The news media did not differentiate between data that was obtained for automated spray booths and for hand-held turbine devices. The hand-held turbine devices are considered to be safe and do not need/require many of the safety precautions that the automated spray booths require.
The study that was used in the report presented by the media was done by the European Commission Scientific Study on Consumer Safety:

Spray tanning technique
The techniques that should be used are designed to minimize dihydroxyacetone (DHA) exposure to the clients. The suggested treatment time consists of less than two minutes of spraying with approximately 50 mL of product. The spray pattern should be designed to push the overspray to the ground, minimizing it and, recommend using an extraction fan if you do not have proper room ventilation.
Products
The report by the European Commission shows that high levels of DHA should not be inhaled by either the technician or the client. Most “rapid-developing” products that are on the market have active ingredient levels of 14-22%, which are considered too high for inhalation.
The U.S. Food & Drug Administration (FDA)
DHA (the same active ingredient in every self-tanner, spray tan or sunless tanning treatment) has been approved for decades by the FDA for cosmetic use. As there have been no studies on inhalation and exposure done directly by the FDA (even though the European Commission has done studies), they advise that the products should not be used in the mucous membranes.(*Source: Skin Inc.

Skin Essentials uses a hand-held turbine device for sunless tanning and we use extraction fans. We also have all suggested safety items available to our clients: nose filters, eye covers, undergarments and lip balm.
