properly controlled. SVC systems do both, which is why I fully support their use in salons.
Nail techs who overexpose themselves to strong odors for long periods can develop a condition called “olfactory fatigue”, which means your nose/brain gets tired of smelling the strong odor, so the brain begins to ignore it. Then you can’t smell odors that others can smell easily. Eventually, this can begin to adversely affect your sense of taste, as well.”
“In the US, it is a legal requirement that salons must have proper ventilation because workers must be provided with a safe working environment. The necessary engineering controls to make this happen are required. Utilizing additional ventilation is always a good choice.”
The 2012 International Mechanical Building Code (IMC), states: Nail stations in nail salons must be provided with a source capture system capable of exhausting not less than 50 cubic-feet-per-minute.
“Use of ceiling fans, opening windows and air conditioning, although they do circulate air and will reduce concentrations of salon chemical vapors, mists and dust, are not proper salon ventilation control measures.”
Use of appropriate ventilation is necessary in the salon to control vapors and minimize the potential for “sensory irritation” and adverse health reactions. Salons that are not equipped with the appropriate ventilation needed to prevent sensory irritation should NOT provide these services until the situation is corrected. Proper ventilation that is appropriate for the services being performed is VERY important for both the client and salon professional. The best way to prevent clients’ and stylists’ overexposure to formaldehyde vapors is to use local source capture ventilation. As stated by the Professional Keratin Smoothing Council, www.pksc.org, in its, Oct. 2011 press release:
“Aerovex Systems, one of our founding members, is the developer of a hair salon source capture ventilation system, which provides a premiere example of “appropriate” salon ventilation equipment. Such equipment is useful for many types of salon services, including keratin hair smoothing, and can offer an extra layer of protection to help ensure the safety of clients and cosmetologists”.
